Disorders of the Immune System
Disorders of the immune system can be broken down into four main categories:
- immunodeficiency disorders (primary or acquired)
- autoimmune disorders (in which the body's own immune system attacks its own tissue as foreign matter)
- allergic disorders (in which the immune system overreacts in response to an antigen)
- cancers of the immune system
Immunodeficiencies occur when a part of the immune system is not present or is not working properly. Sometimes a person is born with an immunodeficiency --- these are called primary immunodeficiencies. (Although primary immunodeficiencies are conditions that a person is born with, symptoms of the disorder sometimes may not show up until later in life.) Immunodeficiencies can also be acquired through infection or produced by drugs. These are sometimes called secondary immunodeficiencies. Immunodeficiencies can affect B lymphocytes, T lymphocytes, or phagocytes. Some examples of primary immunodeficiencies that can affect kids and teens are:
- IgA deficiency is the most common immunodeficiency disorder. IgA is an immunoglobulin that is found primarily in the saliva and other body fluids that help guard the entrances to the body. IgA deficiency is a disorder in which the body doesn't produce enough of the antibody IgA. People with IgA deficiency tend to have allergies or get more colds and other respiratory infections, but the condition is usually not severe.
- Severe combined immunodeficiency (SCID) is also known as the "bubble boy disease" after a Texas boy with SCID who lived in a germ-free plastic bubble. SCID is a serious immune system disorder that occurs because of a lack of both B and T lymphocytes, which makes it almost impossible to fight infections.
- DiGeorge syndrome (thymic dysplasia), a birth defect in which children are born without a thymus gland, is an example of a primary T-lymphocyte disease. The thymus gland is where T lymphocytes normally mature.
- Chediak-Higashi syndrome and chronic granulomatous disease both involve the inability of the neutrophils to function normally as phagocytes.
- Acquired immunodeficiencies usually develop after a person has a disease, although they can also be the result of malnutrition, burns, or other medical problems. Certain medicines also can cause problems with the functioning of the immune system.
- Secondary immunodeficiencies include:
- HIV (human immunodeficiency virus) infection/AIDS (acquired immunodeficiency syndrome) is a disease that slowly and steadily destroys the immune system. It is caused by HIV, a virus which wipes out certain types of lymphocytes called T-helper cells. Without T-helper cells, the immune system is unable to defend the body against normally harmless organisms, which can cause life-threatening infections in people who have AIDS. Newborns can get HIV infection from their mothers while in the uterus, during the birth process, or during breastfeeding. People can get HIV infection by having unprotected sexual intercourse with an infected person or from sharing contaminated needles for drugs, steroids, or tattoos.
- Immunodeficiencies caused by medications. Some medicines suppress the immune system. One of the drawbacks of chemotherapy treatment for cancer, for example, is that it not only attacks cancer cells, but other fast-growing, healthy cells, including those found in the bone marrow and other parts of the immune system. In addition, people with autoimmune disorders or who have had organ transplants may need to take immunosuppressant medications. These medicines can also reduce the immune system's ability to fight infections and can cause secondary immunodeficiency.
In autoimmune disorders, the immune system mistakenly attacks the body's healthy organs and tissues as though they were foreign invaders.
Autoimmune diseases include:
- Lupus is a chronic disease marked by muscle and joint pain and inflammation. The abnormal immune response may also involve attacks on the kidneys and other organs.
- Juvenile rheumatoid arthritis is a disease in which the body's immune system acts as though certain body parts such as the joints of the knee, hand, and foot are foreign tissue and attacks them.
- Scleroderma is a chronic autoimmune disease that can lead to inflammation and damage of the skin, joints, and internal organs.
- Ankylosing spondylitis is a disease that involves inflammation of the spine and joints, causing stiffness and pain.
- Juvenile dermatomyositis is a disorder marked by inflammation and damage of the skin and muscles.
Allergic disorders occur when the immune system overreacts to exposure to antigens in the environment. The substances that provoke such attacks are called allergens. The immune response can cause symptoms such as swelling, watery eyes, and sneezing, and even a life-threatening reaction called anaphylaxis. Taking medications called antihistamines can relieve most symptoms.
Allergic disorders include:
- Asthma, a respiratory disorder that can cause breathing problems, frequently involves an allergic response by the lungs. If the lungs are oversensitive to certain allergens (like pollen, molds, animal dander, or dust mites), it can trigger breathing tubes in the lungs to become narrowed, leading to reduced airflow and making it hard for a person to breathe.
- Eczema is an itchy rash also known as atopic dermatitis. Although atopic dermatitis is not necessarily caused by an allergic reaction, it more often occurs in kids and teens who have allergies, hay fever, or asthma or who have a family history of these conditions.
- Allergies of several types can occur in kids and teens. Environmental allergies (to dust mites, for example), seasonal allergies (such as hay fever), drug allergies (reactions to specific medications or drugs), food allergies (such as to nuts), and allergies to toxins (bee stings, for example) are the common conditions people usually refer to as allergies.
- Anaphylactic shock - Anaphylaxis is a severe allergic reaction that occurs rapidly and causes a life-threatening response involving the whole body. This reaction can lead to difficulty breathing and shock ultimately leading to death. For an anaphylactic reaction to occur, you must have been exposed in the past to the substance that causes the reaction, called the antigen. This is called "sensitization."
- A bee sting, for example, may not cause an allergic reaction the first time.
- Another bee sting may produce a sudden, severe allergic reaction known as anaphylaxis or anaphylactic shock.
- These reactions usually occur within seconds to minutes of exposure. Occasionally, they are delayed. You may develop sensitivity and anaphylaxis to a substance that you have been exposed to many times in the past without a reaction, and often people don't recall the previous exposure.
Cancers of the Immune System
Cancer occurs when cells grow out of control. This can also happen with the cells of the immune system. Lymphoma involves the lymphoid tissues and is one of the more common childhood cancers. Leukemia, which involves abnormal overgrowth of leukocytes, is the most common childhood cancer. With current medications most cases of both types of cancer in kids and teens are curable.
Although immune system disorders usually can't be prevented, you can help your child's immune system stay stronger by staying informed about your child's condition and working closely with your doctor.Read Less

Beta Glucan is a natural substance found in such foods as oats, barley, mushrooms and yeasts. Structually, Beta Glucan (Beta 1,3/1,6 Glucan) is classified as a highly refined carbohydrate, made up of a string of glucose molecules, with the fats, proteins and other polysaccharides removed. Beta Glucan used to be very expensive to extract and purify, but recent technological break throughs have resulted in much more cost effective methods, so that now it has become available much cheaper than ever before. Beta Glucan is recognized by the FDA and is given a GRAS (Generally Recognized As Safe) rating.
Beta glucan contributes potent, diverse and overall systemic support to the immune system. The systemic effect on the immune system, can best be described as non-specific immune stimulation combined with free-radical scavenging activity. Considered a biological response modifier of the immune system, beta glucan has been shown to stimulate both humeral and cell-mediated immunity as well as to activate macrophages more effectively than any other agent known. Activating macrophages strengthens the immune system signifiantly and supports the immmume system in numerous ways.
One example of the result of macrophage activation is the appearance of gamma interferon which increases the production of nitric oxide and superoxide, directly leading to an immunological war on microorganisms.
Nothing rivals beta glucan for immune enhancement. There is no other substance man-made or natural that has the published studies, as does beta glucan, to back up it's immune system supporting ability.
And, unlike many other immune support supplements, research suggests that beta glucan does not over stimulate your immune system.
Scientific studies on animals and humans, originating from such prestigious institutions as the University of Saskatchewan in Canada, Baylor College of Medicine, Brown Medical School, Tulane University and Harvard Medical School have demonstrated the great value beta glucan has to support our immune systems
In four different published studies, performed at the University of Saskatchewan (Microbiol. Immun. 41, 1997), (Microbiological Immunity v. 42, 1997), (International Journal of Parasitology v. 27, 1999) and (FEMS Immmunology v. 35, 2003) researchers repeatedly demonstrated the amazing power beta glucan has to stimulate the immune system. Dr. Joyce Czop, at Harvard University, described the mode of action of beta glucan in stimulating the immune system: "there is a specific receptor for beta-1-3-glucan on the surface of certain cells, called macrophages that when activated, stimulate a cascade of events turning the body into "an arsenal of defense".
Recent independent experiments completed at Baylor College of Medicine in the laboratory of Professor Phil Wyde, Ph.D., also indicate the oral effectiveness of Beta-1,3-glucan in stimulating non-specific immunity. Peritoneal macrophages doubled their phagocyte activity in mice fed with Beta-1,3-glucan. This systemic effect of oral application is comparable to that achieved by injection, which makes this material a unique and very valuable oral immunostimulant.
Medical Doctors and researchers at Brown Medical School and Rhode Island hospital have discovered that beta 1,3-D glucan, binds to receptors on neutrophils, the most abundant type of immune cell in the body. The beta glucan caused the neutrophils to take a more direct path to the site of infection rather than the indirect route normally taken.
Neutrophils are attracted to the site of an infection by blood proteins called chemoattractants and are among the first cells of the body to respond to a challenge due to infection or injury. Normally, neutrophils use such chemoattractants as interleukin-8 to travel to the site of infection. However, when neutrophils were treated with beta 1,3-D glucan, the neutrophils bypassed the IL-8 and went directly to the source of infection. Beta 1,3-D appeared to accomplish this by increasing the neutrophils ability to sense complement fragments emanating from the site of an infection. As a result, beta glucan helps neutrophils locate the epicenter of the bacterial infection within tissue.
This ability to make neutrophils bypass IL-8 and go directly to the site of infection can result in a more rapid immune response.
Beta glucan is recommended before and after cancer surgery to support healing.
In general, beta glucan stimulates macrophages and improves all immune functions, including phagocytosis (ability to engulf foreign cells and particles) release of certain cytokines (intercellular hormones) IL-1, IL-6, GM-CSF, interferons, and the processing of antigens.
The macrophage stays in an alert or ready mode until the presence of "non-self" invaders are detected, at which time the macrophage is activated and becomes the first line of defense against these invaders.
Unlike many other immune support supplements, research suggests that beta glucan does not over stimulate your immune system.Read Less
Alpha Lipoic Acid
Alpha Lipoic Acid (also known as thioctic acid or lipoic acid) is a very powerful, natural antioxidant, and is thought to be important for helping support the immune system. Alpha Lipoic Acid is found in potatoes, broccoli, and liver and also occurs naturally in our bodies, but not in the free form. The body actually converts Alpha Lipoic Acid (ALA) to DiHydro Lipoc Acid (DHLA).
ALA and its cousin DHLA are often referred to as the "ultimate universal antioxidants". They (referred to collectively as LA) are the only antioxidants that are both fat and water soluble. Both can actually cross the blood/brain barrier to enter the brain. These unique qualities are important, because it means that LA can access all parts of all cells, giving it tremendous ability to scavenge free radicals wherever they may be. Additionally, LA can also recharge other antioxidants that have been used up. In the body, LA helps regenerate other antioxidants such as vitamin C, vitamin E and glutathione.
In addition to serving as the hub of the body's antioxidant network, lipoic acid is the only antioxidant that can boost the level of intracellular glutathione, a cellular antioxidant of tremendous importance.
Besides being the body's primary water-soluble antioxidant and a major detoxification agent, glutathione is absolutely essential for the functioning of the immune system. Scientists have known for over two decades that maintaining a high cellular level of glutathione is critical for life and crucial for health.
Raising glutathione levels has been shown to alter the cytokine balance in favor of a Th1 immune response mode (the anti-cancer and anti-viral mode of the immune defense) (Peterson JD et al., 1998). Agents that deplete glutathione, such as ethanol, have been shown to impair the body's immune defense. TNF-a (tumor necrosis factor alpha), which increases in many diseases of aging, has been shown to be involved in depletion of cellular glutathione. and is thought to be a major factor in the immune decline associated with aging (Phelps DT et al., 1995).
People with chronic illnesses such as AIDS, cancer and autoimmune diseases generally have very low levels of glutathione. White blood cells are particularly sensitive to changes in glutathione levels, and even subtle changes may have profound effects on the immune response. It was shown that glutathione deficiency in HIV-infected individuals correlates with decreased survival (Herzenberg LA et al., 1997).
Dr. Packer and Chandan K. Sen, researchers from Finland, have described how alpha-lipoic acid regulates aspects of the immune system, and in particular, T-lymphocytes. They have discovered that ALA boosts glutathione levels in T cells, These two researchers, along with other scientists, have reported how alpha-lipoic acid may help people with HIV or other immune suppressed conditions.
In a pilot study, supplementation with 150 mg of ALA 3 times per day was shown to increase plasma ascorbate, glutathione and T-helper cells and to optimize the ratio of T-helper cells to T-suppressor cells. Other studies have demonstrated the ALA helps to inhibit HIV replication by decreasing the activity of reverse transcriptase and to delay apoptosis (programmed cell death) of Thymus cells - the immune system's number one line of defense.
The practical problem for those who wish to maintain healthful glutathione levels is that taking glutathione itself as a supplement does not boost cellular glutathione levels, since glutathione breaks down in the digestive tract before it reaches the cells. Therefore, the discovery that lipoic acid can effectively boost glutathione levels has very important implications We actually get very little Lipoic acid in our food, Broccoli (one of the best food sources) for example, contains a mere 100 micrograms per 100 gram serving. This means you would have to eat over two pounds of broccoli to get one single milligram.
ALA supplementation is the only way to get the benefits of this powerful universal antioxidant and to enjoy the resulting increase in intracellular glutathione, which may help support a healthy immune system.Read Less
Tri Methyl Glycine
Trimethylglycine (TMG) also known as anhydrous betaine, is a naturally occurring phyto-nutrient found in a variety of plants and animals, with its highest concentrations found in beets, leafy green vegetables, and legumes. Since it can be difficult to eat enough of these foods to provide the body with sufficient methyl groups, supplementation is necessary.
Chemically, TMG functions as a Methyl Donor, which is why it has a great ability to reduce elevated levels of homocysteine to normal. In fact TMG is such a good methyl doner that in addition to effectively lowering the levels of HOMOCYSTEINE, it also increases the beneficial S-adenosyl-methionine (SAM) levels. Furthermore, after losing its methyl group, TMG becomes DMG (dimethylglycine), a well recognized energy-boosting nutrient.
TMG has got all the properties of DMG but because it has one extra methyl group, it is known to be a more efficient methyl donor than DMG. After methyl donation, it stays useful in the metabolism as DMG thus having a double benefit. This is also known as BETAINE.
DMG is an amino acid that is predominantly found in grains. It is a member of the family of nutrients that include choline, betaine (trimethyl-glycine), sarcosine (methylglycine) and glycine. This family of compounds supplies the body with an essential biochemical group (a methyl group) that allows conversions of substances in the bodies intricate biochemical pathways.
In two independent studies, researchers at the Medical University of South Carolina and at Clemson University, have both suggested that TMG supports a healthy immune system.
- The first research project, done at the Medical University of South Carolina yielded the following results. Using 120 mg. DMG for eight weeks resulted in an average of a four-fold increase in antibody production in-vivo (in the body, not a test tube) when exposed to pneumovax-SSS and a "significant" increase when exposed to streptokinase -streptodornase antigen. A third antigen, concanavalin A showed little difference in the control and DMG treated groups response. This antibody response, or humoral response, is accomplished by the B-lymphocytes. A second part of this project demonstrated the T-lymphocyte response. In normal subjects the T cell activity was increased by more than 50%. Even more important was the fact that subjects with a less than normal lymphocyte activity, in this case due to sickle cell anemia or diabetes, there was a two- to three-fold increase in lymphocyte response. As these patients are more susceptible to infections, DMG may be an especially important nutrient.
- A second study at Clemson University showed similar results. The anti-body production to typhoid and influenza antigen in rabbits increased three- to five-fold. T cell populations were also increased. Further, the study demonstrated a doubling of the interferon production of T cells.
- Other effects of DMG have been studied for over fifty years. The earliest interest in this nutrient stems from it's effect on athletes. In 1965 it was established that DMG increases the oxygen utilization within the cell. This alone will increase the amount of exercise one can perform. It also is useful for people travelling to higher elevations. Research at USC School of Medicine in 1979 showed that the amount of lactic acid buildup in muscles after exercise is decreased with the use of DMG. Lactic acid is thought to be one of the factors in muscular soreness after exercise.
- DMG causes the adrenal glands to secrete more corticosteroids, which can effect blood sugar levels, as well as the metabolism of protein and fat. It has been found to enhance liver function and to support healthy cholesterol levels by increasing synthesis and secretion of bile. The supportive effect of DMG supplementation on skin conditions, such as psoriasis and eczema is a hot research topic. DMG also acts as an antioxidant preventing the actions of free radicals which may damage the cells of the immune system.
Colostrum is the pre-milk fluid produced from the mother's mammary glands during the first 72 hours after birth. Colostrum provides life-supporting immune and growth factors that insure the health and vitality of the newborn.
Colostrum is the first food of life! Immune and growth factors in colostrum provide the newborn with the essential nutrients needed to begin a healthy life. It is gernally regarded as safe for all ages.
While it's relatively new on the market, colostrum has been used for thousands of years to help maintain the health of people worldwide.
We know that cow's milk provides our bodies with vitamin D and calcium, but our four-legged friends provide an even more powerful substance for our health, -- bovine colostrum. Colostrum is the nutrient-rich, pre-milk fluid that is secreted by the mammary glands of female mammals to nourish their young.
Bovine (cow) colostrum is nearly identical to human colostrum but research suggests it is four times richer in immune factors than human colostrum. Best of all, bovine colostrum may help support a healthy immune system to all mammals -- humans -- and pets as well!
Immune factors in colostrum can help balance and support a healthy immune system; which is the key to good health.
Growth factors supply the necessary building blocks for the newborn, enhancing the growth of cells, muscles, tissue, bone and cartilage. As we age, our bodies produce less and less of these vital factors, increasing signs of aging, and making it more difficult for us to fight disease.
Pollution, toxins, carcinogens, smoking, alcohol and overuse of antibiotics can lead to a decrease in our immune response, resulting in disease. Colostrum supports the body's ability to function properly in both newborns and adults, even for our pets!
Most experts agree that the majority of disease and illness begins in the gastrointestinal tract. Pathogens (viruses, bacteria, yeast, and fungus) enter the body through our nose, ears, and mouth and can attach themselves to the lining of the bowel, where they grow and multiply, causing a huge variety of diseases. Colostrum helps inhibit the binding of pathogens to the bowel lining, so they are unable to proliferate.
All humans are exposed to these deadly invaders throughout their lives. Unfortunately, these days, they are in the air we breathe and the food we eat. When our bodies are healthy, our immune system fights off these pathogens without needing any help. However, if our immune system is compromised in any way (which is unfortunately true for most of us), colostrum can help our bodies support proper immune function.Read Less
Elderberry Extract is derived from the berries of the fragrant, flowering Elder tree. The Elder tree berry has also been used for hundreds of years as a natural intestinal cleanser and an eye wash. Today, Both the flower and the berry are revered for their powerful antioxidant properties that support good health by attacking harmful free radicals that damage cells. Elderberries also nourish the circulatory system.
There are several active ingredients in Elderberries. Analytical research conducted in Europe shows that elderberries are concentrated sources of anthocyanins (potent purple pigments known as flavonoids) that have great health benefits. Elderberries are also rich in tannins and vitiamin C. Ongoing research in Europe is focusing on the anthocyanins found in elderberries. According to this research, these anthocyanins possess noticably more antioxidant capacity than either vitamin E or vitamin C. The research also suggest that elderberry anthocyanins support the immune system by boosting the production of cytokines.
These unique proteins act as messengers in the immune system to help regulate immune response.
Virologist Madeline Mumcuoglu, Ph.D., has done extensive research on how elderberry supports immune health. She found that the action of elderberry extract effects viral hemagglutinin, or the process by which the invading cells use their spike-like projections to introduce their enzyme into healthy cell membranes. She also noticed that the viral enzyme is neutralized in the presence of elderberry extract.
Andrographis paniculata is a shrub found throughout China, India and other countries in subtropical and Southeast Asia. Both the fresh and dried leaves, as well as the fresh juice of the whole plant, have been used as a popular herb in Chiinese medicine. Modern science has finally taken note, and now researchers have isolated a number of the herb's active ingredients. Chief among these phytochemicals are diterpene lactones known as andrographolides, which exert their effects, on tissues of the blood cell-producing bone marrow and/or spleen.
Chinese researchers have discovered that one such compound, andrographanin, enhances the ability of certain white blood cells to recognize and neutralize foreign cells. It is important to note that purified, concentrated bioactive andrographolides extracted from andrographis are far more potent, at considerably lower doses, than the crude herb alone.
In animal and human clinical trials, Armenian scientists have demonstrated that andrographolides are readily absorbed into the bloodstream following the oral ingestion of andrographis herb extract.
In Sweden, scientists conducted a randomized, double-blind, placebo-controlled study of standardized andrographis extract in the treatment of upper-respiratory tract infections (the common cold). More than 200 patients participated in the clinical trial.
Russian researchers conducted a similar randomized trial of an andrographis extract preparation for the treatment of acute upper-respiratory viral infection.
Scientists in Thailand conducted a systematic review of the published literature and a meta-analysis of all randomized, controlled trials of andrographis for the symptomatic treatment of upper-respiratory tract infections. By pooling results from a number of disparate trials, they were able to arrive at an "overall estimate of effect." The studies included in their statistical analysis featured results from 433 patients.
Researchers in all of these studies have concluded that andrographis support a healthy immune system.Read Less
Selenium is a significant cellular antioxidant and is thought to help support a healthy immune system. Some researcher believe that certain viruses become stronger and hardier in selenium-deficient people. Similarly, selenium-deficient animals are thought to be more susceptible to cardiac damage from viruses. Animals with selenium deficiency are thought to have lesss effective neutrophils.
More than any other micronutrient deficiency, selenium deficiency is highly correlated to viral progression and death in HIV infection. Supplementation with selenium in deficient HIV-positive people has been shown to improve selenium status. Although selenium supplementation doesn't always result in improvement in T-cell counts, in a few studies, blood selenium correlated with CD4+ counts. Researchers are investigating this correlation further to see what role it may play in supporting the immune system in those with HIV.
In the 80 years since its discovery (by Albert Szent-Gyorgyi), vitamin C has come to be known as a "wonder worker." It's easy to see why: In addition to its role in collagen formation and other life-sustaining functions, vitamin C serves as a key immune system nutrient and a potent free-radical fighter. This double-duty nutrient is key to its support of a healthy immune system.
Vitamin C is a water-soluble vitamin and is known as ascorbic acid . . . meaning "without scurvy" (the disease caused by a vitamin C deficiency). Most species of animals have the ability to synthesize Vitamin C in their liver from glucose. Human beings however, are among only a handful of animals, including primates and guinea pigs, who cannot produce their own supply of vitamin C. We depend on ascorbic acid for many aspects of our biochemical functioning, and so we have no choice but to obtain this nutrient in our diet or through supplementation.
Vitamin C can be found in fruits such as oranges, grapefruits, tangerines, lemons, limes, papaya, strawberries and cantaloupe. Vitamin C and bioflavonoids - the watersoluble substances that help to protect your capillaries - are found in the white linings of these and other plants. Many vegetables also pack in vitamin C including tomatoes, broccoli, green and red bell peppers, raw lettuce and other leafy greens.
Vitamin C is absorbed by an active transport system located in the gut and then reabsorbed through the kidneys. Since the absorption mechanisms in the gut and kidneys can reach a saturation point, it is better to take multiple doses of vitamin C throughout the day than one large dose.
Vitamin C supports the immune system by stimulating the activity of antibodies and immune system cells such as phagocytes and neutrophils. As a constituent of collagen, vitamin C may contribute to our immune defenses in an even more fundamental way: our skin and the epithelial lining of the body's orifices, both of which contain collagen, serve as our first line of defense against foreign invaders. They prevent these invaders from entering the body in the first place, where the immune system would have to go to war against them.
Beyond that, vitamin C supports the body's fight against the toxic effects of environmental pollutants by stimulating liver detoxifying enzymes. It also stimulates the production of PGE1, a prostaglandin which assists lymphocytes, the defender cells in our immune system.
The immune system process called phagocytosis, in which certain cells "eat" invading bacteria, is stimulated by vitamin C. In addition, the nutrient may reduce the suppressor activity of the mononuclear leukocytes, which weakens the overall effectiveness of the immune system.
As an antioxidant, vitamin C's primary role is to neutralize free radicals. Since ascorbic acid is water soluble, it can work both inside and outside the cells to combat free radical damage. Free radicals will seek out an electron to regain their stability and Vitamin C is an excellent source of electrons; therefore, it "can donate electrons to free radicals such as hydroxyl and superoxide radicals and quench their reactivity," states Adrianne Bendich in "Antioxidant Micronutrients and Immune Responses".
Much like the immune system itself, which operates at a cellular level, the hardworking vitamin C reaches every cell of the body. The concentration of vitamin C in both blood serum and tissues is quite high.Read Less
Vitamin B12 (Cobolamine)
Vitamin B12 is an essential cofactor for immune system function. Vitamin B12 deficiency has been shown to depress both cell-mediated and humoral immune responses. Research suggests that even people with only marginally low levels of B-vitamins show signs of weakened immune systems and that the B Vitamins may help support B-cell and T-cell function.
Folate (Vitamin B9) (aka Pteroylglutamic acid)
Folic acid plays a crucial role in DNA and protein synthesis and is required for the normal cycle of cell division and prliferation, therefore, effecting the proliferative response of immune cells. Animal and human studies in folate deficient subjets have demonstrated reduced lymphocyte DTH response and natural killer cell activity. Cell-mediated immunity is especially effected by folate deficiency: the blastogenic response of T lymphocytes to certain mitogens is decreased in folate-deficient humans and animals, and the thymus is preferentially altered. The effects of folic acid deficiency upon humoral immunity have been more thoroughly investigated in animals than in humans, and the antibody responses to several antigens have been shown to decrease. Conversely, the phagocytic and bactericidal capacities of polymorphonuclear cells have been studied mainly in folate-deficient humans.
