What Is The Role Of Antigens In The Immune System
Complex: Many ways immune system is involved. Prevalent theory that "immune surveillance" is keeping cancers from developing in healthy people. That is one reason why cancers are more prevalent as we age. Also why certain cancers are found in high incidence in people with immune suppression (aids, organ transplant recipients, etc). Newer therapies also use some parts of the immune system to work. ...Read moreSee 1 more doctor answer
Innate and Adaptive: Innate or non-specific immunity involves the skin, lining of the GI tract, respiratory tract, gu tract, etc; and adaptive immunity that involves cells (primarily lymphocytes). Both types of immunity can affect the graft and trigger rejection. In addition, immune responses involve the formation of both cells and antibodies (proteins) that are reactive against the transplanted organ. ...Read moreSee 2 more doctor answers
Type 1 diabetes...: First, not all Insulin dependent diabetics are type 1, typically considered juvenile onset. Type 1 is characterized by the beta cells of the pancreas being destroyed by an autoimmune disease, probably set in motion by a viral infection. No intervention has yet been defined, although studies have shown that the use of certain drugs can delay the onset time! ...Read more
Endocrine: Each hormone is a chemical that control function of many different organs. Brain hormones send orders to organs to work. Brain secretes TSH to order thyroid to work to control whole body. Sexual hormones control brain and whole body, as does Insulin controls use of sugar in whole body (brain included). Then hormones are inter-dependent. Delicate balance! ...Read more

Lymph nodes: They act as a repository for lymphocytes which is one of several defenses we have to fight infection. ...Read more
Keep air sacs open: Surfactants, which are made by the body and are also available as a medication for babies who are deficient in them (usually premie), coat the inside of the tiny air sacs in the lung and keep them open when you exhale. Just like a collapsed balloon is hard to inflate, a collapsed air sac is hard to open. When it doesn't close completely, it's easier to open with the next breath. ...Read more
Why?: The average layperson is woefully clueless about how incredibly complex and finely tuned our immune systems are. Please repost your question with an explanation of why you think the health of your immune system NEEDS improving. Are you HIV-positive or have some inherited form of immune deficiency? If not, you're probably better off finding something else to worry about. ...Read moreSee 1 more doctor answer
Bacteria: We have bacterial and other microorganisms as part of our systems on all integumentary surfaces (skin and mucous membranes). They play differing roles in our body. Some provide for degradation of food substances, some we have not worked out the function for. You need to take a course in microbiology since cannot be all explained here. ...Read more
All organs: The immune system functions to a degree in all the organs of your body. So, an infection anywhere will eventually be noticed and attacked. Certain organs, like the brain, eye, and testes are immune "privileged"--the immune cells will ignore those tissues to minimize the chance of disrupting their function. That is, unless something is seriously wrong (like a major infection). ...Read more
Not really: Lymph nodes are stations connected by chains lymphatics they are the filter for toxins and alert soldiers like tonsils are the first soldiers and try to limit infection there. Immunity is in blood igg and mucous iga. ...Read more
