  Immune system - Wikipedia, the free encyclopedia
The adaptive immune system, also called the "acquired immune system", ensures that most mammals that survive an initial infection by a pathogen are generally immune to further illness, caused by that same pathogen.
The adaptive immune system is based on dedicated immune cells termed leukocytes (white blood cells) that are produced by stem cells in the bone marrow, and mature in the thymus and/or lymph nodes.
Suppression of the immune system is often used to control autoimmune disorders or inflammation when this causes excessive tissue damage, and to prevent transplant rejection after an organ transplant.

 MedlinePlus Medical Encyclopedia: Immune response
The immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful to the body.
Immune system disorders occur when the immune response is inappropriate, excessive, or lacking.
Transplant rejection involves the destruction of transplanted tissues or organs and is a major complication of organ transplantation.

 Aging and the Immune System
The immune system, which is responsible for fighting infection, simply does not function as efficiently in older adults as in younger people.
The body at this age probably still has the ability to generate fevers and other immunity weapons, but the central nervous system is simply less sensitive to immune signals and doesn't react as quickly or efficiently to infection.
While vaccines do not work as well in the immune system of older adults, vaccinations for diseases such as influenza, pneumonia, hepatitis B, tuberculosis, diphtheria and tetanus have been found to reduce mortality in the elderly and are still worthwhile.

 Immune system - Encyclopedia.WorldSearch   (Site not responding. Last check: 2007-11-07)
The immune system is the collection of organs and tissues involved in the adaptive defense of a body against foreign biological material.
It may be broken down into the adaptive immune system, composed of four lymphoid organs (thymus, lymph nodes, spleen and submucosal lymphoid nodules) and the group motile cells that are involved in the body's defense against foreign bodies.
Adjuvants, or chemicals that stimulate an immune response, provide this "second signal" in procedures when an antigen that would not normally raise an immune response is artificially introduced into a host.

Macrophages are the immune cells that filter lymph, consuming bacteria and cellular debris while protecting the lymph system from invasion and damage.
This immune response is tailored to specific antigens and is vital to resisting infection from mold-like bacteria including yeast, fungi, parasites and such viruses as Epstein-Barr, herpes simplex and hepatitis.
However, there are numerous natural remedies that are capable of stimulating a sluggish immune system-empowering it to respond to a number of assaults by viruses and bacteria.

 The Body: The Immune System -- An Overview
The immune system is composed of many interdependent cell types that collectively protect the body from bacterial, parasitic, fungal, viral infections and from the growth of tumor cells.
An immune response is initiated when the macrophage or dendritic cells present the antigen to the appropriate B or T cells.
An immune response to foreign antigen requires the presence of an antigen-presenting cell (APC), (usually either a macrophage or dendritic cell) in combination with a B cell or T cell.

 Immune response
The immune response is the way the body recognizes and defends itself against microorganisms, viruses, and substances recognized as foreign and potentially harmful to the body.
Some of these barriers are: the skin, stomach acid, mucous (traps microorganisms and small particles), the cough reflex, and enzymes in tears and skin oils.
In some cases, suppression of the immune system is necessary (for example, in the treatment of autoimmune disorders or allergies).

The immune system protects us from invaders in the form of bacteria, viruses and so on, if we supply it with the proper materials.

 Immune System
The immune system has a series of dual natures, the most important of which is self/non-self recognition.
Parts of the immune system are antigen-specific (they recognize and act against particular antigens), systemic (not confined to the initial infection site, but work throughout the body), and have memory (recognize and mount an even stronger attack to the same antigen the next time).
The goal of all vaccines is promote a primary immune reaction so that when the organism is again exposed to the antigen, a much stronger secondary immune response will be elicited.

 Immune System Health
The immune system is a complex network of specialized cells and organs that has evolved to defend the body against attacks by "foreign" invaders.
The human body provides an ideal habitat for many of them and they try to break in; because the presence of these organisms is often harmful, the body's immune system will attempt to bar their entry or, failing that, to seek out and destroy them.
The immune system displays both enormous diversity and extraordinary specificity; not only is it able to recognize many millions of distinctive nonself molecules, it can produce molecules and cells to match up with and counteract each one of them.
