Immunosuppression is a reduction of the activation or efficacy of the immune system. Some portions of the immune system itself have immunosuppressive effects on other parts of the immune system, and immunosuppression may occur as an adverse reaction to treatment of other conditions. [1] [2]
Immunodeficiency, also known as immunocompromisation, is a state in which the immune system's ability to fight infectious diseases and cancer is compromised or entirely absent. Most cases are acquired ("secondary") due to extrinsic factors that affect the patient's immune system.
The lack of naïve T lymphocytes is the cause of low plasticity of the immune system in the elderly. [11] In aging of the immune system is also a decrease in central tolerance and an increase in the number of autoreactive T cells. [12] B cells also have a decreased repertoire of naïve cells and an increase in memory B cells. [13]

Many species have two major ...
Today, I have lowered heart function, altered capacity in my lungs, and a suppressed immune system. I had a kidney transplant about 14 years ago and have limited mobility from different surgeries.
Immune tolerance is an important means by which growing tumors, which have mutated proteins and altered antigen expression, prevent elimination by the host immune system. It is well recognized that tumors are a complex and dynamic population of cells composed of transformed cells as well as stromal cells , blood vessels, tissue macrophages, and ...
Immune reconstitution inflammatory syndrome (IRIS) is a condition seen in some cases of HIV/AIDS or immunosuppression, in which the immune system begins to recover, but then responds to a previously acquired opportunistic infection with an overwhelming inflammatory response that paradoxically makes the symptoms of infection worse.
