Immunotoxicology (sometimes abbreviated as ITOX) is the study of the toxicity of foreign substances called xenobiotics and their effects on the immune system. [1] Some toxic agents that are known to alter the immune system include: industrial chemicals, heavy metals, agrochemicals, pharmaceuticals, drugs, ultraviolet radiation, air pollutants and some biological materials.
Interleukin-2 is an important immune system regulator necessary for the clone expansion and survival of activated lymphocytes T. Its effects are mediated by the trimer cell surface receptor IL-2a, consisting of the α, β, and γ chains. The IL-2a (CD25, T-cell activation antigen, TAC) is expressed only by the already-activated T lymphocytes.
Azathioprine White blood cells (and red blood cells). Administration of immunosuppressive medications or immunosuppressants is the main method for deliberately inducing immunosuppression; in optimal circumstances, immunosuppressive drugs primarily target hyperactive components of the immune system.

The ability of the immune system to respond to pathogens is diminished in both the young and the elderly, with immune responses beginning to decline at around 50 years of age due to immunosenescence. [ 112 ] [ 113 ] In developed countries , obesity , alcoholism , and drug use are common causes of poor immune function, while malnutrition is the ...
For moderate to severe CRS, the use of immunosuppressive agents like corticosteroids may be necessary, but judgment must be used to avoid negating the effect of drugs intended to activate the immune system. [5] Tocilizumab, an anti-IL-6 monoclonal antibody, was FDA approved for steroid-refractory CRS based on retrospective case study data. [5] [6]
Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine. [2] The risk is especially high in cytotoxic chemotherapy for leukemia. In the case of non-small-cell lung cancer, myelosuppression predisposition was shown to be modulated by enhancer mutations. [3]
The long-term effects of increased temperatures on the immune system are unknown; find out more about the study here. The post New Study Reveals Climate Change May Affect Immune Performance ...
Antimicrobial peptides (AMPs), also called host defence peptides (HDPs) are part of the innate immune response found among all classes of life. Fundamental differences exist between prokaryotic and eukaryotic cells that may represent targets for antimicrobial peptides .
