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 ...
Similarly, there is a research project called the Immunological Genome Project whose stated goal is to generate "a complete microarray dissection of gene expression and its regulation in the immune system of the mouse". In other words, the project is trying to define and characterize the immunome of the mouse.
Immunology is a branch of biology and medicine [1] that covers the study of immune systems [2] in all organisms.. Immunology charts, measures, and contextualizes the physiological functioning of the immune system in states of both health and diseases; malfunctions of the immune system in immunological disorders (such as autoimmune diseases, hypersensitivities, [3] immune deficiency, [4] and ...
A representation of the cholera epidemic of the 19th century. For thousands of years mankind has been intrigued with the causes of disease and the concept of immunity. The prehistoric view was that disease was caused by supernatural forces, and that illness was a form of theurgic punishment for "bad deeds" or "evil thoughts" visited upon the soul by the gods or by one's enemies.

Numerous new immunosuppressive drugs are being actively tested for SLE. Rather than broadly suppressing the immune system, as corticosteroids do, they target the responses of specific types of immune cells. Some of these drugs are already FDA-approved for treatment of rheumatoid arthritis, however due to high-toxicity, their use remains limited.
An immune response is a physiological reaction which occurs within an organism in the context of inflammation for the purpose of defending against exogenous factors. These include a wide variety of different toxins, viruses, intra- and extracellular bacteria, protozoa, helminths, and fungi which could cause serious problems to the health of the host organism if not cleared from the body.
Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
The immune system is often involved with inflammatory disorders, as demonstrated in both allergic reactions and some myopathies, with many immune system disorders resulting in abnormal inflammation. Non-immune diseases with causal origins in inflammatory processes include cancer, atherosclerosis , and ischemic heart disease .
