An immune disorder is a dysfunction of the immune system. [1] These disorders can be characterized in several different ways: By the component(s) of the immune system affected; By whether the immune system is overactive or underactive; By whether the condition is congenital or acquired
The complement system is part of the innate as well as the adaptive immune system; it is a group of circulating proteins that can bind pathogens and form a membrane attack complex. Complement deficiencies are the result of a lack of any of these proteins. They may predispose to infections but also to autoimmune conditions. [7]
Officials of the Marine Hospital Service in New York decided to open a research laboratory to study the link between microscopic organisms and infectious diseases. Joseph J. Kinyoun, a medical officer with the Marine Hospital Service, was selected to create this laboratory, which he called a "laboratory of hygiene." [4]
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 ...
This article provides a list of autoimmune diseases. These conditions, where the body's immune system mistakenly attacks its own cells, affect a range of organs and systems within the body. Each disorder is listed with the primary organ or body part that it affects and the associated autoantibodies that are typically found in people diagnosed ...
Primary immunodeficiencies are disorders in which part of the body's immune system is missing or does not function normally. [1] To be considered a primary immunodeficiency (PID), the immune deficiency must be inborn, not caused by secondary factors such as other disease, drug treatment, or environmental exposure to toxins.
Inflammation is an important and growing area of biomedical research and health care because inflammation mediates and is the primary driver of many medical disorders and autoimmune diseases, including ankylosing spondylitis, psoriasis, psoriatic arthritis, Behçet's disease, rheumatoid arthritis, inflammatory bowel disease (IBD), and allergy ...
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]
