Antibodies serve an important role in the immune system by detecting cells and substances that the rest of the immune system then eliminates. These cells and substances can be foreign (for example, viruses) and also can be produced by the body (for example, cancer cells). Antibodies against the body's own products are called autoantibodies.
Antibodies are produced by B cells in two ways: (i) randomly, and (ii) in response to a foreign protein or substance within the body. Initially, one B cell produces one specific kind of antibody. In either case, the B cell is allowed to proliferate or is killed off through a process called clonal deletion. Normally, the immune system is able to ...
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 ...
Diabetes is very common. The Centers for Disease Control and Prevention (CDC) notes that 38.4 million people in the United States are currently living with diabetes. That’s 11.6 percent of the ...
Autoimmunity means presence of antibodies or T cells that react with self-protein and is present in all individuals, even in normal health state. It causes autoimmune diseases if self-reactivity can lead to tissue damage. [4]
An antibody is made up of two heavy chains and two light chains. The unique variable region allows an antibody to recognize its matching antigen. [73] A B cell identifies pathogens when antibodies on its surface bind to a specific foreign antigen. [74] This antigen/antibody complex is taken up by the B cell and processed by proteolysis into ...
Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.
Diabetes mellitus (DM) is a type of metabolic disease characterized by hyperglycemia. It is caused by either defected insulin secretion or damaged biological function, or both. The high-level blood glucose for a long time will lead to dysfunction of a variety of tissues. [1]
