Immunoglobulin class switching, also known as isotype switching, isotypic commutation or class-switch recombination ( CSR ), is a biological mechanism that changes a B cell 's production of immunoglobulin from one type to another, such as from the isotype IgM to the isotype IgG. [ 1] During this process, the constant-region portion of the ...
Interleukin 10 (IL-10) is a protein that inhibits the synthesis of a number of cytokines, including IFN-gamma, IL-2, IL-3, TNF, and GM-CSF produced by activated macrophages and by helper T cells. In structure, IL-10 is a protein of about 160 amino acids that contains four conserved cysteines involved in disulphide bonds. [33]

State switching (a.k.a. phenotypic switching) is a fundamental physiological process in which a cell/organism undergoes spontaneous, and potentially reversible, transitions between different phenotypes. Thus, the ability to switch states/phenotypes ( phenotypic plasticity) is a key feature of development and normal function of cells within most ...
Interleukin-2 ( IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15.5–16 kDa protein [5] that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 is part of the body's natural response to microbial infection, and in discriminating ...
Supervision (telephony) In telecommunication, supervision is the monitoring of a telecommunication circuit for telephony to convey to an operator, user, or a switching system, information about the operational state of the circuit. The typical operational states of trunks and lines are the idle and busy states, seizure, and disconnect. [1]
