one of a group of proteins released by cells of the immune system that carry signals to neighboring cells to regulate and/or promote an immune response

A small protein released by cells that has a specific effect on the interactions between cells, on communications between cells or on the behavior of cells. The cytokines includes the interleukins, lymphokines and cell signal molecules, such as tumor necrosis factor and the interferons, which trigger inflammation and respond to infections.

A type of protein that is made by certain immune and non-immune cells and has an effect on the immune system. Some cytokines stimulate the immune system and others slow it down. They can also be made [..]

Any of a group of soluble proteins that are released by a cell causing a change in function or development of the same cell (autocrine), an adjacent cell (paracrine), or a distant cell (endocrine); cy [..]

A potent immunomodulator that is secreted by an immune cell and affects host response to infection or tissue trauma; can be a protein or glyocoprotein; examples are interleukins or interferons. [..]

A molecule secreted by an activated or stimulated cell, for example, macrophages, that causes physiological changes in certain other cells. cytokinesis

any of various minute peptides or proteins which are dispersed by cells as alerts to those or other cells. Each kind arouses an objective cell which has a certain receptor for that cytokine.

A protein that induces the proliferation of other cells, as in the immune system. Examples include interleukins and interferons.

Any of various regulatory proteins, such as the interleukins

A chemical messenger secreted by immune cells to regulate immune activity.

Definition: (SY-toe-kyn) A class of substances that are produced by cells of the immune system and can affect the immune response. Not very different from hormones.

Any of numerous secreted, small proteins (e.g., interferons, interleukins) that bind to cell-surface receptors on certain cells to trigger their differentiation or proliferation.

Cytokines are small molecules that are released by cells to modify the behaviour of the surrounding cells. Cytokines play a major role in modulating the immune system. Among the large number of cytoki [..]

a protein made by cells that affects the behavior of other cells. Cytokines act on specific cytokine receptors in the cells they affect.

A family of proteins produced by cells, especially by immune cells. Cytokines act as chemical messengers between cells to regulate immune responses. See Related Term(s): Interferon, Interleukin-2, Interleukin-7

A protein secreted by cells of the immune system that helps regulate inflammatory responses.

A substance that is made by cells of the immune system. Some cytokines can boost the immune response and others can suppress it. Cytokines can also be made in the laboratory by recombinant DNA technology and used in the treatment of various diseases, including cancer.

a soluble, hormone-like protein produced by white blood cells that acts as a messenger between cells. Cytokines can stimulate or inhibit the growth and activity of various immune cells. Cytokines are [..]

a class of substance secreted by cells of the immune system to regulate immune cells.

Proteins manufactured by cells of various lineages that, when secreted, drive specific responses (e.g., proliferation, growth, or maturation) in other susceptible cells.

Cytokines are cell signalling molecules that modulate the immune system response. Cytokines can either be peptides, proteins or glycoproteins, and they include the sub-groups: interleukins, interferon and growth factors. Their main purpose is to initiate the movement of cells towards sites of either trauma, infection or inflammation. 

Cytokines are cell signalling molecules that modulate the immune system response. Cytokines can either be peptides, proteins or glycoproteins, and they include the sub-groups: interleukins, interferon [..]

A type of protein that has an effect on the immune system. Some cytokines stimulate the immune system and others slow it down. Cytokines are often produced by immune cells but can also be produced by [..]

A soluble protein mediating signals between different or the same cell population (e.g., interleukin-1, interleukin-2).

These are hormones produced by white blood cells (lymphocytes) that communicate with other cells of the immune system, recruiting them to perform more aggressive roles in the fighting off of infection [..]

A substance secreted by cells of the immune system that stimulates growth/activity in a particular type of cell. Cytokines are produced locally (i.e. in the bone marrow) and circulate in the bloodstream. DEXA (Dual Photon X-ray Absorptionmetry) study

Protein molecules, released by cells when activated by antigen, that are involved in cell-to-cell communications, acting as enhancing mediators for immune responses through interaction with specific c [..]

Soluble factor produced by cells that has an effect on other cells.

Any of several regulatory proteins, such as interleukins and lymphokines, that are released by cells of the immune system and act as intercellular mediators in the generation of an immune response.
