A soluble protein mediator, released by sensitized lymphocytes on contact with antigens, that plays a role in macrophage activation, lymphocyte transformation, and cell-mediated immunity.
A cytokine secreted by helper T cells in response to stimulation by antigens and that play a role in cell-mediated immunity.
Generic name for proteins that are released by lymphocytes to act on other cells involved in the immune response. The term includes interleukins and interferons. A sub-class of cytokines.

One of a group of compounds released by lymphocytes and causing a variety of stimulatory activity.
A class of soluble proteins, produced by white blood cells, that play a role in the immune response.
a chemical messenger (e.g., interferon, interleukin) produced by lymphocytes that directs and regulates immune responses by stimulating macrophages, killer cells and other lymphocytes.
a substance produced by LYMPHOCYTES to precipitate various immune reactions. Lymphokines include the INTERFERONS and INTERLEUKINS and are a subset of the CYTOKINE family.
