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.
