Soluble substances, released by sensitized lymphocytes on contact with specific antigens, that help effect cellular immunity by stimulating activity of monocytes and macrophages.
| Sports Science and Medicine: lymphokine |
A substance produced by lymphocytes involved in cell-mediated immune responses that play a part in the body's defence system.
| Veterinary Dictionary: lymphokine |
Soluble protein mediators released by lymphocytes undergoing blastogenesis following contact with antigen. Lymphokines influence the behavior of the cells that produce them (autocrine) and of other cells in the vicinity (paracrine) and cells at a distance (endocrine), including macrophages, neutrophils, lymphocytes and other cells; a subset of cytokines many of which are also defined as interleukins.

Lymphokines are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte. They are typically produced by T cells to direct the immune system response by signaling between its cells. Lymphokines have many roles, including the attraction of other immune cells, like macrophages and other lymphocytes, to an infected site and their subsequent activation prepare them to attack the invaders. Circulating lymphocytes can detect a very small concentration of lymphokine and then move up the concentration gradient towards where the immune response is required.
