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

Lymphokine
Lymphokine sind eine Sammelbezeichnung für spezielle Zytokine. Die ursprüngliche Definition von Dumonde (1982) bezeichnete alle nicht-Antikörper-Proteine, die von aktivierten Lymphozyten produziert werden und als interzellulare Botenstoffe der Immunantwort wirken, als Lymphokine. Diese Definition ist in mehrerer Hinsicht problematisch und wird seit den 1990er-Jahren kaum noch verwendet.
