| cytokines | Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialised glands. They generally act locally in a paracrine or autocrine rather than endocrine manner. (12 Dec 1998) |
