Proteins produced naturally in the body that act as “messengers” to initiate inflammatory and disease-fighting responses to viruses, bacteria, toxins, injury, and malignant processes. Cytokines are in use as anti-cancer medications.

-chemical messengers that allow neighbouring cells to communicate with each other. They are paracrine messages as distinct from endochrine or hormonal messengers. There are several main families of cytokines including growth factors , neurotransmitters, ,

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. ... (1...

Cytokines are messenger molecules produced by lymphocytes. They communicate with other cells of the immune system and recruit them to fight off infection or reject foreign tissue from the body.

Small proteins (in the range of 5-20 kD) released by cells and that affect the behaviour of other cells. Not really different from hormones, but the term tends to be used as a convenient generic shorthand for interleukins, lymphokines and several related signalling molecules such as TNF and interferons. Generally growth factors would not be classified as cytokines, though TGF is an exception. Rather an imprecise term, though in very common usage. Chemokines are a subset of cytokines; see Table C4a.

A group of proteins that occur naturally in the body and carry out a vital role as 'messengers' in the immune system. The blood cell growth factors G-CSF and GM-CSF are cytokines. They tell the bone marrow to make more blood cells.
