Cytokines

Info

Cytokines are signaling proteins in cellular communication.
While hormones are secreted from specific organs to the blood, and neurotransmitters are related to neural activity, the cytokines are a more diverse class of compounds in terms of origin and purpose. They are produced by a wide variety of hematopoietic and non-hematopoietic cell types and can have autocrine, paracrine and endocrine effects, sometimes strongly dependent on the presence of other chemicals. The cytokine family consists mainly of smaller, water-soluble proteins and glycoproteins with a mass between 8 and 30 kDa.

The term cytokine is used generically for interleukins, chemokines, growth factors, neurotrophins and similar extracellular proteinaceous ligands (lymphokines, monokines, interferons, colony-stimulating factors, immunomodulators, immunotransmitters, etc.).

Cytokines can be isolated from natural sources or are recombinant and produced in bacteria, yeast or higher eukaryotic cells. Wheras bacterially expressed ones lack post-translational modifications, the latter are glycoproteins. In many assays non-glycosylated cytokines show a similar activity as glycosylated ones, for some studies glycosylation is important.
