cytokines

Cytokines are small proteins that regulate and mediate immunity, inflammation, and hemotopoiesis.

Cytokines are secreted de novo in response to immune stimuli, and usually act briefly, locally, at very low concentrations (the exception being endocrine action at distant cells). Cytokines bind to specific membrane receptors, which then signal the cell via second messengers, often tyrosine kinases, to alter cellular activity (gene expression).
