Cytokines

Overview
  • Cytokines are proteinacious molecules secreted by immune and non-immune cells which help coordinate immune and inflammatory responses. Cytokines may act on the secreting cell itself, act locally on other cells within a region of inflammation, or exert their effects at distant locations. In general, cytokines are used as molecular communication signals between cells for the purpose of mounting an effective and coordinated immune or inflammatory response. Below we individually discuss some of the key mammalian cytokines.
