cytokine meaning

  • Cytokines (Greek:Cyto from Greek "κύτταρο" kyttaro "cell" + Kines from Greek "κίνηση" kinisi "movement") are a broad and loose category of small proteins (~5–20 kDa) that are important in cell signaling.
  • They act through receptors, and are especially important in the immune system; cytokines modulate the balance between humoral and cell-based immune responses, and they regulate the maturation, growth, and responsiveness of particular cell populations.
  • They are different from hormones, which are also important cell signaling molecules, in that hormones circulate in much lower concentrations and hormones tend to be made by specific kinds of cells.
