WebCytokines are a broad and loose category of small proteins (~5–25 kDa [1]) important in cell signaling. Cytokines are peptides and cannot cross the lipid bilayer of cells to enter the cytoplasm. Cytokines have been shown to be involved in autocrine, paracrine and endocrine signaling as immunomodulating agents. Web• Chemical Structure • Physiological Action • Transport.
