Cytokines: sources, receptors and signalling - PubMed
WebApr 6, 2024 · The mechanism of cytokinesis is to “modulate inflammatory responses by shifting from Th1, proinflammatory cascades, to Th2, anti-inflammatory healing cascades … Cytokines are a broad and loose category of small proteins (~5–25 kDa ) 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. … See more Interferon-alpha, an interferon type I, was identified in 1957 as a protein that interfered with viral replication. The activity of interferon-gamma (the sole member of the interferon type II class) was described in 1965; this was … See more Cytokines have been classed as lymphokines, interleukins, and chemokines, based on their presumed function, cell of secretion, or target of action. Because cytokines are … See more In recent years, the cytokine receptors have come to demand the attention of more investigators than cytokines themselves, partly because of their remarkable … See more Cytokines are involved in several developmental processes during embryonic development.
