WebJan 1, 1989 · There are three pairs of cytokines, IL-1a/ TNFa/and interferon (IFN)a/ in which the members of the pair are about 30% homologous at the amino kid level, can bind to the same cell-surface receptor and are likely to have arisen by gene duplication. The genes encoding these pairs are also tightly linked (Table 2). WebCytokines are a family of protein mediators that are important in transducing information between various cell types. These messengers are synthesized by a broad spectrum of cells. Cellular sources of cytokines include those cell types considered to play pivotal roles in the immune system as well as … Cytokines: sources, receptors and signalling
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 … 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 characterised by considerable redundancy and pleiotropism, such distinctions, … 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. Cytokines are released from the blastocyst, and are also expressed in the See more Classic hormones circulate in aqueous solution in nanomolar (10 M) concentrations that usually vary by less than one order of magnitude. In contrast, some cytokines (such as IL-6) circulate in picomolar (10 M) concentrations that can increase up to … See more Structural Structural homogeneity has been able to partially distinguish between cytokines that do not demonstrate a considerable degree of redundancy so that they can be classified into four types: • The … See more Each cytokine has a matching cell-surface receptor. Subsequent cascades of intracellular signaling then alter cell functions. This may include the upregulation and/or downregulation of several genes and their transcription factors, resulting in the … See more WebCytokines refer to a large group of cell-signaling molecules that essentially consists of proteins, peptides, and glycoproteins. They either have short or long chain structures. …
