WebApr 6, 2024 · The six major cytokine receptor families are type I cytokine receptors, type II cytokine receptors, TNF receptors, IL-1 receptors, tyrosine kinase receptors, and … 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, allowing for exceptions, are obsolete. The term … See more 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 … 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 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.

WebThe functional classification of the cytokines divides it into two types: Type 1 includes TNFα, IFN-γ, etc., which enhance cellular immune responses. Type 2 includes IL-4, IL-10, TGF-β, IL-13, etc., which enhance antibody responses. Function of Cytokines Cytokines are majorly produced by helper T cells and macrophages. Webthe release of one cytokine leads to the production and secretion of a series of others, resulting in either positive or negative feedback pathways. Classification of cytokines, in general, has been arbitrary depending upon the individual author. Cytokines have been grouped based on either their cell sources, their effects on cells, or their ...
WebFeb 20, 2008 · The classification of cytokine family was done at first by using the dipeptide composition alone (Table II). The dipeptide-based cytokine family classification achieved an overall accuracy of 96.34% and an average MCC of 0.95. The classification was done by using the hybrid approach. WebClassification of Cytokines. Based on their actions, cytokines can be classified as follows: Chemokines are a class of cytokines that cause the cells to migrate along a chemical gradient. When the macrophages release chemokines, the cells migrate through chemotaxis and move towards the region where the concentration of chemokines is the highest ...
