Cytokines families
The four-α-helix bundle family (InterPro: IPR009079): member cytokines have three-dimensional structures with a bundle of four α-helices. This family, in turn, is divided into three sub-families: the IL-2 subfamily. This is the largest family. It contains several non-immunological cytokines including erythropoietin (EPO) and … 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 … 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 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 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 characteristics and partly because a deficiency of cytokine receptors has now been … See more WebCytokines are proteins that mediate the effector functions of the immune system. They can act in several different ways: -Endocrine: cytokines pass through bloodstream (similar to hormones) to signal. -Paracrine: cytokines act on nearby cells via immunological synapses (short distance). -Autocrine: cytokines act on self (same cell).

Cytokine … WebApr 16, 2024 · There are multiple families of cytokines, but in this review, we will focus on one family of type I four α-helical bundle cytokines known as the common cytokine receptor γ chain (γ c) family of cytokines, which includes interleukins 2, 4, 7, 9, 15, and 21; the basis for this family is that each of these cytokines shares γ c as a receptor …
WebCytokines of the IL6/GCSF/MGF family are glycoproteins of about 170 to 180 amino acid residues that contain four conserved cysteine residues involved in two disulphide bonds. [22] They have a compact, globular fold (similar to other interleukins), stabilised by the two disulphide bonds. WebCytokines are a category of signaling molecules that mediate and regulate immunity, inflammation and hematopoiesis. Cytokines are produced throughout the body by cells of diverse embryological origin. Cytokine is a general name; other names are defined based on their presumed function, cell of secretion, or target of action.

WebInterleukin-1 family. The IL-1 family comprises 11 cytokines that regulate multiple phases of both the innate and adaptive immune responses. IL-1α and IL-1β are the best-studied members and were initially characterized as endogenous pyrogens [ 64 ]. Activated neutrophils, monocytes, and macrophages are important sources of IL-1 family members.
