Cytokines structure
WebThese are produced by bone marrow stromal cells, leukocytes and other cells, and stimulate the growth and differentiation of immature leukocytes. Therefore, in general, the cytokines of innate and adaptive immunity are produced by different cell populations and act on different target cells. WebInterleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system.It is a 15.5–16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity.IL-2 is part of the body's natural response to microbial infection, and in discriminating between foreign ("non-self") …

WebCytokines are proteins or glycoproteins which normally have a molecular mass of less than 30 KDa. 2. Structural predictions suggest that cytokines belong to … 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
