Cytokines & Chemokines Flashcards Quizlet
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 WebThe chemokines (or chemotactic cytokines) are a large family of small, secreted proteins that signal through cell surface G protein-coupled heptahelical chemokine receptors. They are best known for their ability to stimulate the migration of cells, most notably white blood cells (leukocytes). Consequently, chemokines play a central role in the ... how to level up flyers speed in ark
