Autocrine signaling involves a cell secreting a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell itself. [13] This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell. [1] This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events.Proteins responsible for detecting stimuli are generally termed receptors, although in some cases the term sensor is used. [1]
Common lipid signaling molecules: lysophosphatidic acid (LPA) sphingosine-1-phosphate (S1P) platelet activating factor (PAF) anandamide or arachidonoyl ethanolamine (AEA). Lipid signaling, broadly defined, refers to any biological cell signaling event involving a lipid messenger that binds a protein target, such as a receptor, kinase or phosphatase, which in turn mediate the effects of these ...
Interferon-alpha, an interferon type I, was identified in 1957 as a protein that interfered with viral replication. [5] The activity of interferon-gamma (the sole member of the interferon type II class) was described in 1965; this was the first identified lymphocyte-derived mediator. [6]
Autocrine signaling is a form of signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on the same cell, leading to changes in the cells.
TGF" (Transforming Growth Factor) is a family of proteins that includes 33 members that encode dimeric, secreted polypeptides that regulate development. [37] Many developmental processes are under its control including gastrulation, axis symmetry of the body, organ morphogenesis, and tissue homeostasis in adults. [ 38 ]
Glutamate is a very major constituent of a wide variety of proteins; consequently it is one of the most abundant amino acids in the human body. [1] Glutamate is formally classified as a non-essential amino acid, because it can be synthesized (in sufficient quantities for health) from α-ketoglutaric acid, which is produced as part of the citric acid cycle by a series of reactions whose ...
