Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
During this time, the demand is high for sphingomyelin, which is made from phosphatidylcholine (and thus from choline), because this material is used to myelinate (insulate) nerve fibers. [39] Choline is also in demand for the production of the neurotransmitter acetylcholine, which can influence the structure and organization of brain regions ...
Phosphatidylinositol 4,5-bisphosphate or PtdIns(4,5)P 2, also known simply as PIP 2 or PI(4,5)P 2, is a minor phospholipid component of cell membranes. PtdIns(4,5)P 2 is enriched at the plasma membrane where it is a substrate for a number of important signaling proteins. [1] PIP2 also forms lipid clusters [2] that sort proteins. [3] [4] [5]
1-Oleoyl-2-palmitoyl-phosphatidylcholine. Phosphatidylcholines (PC) are a class of phospholipids that incorporate choline as a headgroup.They are a major component of biological membranes and can easily be obtained from a variety of readily available sources, such as egg yolk or soybeans, from which they are mechanically or chemically extracted using hexane.
Neuropathy target esterase is a phospholipase that deacetylates intracellular phosphatidylcholine to produce glycerophosphocholine. It is thought to function in neurite outgrowth and process elongation during neuronal differentiation. The protein is anchored to the cytoplasmic face of the endoplasmic reticulum in both neurons and non-neuronal ...
Enzymes having phospholipase B activity hydrolyze both the sn-1 and sn-2 positions, so they produce both 1-lysoPC and 2-lysoPC. In humans, a number of enzymes with phospholipase A1 exist: they include two from the brain (with different optimal pHs), two from the liver (one cytosomal and one membrane-bound) [4] and one from the mitochondrion. [5]
Activity-dependent plasticity is a form of functional and structural neuroplasticity that arises from the use of cognitive functions and personal experience. [ 1 ] Hence, it is the biological basis for learning and the formation of new memories .
In the human brain microvascular endothelial cells, two systems initiate the choline absorption. The first system is known as the Choline transporter-like protein 1, or CTL1. The second system is the Choline transporter-like protein 2, or CTL2. Those two systems are found on the plasma membrane of the brain microvascular endothelial cells.
