Transient receptor potential channels (TRP channels) are a group of ion channels located mostly on the plasma membrane of numerous animal cell types. Most of these are grouped into two broad groups: Group 1 includes TRPC ( "C" for canonical), TRPV ("V" for vanilloid), TRPVL ("VL" for vanilloid-like), TRPM ("M" for melastatin), TRPS ("S" for soromelastatin), TRPN ("N" for mechanoreceptor ...
Notch-mediated juxtacrine signal between adjacent cells Notch signaling steps. The Notch signaling pathway is a highly conserved cell signaling system present in most animals. [1] Mammals possess four different notch receptors, referred to as NOTCH1, NOTCH2, NOTCH3, and NOTCH4. [2] The notch receptor is a single-pass transmembrane receptor protein.
The name "NMDA receptor" is derived from the ligand N-methyl-D-aspartate (NMDA), which acts as a selective agonist at these receptors. When the NMDA receptor is activated by the binding of two co-agonists, the cation channel opens, allowing Na + and Ca 2+ to flow into the cell, in turn raising the cell's electric potential. Thus, the NMDA ...
Ryanodine receptors (RyR for short) form a class of intracellular calcium channels in various forms of excitable animal tissue like muscles and neurons. [1] There are three major isoforms of the ryanodine receptor, which are found in different tissues and participate in different signaling pathways involving calcium release from intracellular organelles.
Aquaporin 2 is regulated by vasopressin which, when bound to the cell-surface receptor, activates the cAMP signaling pathway. This results in aquaporin-2 containing vesicles to increase water uptake and return to circulation. Mutation of the aquaporin 2 vasopressin receptor is a cause of acquired diabetes insipidus.
In recent years, many small molecules, such as azaserine, acivicin, and CB-839 have been shown to inhibit glutaminase, thus reducing cancer cell viability and inducing apoptosis in cancer cells. [24] Due to its effective antitumor ability in several cancer types such as ovarian, breast and lung cancers, CB-839 is the only GLS inhibitor ...
The first attempt to purify the receptor involved the use of a novel opioid antagonist called chlornaltrexamine that was demonstrated to bind to the opioid receptor. [10] Caruso later purified the detergent-extracted component of rat brain membrane that eluted with the specifically bound 3 H -chlornaltrexamine.
Diagram of a chemical synaptic connection. In the nervous system, a synapse [1] is a structure that allows a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or a target effector cell.
