2-aminoethoxydiphenyl borate is a common activator of TRPV1, TRPV2, and TRPV3.
The transient receptor potential (TRP) superfamily contains a large number of proteins encoding cation permeable channels that are further divided into TRPC (canonical), TRPM (melastatin), and TRPV (vanilloid) subfamilies. Among the six TRPV members, TRPV1, TRPV2, TRPV3, and TRPV4 form heat-activated cation channels, which serve diverse functions ranging from nociception to osmolality regulatio...
متن کاملNicotinic Acid is a Common Regulator of Heat-Sensing TRPV1-4 Ion Channels
Nicotinic acid (NA, a.k.a. vitamin B3 or niacin) can reduce blood cholesterol and low-density lipoproteins whereas increase high-density lipoproteins. However, when NA is used to treat dyslipidemias, it causes a strong side effect of cutaneous vasodilation, commonly called flushing. A recent study showed that NA may cause flushing by lowering activation threshold temperature of the heat-sensiti...
متن کاملConserved residues within the putative S4-S5 region serve distinct functions among thermosensitive vanilloid transient receptor potential (TRPV) channels.
The vanilloid transient receptor potential channel TRPV1 is a tetrameric six-transmembrane segment (S1-S6) channel that can be synergistically activated by various proalgesic agents such as capsaicin, protons, heat, or highly depolarizing voltages, and also by 2-aminoethoxydiphenyl borate (2-APB), a common activator of the related thermally gated vanilloid TRP channels TRPV1, TRPV2, and TRPV3. ...
متن کاملPharmacological characterization and molecular determinants of the activation of transient receptor potential V2 channel orthologs by 2-aminoethoxydiphenyl borate.
Despite its expression in different cell types, transient receptor potential V2 (TRPV2) is still the most cryptic members of the TRPV channel family. 2-Aminoethoxydiphenyl borate (2APB) has been shown to be a common activator of TRPV1, TRPV2, and TRPV3, but 2APB-triggered TRPV2 activation remains to be thoroughly characterized. In this study, we have developed an assay based on cell lines stabl...
متن کامل2-Aminoethoxydiphenyl borate reduces degranulation and release of cytokines in a rat mast cell line.
BACKGROUND AND OBJECTIVE 2-aminoethoxydiphenyl borate (2-APB) has been reported to be a useful pharmacological tool in the study of calcium signaling. It is used either as a membrane-permeable inhibitor for inositol 1,4,5-trisphosphate (IP3) receptors or a store-operated calcium (Ca2+) entry (SOCE) inhibitor. The present study aimed to evaluate the effects of 2-APB on degranulation and cytokine...
