October 2022 Identification of A2BAR as a potential target in colorectal cancer using novel fluorescent We selected the adenosine receptor 2B (A2BAR), specifically expressed in cancer cell lines compared with allowed semi-quantitative receptor mapping in living cells and validated the specific expression of A2BAR As well, fluorescent ligands were effective at monitoring real-time A2BAR receptor labeling using live-imaging Finally, we validated A2BAR as a potential pharmacological tool in CRC, using selective antagonists,

nanodiscs for 19 F-NMR and single-molecule fluorescence spectroscopy "We describe production of the human A2A adenosine receptor (A2AAR), a class A G protein-coupled receptor (GPCR) for 19F-NMR and single-molecule detail steps shared between the two sample preparation strategies, including expression and isolation of A2AAR and assembly of A2AAR in lipid nanodiscs and procedures for incorporation of either 19F-NMR or fluorescence

GPCR Agonist-to-Antagonist Conversion: Enabling the Design of Nucleoside Functional Switches for the A2A Adenosine Receptor "Modulators of the G protein-coupled A2A adenosine receptor (A2AAR) have been considered We synthesized and characterized a novel A2AAR antagonist, 2 (LJ-4517), with Ki = 18.3 nM. X-ray crystallographic structures of 2 in complex with two thermostabilized A2AAR constructs were solved The n-hexynyl group of 2 extends into an A2AAR exosite.

Agonist activation of the β2-adrenoceptor (β2AR) causes its S-nitrosylation that is required for the Eliminating β2AR S-nitrosylation by mutation of C265 augments β2AR protein kinase A signaling, enables β2AR nitric oxide (NO) signaling, renders mice resistant to bronchoconstriction, and protects mice from

in 2017 showed that Gs played a pivotal role in calcium signalling at the β2-adrenergic receptors (β2AR Overall, the increased calcium signalling was attributed to the release of ATP via β2AR-Gs mediated activation However, IP1 signalling through the non-cognate Gq was not important for the increased β2AR-Gs-mediated
