clarify the molecular mechanisms governing ligand efficacy and potency at the β2 adrenergic receptor (β2AR Through an in-depth mutational analysis of β2AR, the researchers identified specific residues that influence By identifying key β2AR residues that influence efficacy and potency, pharmaceutical researchers can GPCRs, including β2AR, play key roles in various conditions, such as asthma, cardiovascular diseases, For instance, a patient with a specific variant of the β2AR gene that reduces potency might require a

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

These include EP2, EP4, A2AR, β1AR and β2AR, all of which promote T cell dysfunction.

< GPCR News < GPCRs in Oncology and Immunology A2aR on lung adenocarcinoma cells: A novel target for regulating tumor-associated macrophages Published date May 28, 2023 Abstract "Adenosine 2a receptor (A2aR Here, we identify that A2aR is specifically expressed on tumor cells from lung adenocarcinoma (LUAD) Notably, the M2 polarization of TAMs can also be prevented by inhibiting A2aR in vitro. blockade of A2aR may support a novel and potent therapeutic option for LUAD."
