Alterations in the expression and/or activity of brain G-protein-coupled receptors (GPCRs) such as dopamine Since studies have indicated that flavonoids can target brain GPCRs and provide neuroprotection via inhibition Functional GPCR assays unfolded the compound's antagonist behavior on D1R (IC50 42.1 ± 0.35 μM) and agonist

Several neurotransmitters and neuromodulators, acting through G-protein-coupled receptors (GPCRs), fine-tune However, intracellular partners linking GPCRs to TASK1 modulation are not yet well-known. We hypothesized that isoform 2 of rho-kinase (ROCK2), acting as downstream GPCRs, mediates adjustment Furthermore, ROCK activity assays were performed to evaluate the ability of various physiological GPCR

There are only two drugs in the market targeting chemokine receptors: maraviroc, an allosteric and reversible Further difficulties arise from the existence of cross-reactivity with other GPCRs and differences in of chemokine receptors which are regulated by globular protein ligands, unlike most of the class A GPCRs et al. 2009; Wang and Norcross 2008); and are also too small to be engaged by antibodies, which can only
