2021-09-23
The differential tissue- and ligand-dependent signaling described here has important implications for the therapeutic potential of synthetic GPR109A agonists for the treatment of atherosclerosis. The failure of MK-0354, a biased, partial GPR109A agonist, to activate signaling pathways upstream of va

Animal models of NASH The human NAS system (see above) is largely reproducible in NAFLD mouse models [37] and, therefore, has been increasingly applied in the preclinical assessment of liver histological responses to test compounds. In general, the NAS system is well suited for this purpose, alth

Selective pharmacological inhibition of tonic currents indicated that the effects of gp120 are predominantly mediated by α5-containing GABAARs. The other dominant subtype that contributes to tonic current in the hippocampus, the δ-containing GABAAR, was unaffected by gp120 treatment. Additionally, i

Ironically, another series of studies examining the role of EAATs in CNS injury and disease suggest that under some pathological conditions, the operation of the EAATs is not protective, but actually contributes to the excitotoxic process (Rossi et al., 2000). The transporters do so by serving as th

The LBD experiences a large-scale conformational transition between open and closed states upon agonist binding within the cleft separating the two lobes of the domain. The upper lobe (Lobe 1, also called D1) is connected to the ATD, and the lower lobe (Lobe 2, also called D2) is connected to the TM

In summary, our findings provide the evidence and the mechanistic understanding of the protective effects of GIP receptor agonist, D-Ala2GIP, in the MPTP-induced neurotoxicity in mice. The observed protective effects are potentially due to reduced oxidative stress and attenuation of dopamine loss in

During cardiac ischaemia, a decrease in GJ coupling is observed, which results in slower conduction of electrical impulses and a higher risk of arrhythmias.[13], [20] In Huntington’s disease an increase in the Piperine of 5 Cxs was observed in the astrocytes in the brain, suggesting an adaptive pr

Biologically active non-peptide galanin receptor ligands The first successful attempt in overcoming these weaknesses was undertaken by Saar et al. (2002). Screening of galanin sequence established that Trp-2, Asn-5, Tyr-9 were pharmacophores, responsible for biochemical action of the peptide. Bas

Fatty acids are also known to activate G-protein coupled receptors (GPCRs). LCFAs activate the GPCRs for free fatty Doripenem (FFA)1 and FFA4 (Briscoe et al., 2003; Hirasawa et al., 2005), whereas SCFAs activate FFA2 and FFA3 receptors, which are expressed in bovine neutrophils (Alarcon et al., 201

Recent research has focused on identifying key agonists and receptors mediating nutrient-induced GLP-1 and insulin secretion. The long-chain fatty mechlorethamine receptor GPR40 is the most abundant GPCR expressed in islet β cells and is also expressed on intestinal L-cells, where it contributes to

Our data show that oxidative stress (high levels of ROS) suppresses the process of lysosomal exocytosis, which would be predicted to impair the expulsion of toxic compounds from cells. Therefore, we propose that ROS have a biphasic effect on the lysosomal clearance: consistent with their role as a s

2021-09-22
In NAFLD models, the “first hit” is liver fat accumulation, which causes insulin resistance, whereas the interplay of inflammatory cytokines, which causes inflammation, acts as the representative “second hit” [9]. However, recently, the “multiple hit” hypothesis has taken into consideration that mul
