Agonist-induced interaction of G protein-coupled receptors (GPCRs) with β-arrestins (βarrs) is a critical mechanism that regulates the spatiotemporal pattern of receptor localization and signaling. While the underlying mechanism governing GPCR-βarr interaction is primarily conserved and involves receptor activation and phosphorylation, there are several examples of receptor-specific fine-tuning of βarr-mediated functional outcomes. Considering the key contribution of conformational plasticity of βarrs in driving receptor-specific functional responses, it is important to develop novel sensors capable of reporting distinct βarr conformations in cellular context.

Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have gained prominence for their efficacy in treating type 2 diabetes and obesity. Recent evidence suggests that their pleiotropic effects-beyond glycemic control and weight loss-include anti-inflammatory, immunomodulatory, and antioxidative effects, which may beneficially support various dermatologic conditions such as psoriasis, hidradenitis suppurativa, acanthosis nigricans, and Hailey-Hailey disease. However, GLP-1 RAs are also associated with emerging cutaneous adverse drug reactions, including bullous, exanthematous and vasculitic manifestations, and other rare side effects.

Primary biliary cholangitis (PBC) is a rare disease for which management long consisted of a single treatment: ursodeoxycholic acid. In 2015-2016, this disease regained interest with the first studies on obeticholic acid (FXR agonist) and then on bezafibrate (PPAR agonist). Subsequently, over the past five years, significant progress has been made in the management of PBC.

Importance: The cardiovascular benefits of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) may vary by body mass index (BMI), but evidence on BMI-specific outcomes remains limited.
Objective: To investigate the associations of GLP-1 RA use with cardiovascular and kidney outcomes across BMI categories in patients with type 2 diabetes.
Design, Setting, And Participants: This retrospective cohort study used the Chang Gung Research Database, a clinical dataset covering multiple hospitals in Taiwan.
Objectives: Azapirone-class drugs are partial 5-HT1A receptor agonists commonly used to treat anxiety disorders. Prior experimental studies have so far demonstrated that these drugs have low potential for dependence and problematic use and are considered safe treatment options compared with benzodiazepines. However, recent evidence suggesting the contrary raises concerns about their safety.
