Background: Monovalent biologics blocking thymic stromal lymphopoietin or interleukin-13 have been shown to elicit pharmacodynamic responses in asthma following a single dose. Therefore, dual blockade of these cytokines may result in an enhanced response compared to single targeting and has the potential to break efficacy ceilings in asthma. This study assessed the safety and tolerability of lunsekimig, a bispecific NANOBODY molecule that blocks thymic stromal lymphopoietin and interleukin-13, and its effect on Type 2 inflammatory biomarkers and lung function in asthma.

Background: Current guidelines recommend transcatheter aortic valve implantation (TAVI) for patients with aortic stenosis and porcelain aorta (PA). Neurological outcomes of patients with PA undergoing TAVI with modern valves require clarification as most trials examined balloon-expandable valves (BEV) and self-expandable valves in intermediate or high-risk patients, but not specifically in patients with PA. Our aim was to compare outcomes, including stroke and mortality, in well-matched patients with and without PA who received BEV during transfemoral TAVI procedures.

Androgens, such as 5α-dihydrotestosterone (5α-DHT), regulate numerous functions by binding to nuclear androgen receptors (ARs) and potential unknown membrane receptors. Here, we report that the androgen 5α-DHT activates membrane receptor GPR133 in muscle cells, thereby increasing intracellular cyclic AMP (cAMP) levels and enhancing muscle strength. Further cryoelectron microscopy (cryo-EM) structural analysis of GPR133-Gs in complex with 5α-DHT or its derivative methenolone (MET) reveals the structural basis for androgen recognition.
