Bacteriocins are ribosomally-synthesized antimicrobial peptides, showing great potential as novel treatment options for multidrug-resistant pathogens. In this study, we designed a novel hybrid bacteriocin, Hybrid 1 (H1), by combing the N-terminal part and the C-terminal part of the related bacteriocins

Purinergic receptors and NOD-like receptor protein 3 (NLRP3) inflammasome regulate inflammation and viral infection, but their effects on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection remain poorly understood. Here, we report that the purinergic receptor P2X7 and NLRP3 inflammasome

We have characterized PPADS (pyridoxalphosphate-6-azophenyl-2',4'-disulfonic acid) as a novel antagonist which selectively blocks P2 purinoceptor-mediated responses in rabbit vas deferens at pre- and postjunctional sites. PPADS did not interact with alpha 1-adrenoceptors, muscarinic M2 and M3 receptors, histamine H1 and
