[ad_1] In thiol-mediated uptake, dynamic covalent exchange with thiols at the cell surface precedes entry by different mechanisms. The inhibition of thiol-mediated absorption by elimination of exofacial thiols could thus allow new antivirals. Credit: © UNIGE / MATILE Some viruses can enter cells via a mechanism involving organic sulfur molecules. UNIGE chemists have discovered effective … Read more
