Splet01. nov. 2012 · The specific low pH of the LE is required for many virus infections, such as the influenza A virus and bunyavirus . Also, most adenovirus (Ad) serotypes enter cells by clathrin-mediated endocytosis, and then the pH inside the endosomes plays an essential role by inducing conformational changes in the viral particle. SpletMechanistically, upon entrance into the low pH of endosomes, HA1 is shed off of HA2 allowing it to undergo a gymnastic conformational change resulting in the insertion of HA2's fusion peptide into the endosomal lipid bilayer membrane, driving capsid entrance into the cytoplasm in a nontoxic manner (Staring et al. 2024). Thus, in our view, HA is ...
