the latter effect could be obtained by ( i ) covering of the penton bases , as performed by anti-penton base antibodies , thereby preventing interaction between the penton bases and the endosomal membrane , which results in trapping of virions within endosomes , and ( ii ) inhibition of the low-ph-induced conformational change of the viral capsid , which seems to occur in the endosomes and is necessary for proper exposure of the penton bases , as performed by anti-hexon antibodies .
