Impairment of the M-protein and unmasking of a superficial type-specific antigen by proteolytic treatment of influenza A virions with preservation of host-specific antigenicity.

abstract：BACKGROUND:Herpesviridae encode a family of protein homologues that function as the 'port of entry' for insertion of the viral DNA into preformed capsids during encapsidation. METHODS:Transmission electron microscopy (TEM) of recombinant varicella-zoster virus pORF54 was performed. RESULTS:Results suggest that pORF54...
