To investigate whether gBΔCTD2N735S is also able to drive gH/gL- or gD-independent viral entry, virus mutants simultaneously lacking the gB and gH (PrV-ΔgB/H), or gB and gD genes (PrV-ΔgB/D) (35), were complemented in trans with gBΔCTD2N735S and used for infection experiments (Fig. 2B). Here, PAEP is linked to infection.
