In this study, for the first time we show that BoHV-1 infection manipulated phospholipase C (PLC) signaling, as demonstrated by the activation of PLCγ-1 at both early stages [at 0.5 h post-infection (hpi)] and late stages (4–12 hpi) during the virus infection of MDBK cells. Here, HSPG2 is linked to infection.
