Abstract Cytopathic bovine viral diarrhoea virus (cp BVDV) induces apoptosis in bovine cell cultures. This also seems to be a prominent feature in the pathogenesis of mucosal disease. To gain an insight into the molecular pathways of the cell alterations, the involvement of different members of the apoptotic cascade was analyzed. It was shown that inhibition of the mitochondrial permeability transition pore significantly delayed the cytopathic effect without affecting virus replication. Moreover, the membrane potential (deltapsi(m)) was affected, and translocation of cytochrome c to the cytosol, overexpression of apoptotic protease-activating factor 1 and a significant increase of caspase-9 activity were demonstrated, indicating that the apoptosome is formed. We conclude that at least in vitro, infection of cells with cp BVDV leads to the activation of the intrinsic pathway of apoptosis.
