Reovirus infection of target cells can perturb cell cycle regulation and induce apoptosis. Differences in the capacity of reovirus strains to induce cell cycle arrest at G1 and G2/M have been mapped to the viral S1 genome segment, which also determines differences in the ability of reovirus strains to induce apoptosis and to activate specific mitogen-activated protein kinase (MAPK) cascades selectively. Reovirus-induced apoptosis involves members of the tumor necrosis factor (TNF) superfamily of death receptors and is associated with activation of both death receptor-and mitochondrial-associated caspases. Reovirus infection is also associated with the activation of a variety of transcription factors, including nuclear factor (NF)-kappaB. Junctional adhesion molecule (JAM) has recently been identified as a novel reovirus receptor. Reovirus binding to JAM appears to be required for induction of apoptosis and activation of NF-kappaB, although the precise cellular pathways involved have not yet been identified.
