Members of the picornavirus family, including poliovirus and foot-and-mouth disease virus, are widespread pathogens of humans and domestic animals. Recent global developments in the resurgence of poliovirus infection and in the control of foot-and-mouth disease infection highlight the problems caused by the ability of picornaviruses to alter the apoptotic machinery of host cells and establish persistent infections. Despite the medical, economic and social impact of this family of viruses, little information exists that integrates the mechanisms of cell death and damage induced by related family members. Fortunately, examination of the reported roles and functions of individual viral proteins from multiple picornaviruses makes it possible to surmise canonical functions for these proteins. This review analyzes the canonical function of picornavirus proteins involved in the alteration of apoptotic homeostasis in infected host cells.
