 In non-enveloped viruses, the membrane permeability changes may be sufficient to induce cell lysis, thereby permitting the new virions to exit the cell.In enveloped viruses, viroporins' depolarization effect is thought to promote viral budding.Abrogating the ion channel or pore function of viroporins, either through mutations that block conductance without disrupting other functions or through channel-blocking drugs, usually reduces or eliminates viral propagation.
