Viral subversion of apoptosis regulation plays an important role in the outcome of host⁄virus interactions. Although human cytomegalovirus (HCMV) encodes several immediate early (IE) antiapoptotic proteins (IE1, IE2, vMIA and vICA), no proapoptotic HCMV protein has yet been iden-tified. Here we show that US28, a functional IE HCMV-encoded chemo-kine receptor, which may be involved in both viral dissemination and immune evasion, constitutively induces apoptosis in several cell types.
