RESUMO
Recently,an unconventional T cell population (collectively designated as Vδ2 -γδT cell ) has been characterized during the anti-cytomegalovirus immune response in all organ transplant recipients,neo-nates,and healthy individuals.These cytomegalovirus-induced Vδ2 -γδT cells undergo a dramatic and stable ex-pansion after cytomegalovirus infection,in a conventional adaptive way.Similarly,as cytomegalovirus-specific CD8 +αβT cells,they exhibit an effector/memory TEMRA phenotype and cytotoxic effect or functions.This paper reviews the researchs and reports about cytomegalovirus induced-Vδ2 -γδT cell,including its location,phe-notype,and activation,as well as its immunologic mechanism in cytomegalovirus infection,acute or chronic re-jection,and anti-cancer function.
