摘要：Gene engineering and combinatorial approaches with other cancer immunotherapy agents may confer capabilities enabling full tumor rejection by adoptive T cell therapy(ACT).The provision of proper costimulatory receptor activity and cytokine stimuli,along with the repression of inhibitory mechanisms,will conceivably make the most of these treatment *** this sense,T cells can be genetically manipulated to become refractory to suppressive mechanisms and exhaustion,last longer and differentiate into memory T cells while endowed with the ability to traffic to malignant *** antitumor effects can be dramatically augmented with permanent or transient gene transfer maneuvers to express or delete/repress genes.A combination of such interventions seeks the creation of the ultimate bionic T cell,perfected to seek and destroy cancer cells upon systemic or local intratumor delivery.
