Cancer cells have developed a mechanism to repress T cell response to neoantigens. Present a method that would allow restoration of the T cell response when the response is halted at a checkpoint
What will be an ideal response?
To restore T cell function when the response is halted at a checkpoint, one would design a checkpoint inhibitor. This will prevent the cancer cell from suppressing the T cell response at the checkpoint.
