WebbBesides their trophic functions supporting angiogenesis, invasion, and metastasis, TAMs have also been suggested to inhibit T cell proliferation and activation by various mechanisms. WebbWhile PD1-mediated T cell inhibition is an important mechanism to prevent autoimmunity, cancer and chronic infectious diseases may usurp this regulation mechanism to drive immune suppression ( 2 ). In fact, the PD1-PD-L1 axis is one of the major axis used by a variety of cancer types to inhibit T cell responses and function ( 3 ).
