Why Do Tumors Hide From the Immune System?

This documentary investigates how tumors can make immune attack less effective. It examines impaired antigen presentation, PD-L1 expression, altered innate immune signaling, lactate, STING, and immune-cell infiltration across specific experimental models. The film examines what researchers know from in-vitro studies, animal models, and review evidence—and what remains unanswered about targeting these mechanisms together in patients.
