Perforin is part of the cytotoxic effector mechanism of CD8+ T cells. Here the authors show that antigen-induced perforin release from CD8 T cells into antigen-presenting cells can activate NLRP3 inflammasome to constitute a positive feedback loop to promote anti-tumour immunity and allo-responses.
