WebNov 18, 2024 · Cytotoxic T lymphocytes (CTLs) mediate apoptosis in tumor cells via a low level of perforin/granzyme release, consequently activating little gasdermin and producing a few pores on the cytoplasmic membrane [16, 17]. Notably, cells are capable of repairing perforin pore formation to a certain degree, protecting cells from pyroptosis .
