Stenocytosis: a mechanism for supramolecular attack particle transfer at the CTL lytic synapse

Lucie Demeersseman, Claudia Schirra, Ute Becherer…·Salvatore Valitutti

The paper describes stenocytosis, a mechanism by which CTLs transfer supramolecular attack particles into target cells through narrow actin gaps.

Perforin-mediated pore formation at the lytic synapse triggers the canonical pyroptotic cell death pathway

Brienne McKenzie, Marie-Pierre Puisségur, Lucie Demeersseman…·Salvatore Valitutti

This study shows perforin triggers pyroptosis in target cells by activating the NLRP3/caspase-1/gasdermin D pathway, while sustained CTL interaction leads to apoptosis.
