Salmonella effector SseL induces PD-L1 up-regulation and T cell inactivation via beta-catenin signalling axis

Umesh Chopra, Maria Kondooparambil Sabu, Raju S Rajmani…·Dipshikha Chakravortty

This study identifies Salmonella effector SseL as a key mediator of PD-L1 upregulation via beta-catenin signaling, leading to T cell inactivation and immune evasion.
