FOXP4-AS1 promotes CD8 T cell exhaustion and esophageal cancer immune escape through USP10-stabilized PD-L1.

Esophageal cancer (EC) is the 9th most frequently diagnosed malignancy globally with unfavorable prognosis. Immune escape is one of the principal factors leading to poor survival, however, the mechanism underlying immune escape remains largely uninvestigated. The xenograft mouse model and EC cell-CD8 cytotoxic T lymphocytes (CTLs) co-culture system were established.
