The study examines the role of HPK1 and its inhibition in CD8 TILs within gynecologic malignancies.
Isolated tumor-infiltrating CD8 T cells from patients with endometrial (n=53) and ovarian cancer (n=46)
Examined HPK1 signaling in CD8 TILs using flow cytometry
Stimulated TILs with anti-CD3 in the presence of FB849 and/or anti-PD-1
Assessed proliferation and effector function of CD8 TILs
HPK1 marks severely exhausted PD-1+CD8 TILs
High HPK1 expression correlated with increased exhausted PD-1+CD8 TILs
FB849 restored effector function of exhausted CD8 TILs
FB849 further enhanced anti-PD-1-mediated reinvigoration in endometrial cancer

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Experiments using the kinase inhibitor FB849 show improved T cell function in endometrial and ovarian cancers, indicating potential for immunotherapy.
