Task: Answer Verification
Input (English): Question: Does b7-H4 overexpression impair the immune response of T cells in human cervical carcinomas?
Answer: B7-H4 is overexpressed in human cervical cancers, and it is associated with lower numbers of tumor-infiltrating CD8(+)T lymphocytes and therefore less IFN-γ production. In vitro, B7-H4 inhibits the proliferation of CD4(+)T and CD8(+)T but promotes the proliferation of Tregs and the secretion of IL-10 and TGF-β1. B7-H4 plays an important role in depressing the anti-tumor immunity of CD8(+)T cell in microenvironments of cervical cancer.
Output (English): yes
