Increased expression of PD ‑L1 by the human papillomavirus 16 E7 oncoprotein inhibits anticancer immunity.

In conclusion, the results presented in the current study suggest that overexpression of PD‑L1, induced by HPV16E7, may be responsible for lymphocyte dysfunction. In addition, soluble PD‑1 may restore the function of tumor‑infiltrating lymphocytes by inhibiting the PD‑L1/PD‑1 signaling pathway. These results may provide a novel insight for immunotherapeutic approaches in the treatment of cervical cancer. PMID: 28075442 [PubMed - as supplied by publisher]
