- Moffitt’s preclinical findings strongly suggest PV-10 induces immunogenic cell death-associated immunogenicity in HPV-positive and HPV-negative HNSCC in vitro and in vivo
The abstract, which was accepted for a poster presentation, is titled “PV 10 induces endoplasmic reticulum stress and autophagy, triggering immunogenic cell death and anti-tumor immunity in head and neck squamous cell carcinoma” (Abstract #6742, Topic Track: Immunology, Session: Vaccines, Antigens, and Antigen Presentation 2).
The work underlying this poster presentation is part of research conducted by
According to Moffitt’s abstract, “…in vitro findings reveal that PV-10 induces cytotoxicity in both mEER and MTE-RAS cells. Notably, PV-10 promotes a significant increase in [reactive oxygen species], leading to an elevation in late apoptotic cells. Markers of immunogenic cell death (ICD), including a statistically significant increase in the release of damage-associated molecular pattern molecules HMGB1 and ATP, as well as enhanced surface expression of calreticulin, HSP-70, and HSP-90, were observed. At the molecular level, a remarkable activation of endoplasmic reticulum (ER) stress, pro-apoptotic protein, and autophagy markers were observed. Intratumoral PV-10 injection in vivo has shown significant tumor regression in both mEER and MTE-RAS tumors, and a complete response was noticed in some mice, indicating that PV-10 induces potent ICD in both mEER and MTE-RAS tumors.”
