1607-Spatial Immune Resistance in Oropharyngeal Cancer
These researchers utilized single-cell spatial gene expression profiling and RNA sequencing to map the cellular landscape of human papilloma virus-related oropharyngeal cancer (HPV-OPSCC). The study identifies distinct immune foci within the tumor, revealing that different regions use unique methods of immunosuppression, such as hypoxia or T cell exhaustion, to evade the body's natural defenses. A significant discovery is the presence of HPVoff cells, which are cancer cells that stop expressing viral genes and enter a senescent-like state to survive. Findings suggest that IFN-γ signaling and…
