Differential expression of immune-related genes in HPV-positive and HPV-negative OPSCC. (A) Volcano plot depicting significantly increased (right) or decreased (left) expression of immune-related genes in HPV-positive OPSCC. (B) Differential expression of predefined pathway genes and (C) gene expression-based cell types in HPV-positive and HPV-negative OPSCC. Significantly different data are represented by *p < 0.05, **p < 0.01, ***p < 0.001 and ****p < 0.0001
