In contrast, Wamsom et al. [32] who compared CD4+, CD8+, CD4+/CD8+, and FoxP3 T cell subsets have not found any correlation of the levels of these T cells types in the peripheral blood and in the tumor microenvironment between HPV-positive and HPV-negative head and neck tumors. The gene discussed is CD8A; the disease is head and neck neoplasm.
