the main bit is this ......... Th1 ..... "pro inflammatory"
Neoantigen vaccination strategies in murine models suggest that CD4+ responses to neoantigens are more prevalent and potentially more effective in antitumor immunity than CD8+ T-cell responses (15). A global analysis of immune subsets in a mouse model of tumor rejection highlighted changes in Th1 CD4+ T cells distant to the tumor, and showed the ability of adoptive transfer of these CD4+ T cells to confer antitumor immunity (14). Adoptive transfer of human CD4+ T cells specific for a neoantigen resulted in a clinical response in a patient with cholangiocarcinoma (28), and early results from neoantigen vaccination trials that elicited predominantly CD4+ T-cell responses support the clinical efficacy of these approaches (17, 40). Despite significant evidence pointing toward the importance of CD4+ T-cell responses to neoantigens, many epithelial cancers lack class II MHC, and the precise mechanisms through which CD4+ T cells mediate antitumor immunity remain to be fully elucidated.
