Viral antigen mismatch affects antiviral T-cell response and may impair immunotherapeutic efficacy against adult T-cell leukemia/lymphoma
HTLV-1 transforms primary CD4+ T cells in vitro within a short time; however, majority of infected individuals maintain an asymptomatic condition, suggesting there is an equilibrium between the infected cells and the host immunity. In this study, we identified a variation in a major viral antigen epitope, HTLV-1 Tax301-309, in HLA-A24-positive individuals. Mismatch in A24/Tax301-309 multimers impaired detection of anti-Tax CTLs. Notably, over half of the TCRs of the anti-Tax CTLs did not recognize mismatched Tax301-309 peptides. These findings highlighted the importance of matching the viral antigen epitope type in T-cell-based immunotherapy against ATL by using viral antigen Tax.
