TLDEMRHFY: HLA-A*01:01 and NEVVVKEEY:HLA-B*18:01, were able to directly label ex vivo and thereby identify and enumerate malaria antigen-specific CD8+ T cells in two AdCA-immunized HLA-A*01:01+ volunteers and one AdCA-immunized HLA-B*18:01+ volunteer, respectively. The gene discussed is HLA-A; the disease is malaria.
