The CD8 T cell response generatedby gene-based vaccines is importantfor protective immunity againstmany infectious diseases but its complexityis incompletely understood.Here, we report that different vaccinesencoding HIV Env elicit qualitativelydistinct CD8 T cells that wereidentified by patterns of gene expressionin individual cells. Three alternativeprime-boost vector combinationsstimulated antigen-specific CD8 Tcell populations of similar magnitudeand function by intracellular cytokinestaining; however, single cell geneexpression profiling enabled the discriminationof distinct CM and EMCD8 cells elicited by the three vaccines.Two previously unrecognizedCD8 T cell subsets have been definedby their coexpression of Eomes,Cxcr3 and Ccr7; or Klrk1, Klrg1 andCcr5 in CM and EM cells respectively.
