A detailed comparison of gene expression signatures between ETP ALL tumors and and normal human hematopoietic progenitor cells revealed a somewhat surprising finding: ETP - ALL expression patterns were less consistent with early T - cell precursors, as might have been expected, but more similar to the expression profile of normal hematopoietic stem cells and granulocyte macrophage precursors.

Although similar numbers of total splenic gp33 - LCMV — specific T cells were observed between genotypes (Fig. 5B), the distribution of gp33 - LCMV — specific CD8 + T cell effector and memory subsets were altered, such that there was a significantly lower percentage of short - term effector T cells and reciprocal changes in memory precursor cells among gp33 - specifc CD8 + T cells in WT relative to DKO mice (Fig. 5C), with a trend in changes in absolute cell numbers, consistent with temporal data from peripheral blood (Fig. 5A).

Six weeks postinfection, splenocytes were analyzed for gp33 - LCMV — specific total CD8 + T cells (B) or short - lived effector cells and memory precursor effector cells (C).

Consistent with prior reports on effector cells (35), we observed that, among CD8 + T cells specific for the dominant epitope of LCMV (GP33), the percentages of short - lived effector cells (KLRG1 + CD127 −) were increased, and the percentages of memory precursor cells (KLRG1 + CD127 +) were decreased in the peripheral blood of DGKζ − / −, Cbl - b − / −, and DKO mice relative to WT mice after acute infection (Fig. 5A).
