abstract = {CD8+ T cells are considered prototypical cells of adaptive
immunity. Here, we uncovered a distinct CD8+ T cell
population expressing the activating natural killer (NK)
receptor NKp30 in the peripheral blood of healthy
individuals. We revealed that IL-15 could de novo induce
NKp30 expression in a population of CD8+ T cells and drive
their differentiation toward a broad innate transcriptional
landscape. The adaptor FcεRIγ was concomitantly induced
and was shown to be crucial to enable NKp30 cell-surface
expression and function in CD8+ T cells. FcεRIγ de novo
expression required promoter demethylation and was
accompanied by acquisition of the signaling molecule Syk and
the 'innate' transcription factor PLZF. IL-15-induced
NKp30+CD8+ T cells exhibited high NK-like antitumor activity
in vitro and were able to synergize with T cell receptor
signaling. Importantly, this population potently controlled
tumor growth in a preclinical xenograft mouse model. Our
study, while blurring the borders between innate and
adaptive immunity, reveals a unique NKp30+FcεRIγ+CD8+ T
cell population with high antitumor therapeutic potential.},
