NK cell receptors (NKRs) are expressed on a subset of human T
cells, predominantly CD8+, within which they can modulate
TCR-mediated functions. In an attempt to identify the mechanisms
leading to NKR expression, we analyzed the capacity of IL-12 to
modulate the expression by T cells of the components of the CD94/NKG2-A
inhibitory receptor, a member of the C-type lectin-like family of NKR.
We show that IL-12 induces the expression of NKG2-A and/or CD94 by
CD8+ T cells in culture, and that this induction was
mediated neither by IFN-
nor by IL-15. We also show, using the
redirected killing assay, that IL-12-induced expression of both CD94
and NKG2-A led to the acquisition by T cells of a functional inhibitory
receptor. Expression of the CD94/NKG2-A inhibitory receptor was also
induced by IL-12 during T cell Ag stimulation so that in the presence
of this cytokine a high proportion of melanoma-reactive CTL induced
from PBL by melanoma peptide stimulation expressed this receptor. This
study emphasizes the implication of IL-12 in the modulation of immune
responses through NKR induction.
