DIFFERENTIATION OF NK CELLS. A LOOK THROUGH THE PRISM OF TRANSCRIPTION FACTORS AND INTRACELLULAR MESSENGERS
All lymphoid cells are referred to as an innate or adaptive immunity unit in terms of the mechanisms of performing immune reactions. The functional activity of natural killer (NK) cells is not associated with pre-activation processes resulting from contact with antigen, rearrangement of antigen-reco...

All lymphoid cells are referred to as an innate or adaptive immunity unit in terms of the mechanisms of performing immune reactions. The functional activity of natural killer (NK) cells is not associated with pre-activation processes resulting from contact with antigen, rearrangement of antigen-recognition receptor genes, and clonal proliferation. In this regard, NK cells are traditionally referred to as cells of innate immunity. Previously, it was believed that NK cells represent the only population of innate immunity lymphoid cells, but, more recently, there has been increasing evidence in the literature concerning existence of different populations of these cells, thus serving a basis for isolating a common cluster called Innate Lymphoid Cells (ILC). According to the ILC classification, NK cells are classified as the first group of innate lymphoid cells according to their overall functional characteristics, as well as contribution of the T-bet transcription factor to their differentiation. Complexity, multistage and partially nonlinear character of NK cell differentiation are associated with influence of the cellular microenvironment, consistent expression of transcription factors and activation of various intracellular signaling pathways in NK cells.
