The TH1-TH2 paradigm, in which CD4+ T cells polarize into type 1 or type 2 helper cells, has been extended to other cells types. However, evidence now suggests that NK cells differentiate sequentially from immature type 2 to mature type 1 cells, a pathway that could apply to other lymphocytes.

Figure 1: According to the TH1-TH2 paradigm (a), NK cell precursors (pre-NK) differentiate into NK cells producing either type 1 (NK1) or type 2 (NK2) cytokines, paralleling differentiation of TH precursors (pre-TH) into TH1 and TH2.
