Expression of CD107a and CD161 was graphed as a percentage of gated CD4+NKG2D+ T cells in control and cervical cancer groups subdivided, in turn, into the three groups based on ranges of CD4+NKG2D+ T cell percentages, which were characterized by the expression or lack of CD28 (Fig. 4a and b, respectively). The gene discussed is KLRK1; the disease is cervical cancer.
