KLRK1 and metabolic dysfunction-associated steatotic liver disease: Likewise, the MFI of NKG2D on peripheral blood NK cells and CD56dim NK cells was significantly lower in NAFLD patients compared to healthy controls (943,5 (SD = 285,1) vs. 1173 (SD = 389,9), p = 0,0087 and 923,0 (SD = 291,0) vs. 1151 (SD = 378,2), p = 0,0097) (Fig 2B and 2D). Similarly, in the liver, the frequency of NKG2D+ total and CD56dim NK cells showed the same trend in NAFLD patients compared to healthy controls (80,55% (SD = 24,49) vs. 90,5% (SD = 5,7) and 77,52% (SD = 27,16) vs. 87,97% (SD = 6,127), respectively (Fig 2E and 2G).
