Moreover, Siglec-7 levels on CD56dim NK cells correlated positively with levels of the activation molecules Siglec-9, NKp30, and NKp46, and negatively with levels of the inhibitory molecules CD57, PD-1, and ILT2 (Supplementary Figure 3), suggesting that Siglec-7 could be a surrogate marker of the functional status of CD56dim NK cells in NAFLD patients. Here, PDCD1 is linked to metabolic dysfunction-associated steatotic liver disease.
