A) Circulating NP (n=13), circulating RUPP (n=9), circulating RUPP + ETAN (n=9). B) Placental NP (n=5), placental RUPP (n=6), placental RUPP + ETAN (n=3). C) Renal NP (n=12), renal RUPP (n=11), renal RUPP + ETAN (n=6). Activated NK cells were quantified using flowcytometry. Statistical differences were achieved using one-way ANOVA with Bonferroni post hoc analysis, *p < 0.05 vs NP and +p < 0.05 vs. RUPP.
