  Similar to preeclamptic women, hypertension in the chronic Reduced Uterine Perfusion Pressure Rat Model Of Preeclampsia (RUPP) is associated with increased CD4+ T cells, cytokines, sFlt-1 and agonistic autoantibodies to the AngII receptor (AT1-AA). We examined the effect inhibition of T cell co-stimulation in RUPP rats treated with (A) (abatacept, 250 mg/kg, infused i.v. at gestation day 13), on hypertension and sFlt-1, TNF-α and AT1-AA. RUPP surgical procedure was performed on day 14. On day 19 MAP increased from 94+2 mmHg in Normal Pregnant (NP) to 123 ± 3 mmHg in RUPP control rats. This response was attenuated by Abatacept, MAP was 104 ± 2 mmHg in RUPP ± A, and 96 ± 2 mmHg NP ± A. Percent circulating CD4+ T cells were 66 ± 3% in RUPPs compared to 55 ± 3% NP rats (p<0.04) but were normalized in RUPP ± A rats (54 ± 3%). The twofold.. Read More»
