Notch3 deletion regulates HIV-1 gene expression and systemic inflammation to ameliorate chronic kidney disease.

ABSTRACT: Anti-retroviral therapy (ART) has decreased human immunodeficiency virus (HIV)-1-associated morbidity. However, despite ART, immune cells remain latently infected, leading to chronic inflammation and HIV-1-associated comorbidities. New strategies are needed to target viral proteins and inflammation. We found activation of Notch3 in renal cells of the HIV-1 transgenic mouse model (HIV-Tg26) and in patients with HIV-associated nephropathy. We hypothesized that targeting NOTCH3 activation constitutes an effective therapy for HIV-related chronic kidney disease. We generated HIV-Tg26 mice with Notch3 knocked out (Tg-N3KO). Compared to HIV-Tg26 mice at 3 months, Tg-N3KO mice showed a marked reduction in renal injury, skin lesions and mortality rate. They also showed reduced renal infiltrating ce
