The human parasite Leishmania amazonensis downregulates iNOS expression via NF-κB p50/p50 homodimer: role of the PI3K/Akt pathway

Abstract excerpt

Leishmania amazonensis activates the NF-κB transcriptional repressor homodimer (p50/p50) and promotes nitric oxide synthase (iNOS) downregulation. We investigated the role of PI3K/Akt in p50/p50 NF-κB activation and the effect on iNOS expression in L. amazonensis infection. The increased occupancy of p50/p50 on the iNOS promoter of infected macrophages was observed and we demonstrated that both p50/p50 NF-κB...
