Abstract
- Abstract: In bacterial-induced peripheral nervous system (PNS) inflammation, Schwann cells (SCs) are activated, producing inducible nitric oxide synthase (iNOS), contributed to the pathogenesis of demyelinating disease, such as multiple sclerosis. Peroxisome proliferator-activated receptor-gamma (PPAR-γ) has been shown to play a protective role in cellular inflammatory responses. Here we showed that LPS-induced iNOS biosynthesis was in a concentration and time-dependent manner. In LPS-treated primary SCs, retreatment with PPAR-γ agonist remitted the increase of iNOS, p38 phosphorylation and TLR4, MyD88, augmented the expression of PPAR-γ and localization in nuclear. Coadministration of GW 9662 reversed the effect of PPAR-γ agonists. These results suggest that PPAR-γ agonists, 15d-PGJ2 and pioglitazone, had the anti-inflammatory effects. [Copyright &y& Elsevier]
