Abstract

Microglia activation is closely linked to ischemia, various chronic neurodegenerative diseases (e.g., Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis), and many other central nervous system diseases. Accumulating evidence suggests that depressing the microglial inflammatory response could be an effective treatment for inflammatory disorders. The integrin αvβ3 inhibitor LXW7 has a neuroprotective effect; however, its anti-inflammatory effects and underlying mechanism remain unclear. Thus, we examined whether LXW7 would inhibit inflammatory cytokines and mediators, and we evaluated the potential mechanisms of its neuroprotective effects. Nitrite analysis revealed LXW7 reduced the nitric oxide (NO) level. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) suggested that LXW7 suppressed the expression of proinflammatory genes for tumor necrosis factor-alpha (TNF-α), interleukin 1-beta (IL-1β), inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), and anti-inflammatory gene interleukin 10 (IL-10) at the messenger ribonucleic acid level. Enzyme-linked immunosorbent assay results demonstrated that LXW7 treatment reduced the expression of prostaglandin E2 (PGE2...Continue Reading
