Abstract
Neuroprotective effect of lipoxin A4 methyl ester (LXA4 ME) was tested in a rat model of permanent middle cerebral artery occlusion. LXA4 ME was administrated through intracerebroventricular injection immediately after middle cerebral artery was occluded. Administration of LXA4 ME ameliorated neurological deficit, reduced infarct volume, attenuated histological damage, and decreased number of apoptotic neuron induced by ischemic insult. These neuroprotective effects of LXA4 ME were associated with inhibition of neutrophil infiltration, lipid peroxidation, and astrocyte activation. In addition, LXA4 ME also attenuated proinflammatory cytokines (TNF-α and IL-1β) production. These data suggest that LXA4 ME protects neuron against permanent cerebral ischemia by inhibiting inflammatory responses.
