Recent studies have shown that fingolimod (FTY720) is neuroprotective in CNS injury models of cerebral ischemia and spinal cord injury. The purpose of the study was to examine the effect of fingolimod in a mouse model of intracerebral hemorrhage. ICH was produced in adult CD1 mice by injecting collagenase VII-S (0.5 μL, 0.06 U) into the basal ganglia. Fingolimod (or saline) was given 30 min after surgery and once daily for two days. Three days after intracerebral hemorrhage, brain edema, hematoma volume and the number of apoptotic cells were quantified. In another cohort of mice, brain atrophy was evaluated 2 weeks following intracerebral hemorrhage. Neurobehavioral tests were performed at 3, 7 and 14 days. Fingolimod significantly decreased edema, apoptosis and brain atrophy. More importantly, fingolimod enhanced neurobehavioral recovery. Preliminary experiments showed no difference in the number of inflammatory (CD68-positive) cells between the two groups. In conclusion, fingolimod exerts protective effects in a mouse model of intracerebral hemorrhage; the mechanisms underlying this neuroprotective effects deserves further study.
