Sex differences in cell death.

Abstract:

:Female patients experience substantial neuroprotection after experimental stroke compared with male patients, a finding attributed to the protective effects of gonadal hormones. This study examined the response of male- and female-derived organotypic hippocampal slices to oxidative and excitotoxic injury. Both oxygen and glucose deprivation and N-methyl-D-aspartic acid exposure led to neuronal death; however, female-derived cultures sustained less injury than male-derived cultures. Cell death after oxygen and glucose deprivation was ameliorated in male cultures, but not female cultures, by the addition of 7-nitroindazole, a neuronal nitric oxide synthase inhibitor. These studies have relevance to researchers investigating neuroprotective agents in mixed sex experiments.
