Alzheimer’s disease shows greater neurogenesis impairment and higher bone morphogenetic protein (BMP) expression in female mouse models compared to males. Elevated BMP signaling is associated with impaired neurogenesis, and pharmacological inhibition of BMP restores neurogenesis. Estrogen increases BMP6 expression in neuronal cells, suggesting a mechanism for sex-based differences in Alzheimer’s disease.
