    APOE4 and sedentary lifestyle synergistically impair neurovascular function in the visual cortex of awake mice by Silvia Anderle, Orla Bonnar, Joseph Henderson, Kira Shaw, Andre M. Chagas, Letitia McMullan, Alexandra Webber, Kirsty McGowan, Sarah L. King, Catherine N. Hall

    Published 2025-01-01
    “…Here, we ask whether genetic and lifestyle risk factors for AD—the ε4 allele of the Apolipoprotein (APOE) gene, and physical activity—can together produce this reduction in cerebral blood flow which leads eventually to AD. Using in vivo two-photon microscopy and haemodynamic measures, we record neurovascular function from the visual cortex of physically active or sedentary mice expressing APOE3 and APOE4 in place of murine APOE. …”
