    Binge alcohol drinking significantly increases the risk of cerebrovascular dysfunction and constriction of cerebral arteries.

  • 2

    High-cholesterol diet and docosahexaenoic acid (DHA) supplementation independently protect against alcohol-induced cerebral artery constriction.

  • 3

    The protective effects of cholesterol and DHA may operate through a shared mechanism involving BK channel α-subunit (slo1) residue tyrosine 450.

  • 4

    DHA protection against alcohol-induced constriction is absent in male slo1Y450F knock-in mice but remains in female counterparts.

    The study highlights a sexually dimorphic pathway in the response of cerebral arteries to alcohol and dietary interventions.
