The function of L1 cell adhesion molecule (L1), critical for proper brain development, is dependent on detergent\u2010resistant membrane microdomains (DRM). Ethanol at low concentrations disrupts L1 function measured by inhibition of downstream signaling and alterations in L1\u2010DRM distribution in cerebellum in vivo and in cerebellar granule neurons (CGN) in vitro. We have previously shown that choline pretreatment of CGN partially prevents ethanol toxicity through improving L1 function in vitro. Here we show that choline supplementation reduces the impact of ethanol on L1 in cerebellum in vivo.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Pregnant rat dams were placed on choline free diet on gestational Day 5 (G5).

On P5, pups were intubated twice 2 hr apart with ethanol or Intralipid\u00ae for a total dose of 6 g\/kg\/d and sacrificed 1 hr after the last intubation.
