ABCA1 and Stroke: Our previous study showed that ABCA1-deficient (ABCA1-B/-B) mice exhibited a marginal increase (p = 0.052) in lesion volume compared with ABCA1-floxed (ABCA1fl/fl) mice measured 7 days after stroke, with the lesion in ABCA1-B/-B stroke mice likely incorporating more edema than the lesion in ABCA1fl/fl stroke mice.
