Fig. 1 Soluble brain and CSF Aβ levels are not significantly reduced by bexarotene in wild-type CD1 mice and beagle dogs.(A) Soluble Aβx-37, Aβx-38, Aβx-40, and Aβx-42 levels (enzyme-linked immunosorbent assay) in whole-brain homogenate of wild-type CD1 mice treated with one dose of oral bexarotene (100 mg/kg; 20% Captisol; N = 6 mice) for 7, 24, 49, and 72 hours, and vehicle (N = 6 mice).
