FABP3 and Parkinson disease: Previous studies have also revealed that FABP3 promotes the oligomerization of αSyn in the brain of a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD [45], and that the deletion of FABP3 can block the uptake of αSyn by dopaminergic neurons and even the dispersion of αSyn in the brain [46].
