MAPT and synucleinopathy: The main results of the present study were that (1) a variety of neurons expressed the FABP3 protein in human brain tissues, (2) FABP3 was colocalized with αSyn aggregates in the brain tissues of patients with synucleinopathies but not with amyloid β or p-tau aggregates in the brain tissues of patients with AD, and (3) FABP3 was not present in p-αSyn deposits in biopsied skin tissues of patients with PD.
