SNCA and Lewy body dementia: To demonstrate pS106-Rab12 labels pathological α-synuclein inclusions, we performed IF of pS106-Rab12 and phospho-α-synuclein S129 (pS129-Syn), along with MAP2 as a neuronal marker, in the hippocampus and adjacent temporal cortex of a control subject with Braak tangle stage 2 and a DLB case with Braak tangle stage 6.
