GPR37 aggregates were later also found in a variety of inclusion bodies in a study by Murakami et al. (2004), who probed the brains from patients with Parkinson’s disease (PD, n = 6), dementia with Lewy bodies (DLB, n = 3), multiple system atrophy (MSA, characterized by glial cytoplasmic inclusions, n = 6) and six control subjects. Here, GPR37 is linked to multiple system atrophy.
