In contrast, αsyn aggregate interactions (i.e., BAR-PSER129) were markedly different between MSA and PD/DLB, with several glial-enhanced proteins (CBR1, CRYAB, and GFAP) (Human Protein Atlas proteinatlas.org27)28 being more abundant in MSA αsyn aggregates (i.e., PD vs. MSA contrast). This evidence concerns the gene CRYAB and Parkinson disease.
