The study reported ten proteins increased in AD but not in DLB or PD (pro-orexin, ENPP2, LAMP1, transthyretin, ApoE, carnosine dipeptidase 1, ubiquitin, caboxypeptidase E, malate dehydrogenase, and insulin-like growth factor–binding protein 2) as well as 13 additional proteins that were elevated in both AD and DLB compared with controls, including CH3L1. This evidence concerns the gene LAMP1 and Parkinson disease.
