Investigating plasma lipid profiles in association with Parkinson’s disease risk

Abstract

Parkinson’s Disease (PD) is associated with lipid metabolic disturbances, but the specific roles of lipids in its pathogenesis are unclear. This Mendelian Randomization (MR) study utilized GWAS data and IVW methods to investigate plasma lipids and PD risk. The genetic predispositions to altered levels of triacylglycerols (TAGs), diacylglycerols (DAGs), phosphatidylcholines (PCs), and phosphatidylethanolamines (PEs) are associated with an increased risk of PD, while the genetic predispositions to sphingomyelin (SM) and lysophosphatidylcholines (LPCs) are associated with a reduced risk of PD. Further research is needed to establish the biological mechanisms underlying these relationships.
