Interactive Effect of Plasma Lipidome on Neuropsychiatric Disorders: A Bidirectional Mendelian Randomization Study.
Lipid metabolism disruptions are implicated in nervous and mental disorders; plasma lipidomics show promise as diagnostic and therapeutic targets. However, clarification of causal relationships between plasma lipids and neuropsychiatric disorders (NPDs) remains unclear. We employed bidirectional Mendelian randomization (MR) to examine causal links between 179 plasma lipids and 17 NPDs. Significant associations in the forward MR were further investigated using linkage disequilibrium score regression (LDSC), Bayesian colocalization (COLOC) analysis, and mediation analysis. Forward MR revealed sterol ester (27:1/16:1) and diacylglycerol (16:0_18:2) elevations may increase anorexia nervosa (AN) risk, while sphingomyelin (d36:2) elevation potentially lowers it. LDSC analysis showed no substantial genetic link between the three lipids and AN, while low posterior probability of hypothesis 4 from COLOC test disputed the presence of shared variants. Besides, AN risk elevated by sterol ester's (27:1/16:1) was suggested to mediate through C-X-C chemokine 10 downregulation. In the reverse MR, we uncovered varied causal ties: ADHD increased sterol ester (27:1/20:3), phosphatidylcholines (18:0_20:3, 18:1_20:3); Alzheimer's disease lowered phosphatidylcholine (O - 18:1_20:3); Ischemic stroke tied to less phosphatidylcholine (16:0_0:0); Obsessive-compulsive disorder exhibited a dual effect, upregulating phosphatidylcholine (16:1_18:0) and downregulating sterol ester (27:1/22:6); Parkinson's disease linked to less diacylglycerol (18:1_18:3); Schizophrenia tied to more triacylglycerols (48:0,51:1); Migraine reduced sterol ester (27:1/20:2). These insights reveal causal dynamics between plasma lipids and neuropsychiatric conditions. Our findings extend the causal landscape linking the plasma lipidome to NPDs, offering insights for the discovery of novel biomarkers and therapeutic targets in these diseases.
期刊介绍:
Molecular Neurobiology is an exciting journal for neuroscientists needing to stay in close touch with progress at the forefront of molecular brain research today. It is an especially important periodical for graduate students and "postdocs," specifically designed to synthesize and critically assess research trends for all neuroscientists hoping to stay active at the cutting edge of this dramatically developing area. This journal has proven to be crucial in departmental libraries, serving as essential reading for every committed neuroscientist who is striving to keep abreast of all rapid developments in a forefront field. Most recent significant advances in experimental and clinical neuroscience have been occurring at the molecular level. Until now, there has been no journal devoted to looking closely at this fragmented literature in a critical, coherent fashion. Each submission is thoroughly analyzed by scientists and clinicians internationally renowned for their special competence in the areas treated.
