Causal associations between immune cells and psychiatric disorders: a bidirectional mendelian randomization analysis.

Naunyn Schmiedebergs Arch Pharmacol

Graduate School of PLA Medical College, Chinese PLA General Hospital and PLA Medical College, 28 Fu Xing Road, Beijing, 100083, China.

Extensive researches illuminate a potential interplay between immune traits and psychiatric disorders. However, whether there is the causal relationship between the two remains an unresolved question. We conducted a two-sample bidirectional mendelian randomization by utilizing summary data of 731 immune cell traits from genome-wide association studies (GCST90001391-GCST90002121)) and 11 psychiatric disorders including attention deficit/hyperactivity disorder (ADHD), anxiety disorder, autism spectrum disorder (ASD), bipolar disorder (BIP), anorexia nervosa (AN), major depressive disorder (MDD), obsessive-compulsive disorder (OCD), Tourette syndrome (TS), post-traumatic stress disorder (PTSD), schizophrenia (SCZ), and substance use disorders (cannabis) (SUD) from the Psychiatric Genomics Consortium (PGC).

Exploring the genetic causal inference between plasma lipidome and hemorrhagic stroke.

Objectives: Recent research indicates that the plasma lipidome composition may undergo alterations following hemorrhagic stroke. Nevertheless, the causal inference between plasma lipidome and hemorrhagic stroke remains elusive.

Materials And Methods: Exposure data were achieved from a recent Genome-wide Association Study (GWAS) study of 179 lipid species involving 7,174 individuals, while the outcome data were obtained from the FinnGen consortium (R10), including intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and non-traumatic intracranial hemorrhage (nITH).

Objective: This study aims to explore the genetic characteristics of pediatric sepsis through a combined analysis of multiple methods, including Mendelian Randomization (MR), differential gene expression analysis, and immune cell infiltration assessment. It explores their potential as biomarkers for sepsis risk and their involvement in immune-related pathways.

Methods: Differential expression analysis was performed using public datasets to identify genes with significant expression changes between pediatric sepsis patients and healthy controls.

Breast cancer (BC) is a prevalent malignancy in women, often necessitating tumor resection and breast reconstruction surgeries. However, the post-operation scars can be of concern, as hypertrophic scars (HS) can profoundly impact patients' quality of life. Our study used the bidirectional Mendelian randomization (MR) method to explore the potential relationship between BC and HS.
