Immune cell traits and causal relationships with cholecystitis: a mendelian randomization analysis

Area of Science:

• Immunology
• Genetics
• Gastroenterology

Background:

• Cholecystitis (gallbladder inflammation) involves immune cells, but their specific causal roles are unclear.
• Understanding immune cell contributions is crucial for developing effective cholecystitis treatments.

Purpose of the Study:

• To investigate the causal relationships between 731 immune cell phenotypes and cholecystitis using Mendelian randomization (MR).
• To identify specific immune cell markers that influence cholecystitis risk for precision medicine.

Main Methods:

• Employed a two-sample Mendelian randomization (MR) analysis using genome-wide association studies (GWAS) data.
• Utilized single nucleotide polymorphisms (SNPs) as genetic instrumental variables for immune cell phenotypes and cholecystitis.
• Conducted sensitivity analyses and reverse MR to ensure result robustness and rule out reverse causality.

Main Results:

• Identified 21 out of 731 immune cell phenotypes with a significant causal relationship to cholecystitis (P < 0.05).
• Eight immune phenotypes showed a protective effect (OR < 1), while 13 increased cholecystitis risk (OR > 1).
• False discovery rate (FDR) analysis did not reveal significant causal links at FDR < 0.2.

Conclusions:

• Immune cell phenotypes play a significant causal role in the development and progression of cholecystitis.
• These findings support the development of novel biomarkers and targeted therapies for personalized cholecystitis treatment.
• The study provides a foundation for improving patient outcomes and mitigating the disease's impact.
