Tissue-Specific Multi-Omics Integration Demonstrates Molecular Signatures Connecting Obesity to Immune Vulnerability

This study investigates the molecular connections between obesity and immune vulnerability by analyzing gene expression across multiple tissues, identifying 247 common differentially expressed genes (DEGs). Subcutaneous adipose tissue and blood show the highest number of DEGs, with key pathways involving RNA metabolism, immune system, cytokine production, and insulin response. The research highlights genes like RPL15 and RBM39 as central to obesity's molecular interactions and suggests a link between obesity and increased susceptibility to infections and diseases such as cancer. The findings underscore the complex interplay between obesity, immune function, and pathogen interactions, suggesting that obesity may compromise the body's defense mechanisms, though further experimental validation is necessary.
