Abstract:
Tissue-specific expression quantitative trait loci (eQTLs) are always linked to specific diseases. In this study, we focused on eQTLs common to multiple tissues and explored their functional mechanisms in disease for the first time. We found 11 common eQTL genes among multiple tissues. Five genes were validated through a genome-wide association study, 3 genes were validated using the Online Mendelian Inheritance in Man database, and the others were validated through text mining. Most of these disorders were related to the systemic immune system. In functional analyses using Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes, these common eQTL genes were enriched in biological processes and pathways mostly related to the immunity. Therefore, we believe that these common eQTL genes are related to immune system.

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
