# Shared Genetics in Celiac Disease and Inflammatory Bowel Disease Specify a Greater Role for Intestinal Epithelial Cells

## TL;DR

This paper explores how shared genetic factors in celiac disease and inflammatory bowel disease affect intestinal epithelial cells, highlighting their role in immune responses and disease.

## Contribution

The paper identifies shared genetic loci and their potential impact on epithelial cells in celiac disease and IBD, offering new insights into disease mechanisms.

## Key findings

- Genes in shared loci between celiac disease and IBD are expressed in intestinal epithelial cells.
- These genes may influence immune responses and disease progression through epithelial cell activity.
- Understanding these genetic effects could lead to new drug targets and personalized therapies.

## Abstract

The contribution of genetics to the development of gut-related autoimmune diseases such as celiac disease (CeD) and inflammatory bowel diseases (IBDs) is well-established, especially in immune cells, but pinpointing the significance of genetic variants to other cell types is more elusive. Increasing evidence indicates that intestinal epithelial cells are active players in modulating the immune response, suggesting that genetic variants affecting these cells could change cell behavior during disease. Moreover, fine-mapping genetic variants and causal genes to relevant cell types can help to identify drug targets and develop personalized targeted therapies. In this context, we reviewed the functions of genes in disease-associated loci shared by CeD and IBD that are expressed in epithelial cells and explored their potential impacts.
