What this research studies
This work looks at how diabetes alters dendritic cells, a key immune cell, in gum tissue so that gum disease (periodontitis) gets worse. The team will use single-cell RNA sequencing to read gene activity in individual immune cells and spatial transcriptomics to map where those cells sit in the tissue. Advanced bioinformatics will be used to find genes and pathways that are turned on or off in diabetes, and key findings will be validated in tissue samples. The project builds on new preliminary data showing diabetes-related changes in dendritic cell gene expression in vivo.
Who could benefit from this research
Good fit: Adults with diabetes who have chronic periodontitis or frequent gum infections would be the most relevant group for these findings.
Not a fit: People without diabetes or those whose gum problems are primarily mechanical or non-inflammatory may not directly benefit from this research.
Why it matters
Potential benefit: If successful, this could reveal immune pathways that explain worse gum disease in people with diabetes and point to new targets for prevention or treatment.
How similar studies have performed: Single-cell RNA-seq has mapped immune cell changes in periodontal disease before, but combining scRNA-seq with spatial transcriptomics to pinpoint diabetes-driven changes in dendritic cells is relatively new.
