How Smoking Intensifies Periodontitis

Spatial transcriptomics links smoking to epithelial damage, inflammatory cell interactions, points to CXCL12 as potential therapeutic target.

Researchers created a high-resolution map of human gum tissue to study smoking's effects on periodontitis.
2

Smoking weakens the gum's epithelial barrier, leading to structural and functional damage.
3

Fibroblasts in smokers show increased activity in genes related to aging, cell death, and wound repair.
4

Smoking-related periodontitis has more immune cells, particularly proinflammatory macrophages.

CXCL12 is identified as a potential therapeutic target to mitigate smoking-related periodontitis.
