Summary
Neutrophil dysregulation in periodontitis (PD) involves distinct neutrophil states interacting with mast cells. This communication axis contributes to the inflammatory microenvironment in PD, offering new therapeutic targets.
Area of Science:
- Immunology
- Genomics
- Computational Biology
Background:
- Neutrophil dysregulation is a hallmark of periodontitis (PD).
- Understanding cellular heterogeneity and interactions is crucial for PD pathogenesis.
- Single-cell transcriptomics offers a powerful tool to dissect complex cellular microenvironments.
Purpose of the Study:
- To delineate neutrophil heterogeneity in periodontitis.
- To predict mast cell communication networks within the PD microenvironment.
- To identify novel therapeutic targets for periodontitis.
Main Methods:
- Analysis of a public single-cell RNA sequencing dataset (GSE171213) from gingival tissues.
- Utilized Seurat and Harmony for data processing and clustering.
- Employed CellChat, NicheNet, and SCENIC for cell-cell communication and regulatory program prediction.
- Performed in vitro experiments on HMC-1.2 mast cells treated with TGFB1.
Main Results:
- Identified ten distinct cell types in periodontitis, including two neutrophil transcriptional states.
- Predicted significant interactions between inflammatory neutrophils (Subtype 2) and mast cells via IL6 and SEMA4D signaling.
- Inferred neutrophil-derived TGFB1, OSM, and IL1B influence mast cell responses in proliferation, migration, and inflammation.
- In vitro TGFB1 treatment modulated mast cell proliferation, migration, and cytokine production in a TGFBR1-dependent manner.
Conclusions:
- Neutrophil heterogeneity and mast cell interactions represent a key communication axis in the periodontitis inflammatory microenvironment.
- Computational single-cell transcriptomics revealed testable hypotheses for periodontitis mechanisms.
- Identified potential therapeutic targets for periodontitis based on neutrophil-mast cell crosstalk.
