CellDialog

CellDialog analyzes ligand-receptor-mediated cell-cell communication by reconstructing intercellular connectivity networks from curated ligand-receptor interactions and single-cell RNA sequencing expression profiles to study processes such as tumor progression, metastasis, and therapy resistance.

Key Features:

• Ligand-Receptor Interaction (LRI) Curation: Performs LRI feature extraction, selection, and classification to assemble high-confidence ligand-receptor interactions.
• Three-Point Estimation Approach: Quantifies LRI-mediated intercellular communication strength using a three-point estimation method that integrates LRI filtering with single-cell RNA sequencing data.
• Comparative Analysis Capability: Benchmarks inferred communications against other tools to evaluate performance in decoding complex intercellular communications.
• Visualization Tools: Generates heatmaps and network views to represent intercellular communication patterns.

Scientific Applications:

• Tumor biology: Investigating tumor progression and metastasis by mapping ligand-receptor signaling among cell populations.
• Therapeutic target discovery and resistance mechanisms: Identifying potential therapeutic targets and elucidating mechanisms of therapy resistance through detailed signaling pathway analysis.

Methodology:

Constructs a comprehensive LRI database, performs LRI feature extraction, selection and classification, applies LRI filtering and a three-point estimation approach integrated with single-cell RNA sequencing data to reconstruct intercellular connectivity networks.
