Area of Science:

  • Cellular and Molecular Biology
  • Systems Biology
  • Bioinformatics

Background:

  • Understanding functional cell interactions within tissues is crucial but challenging.
  • Existing methods struggle to systematically identify coordinated cellular activities at the tissue level.

Purpose of the Study:

  • To introduce DIALOGUE, a novel computational method for uncovering multicellular programs (MCPs).
  • To demonstrate DIALOGUE's capability in analyzing both spatial and non-spatial single-cell data.

Main Methods:

  • DIALOGUE systematically identifies combinations of coordinated cellular programs across different cell types.
  • The method was applied to spatial transcriptomic datasets (mouse brain, human lung cancer) and single-cell RNA sequencing data.

Main Results:

  • DIALOGUE identified MCPs associated with animal behavior in mouse models.
  • In human lung cancer, DIALOGUE revealed MCPs related to immune activation and tissue remodeling.
  • Applied to disease data, DIALOGUE uncovered MCPs linked to Alzheimer's disease, ulcerative colitis, and cancer immunotherapy resistance, predicting patient outcomes.

Conclusions:

  • DIALOGUE effectively deciphers multicellular regulation in various biological contexts.
  • The method provides insights into tissue-level functional units and their role in health and disease.
  • DIALOGUE's findings in disease cohorts highlight its potential for identifying risk genes and predicting outcomes.
