LARIS enables accurate and efficient ligand and receptor interaction analysis in spatial transcriptomics

LARIS

Ligand And Receptor Interaction in Spatial transcriptomics data

LARIS is a Python package for analyzing ligand-receptor interactions in spatial transcriptomics data. It identifies spatially-specific cell-cell communication patterns by integrating gene expression, spatial information, and cell type annotations.

Feature

• Spatial LR interaction strength: Calculate ligand-receptor interaction scores for each individual cell
• Spatial specificity: Identify LR pairs with significant spatial variable patterns
• Inference at cell type level: Compute sender-receiver cell type interaction scores
• Spatial neighborhoods: Analyze interactions in the context of spatial cell type neighborhoods
