Figure Legend Snippet: Intercellular communication analysis predicts IL-1β as a candidate upstream signal potentially associated with neutrophils. ( A ) Chord diagram showing predicted ligand–target interactions between sender cell populations and receiver SSPCs in the NonU microenvironment. Immune cell populations contributed prominently to the inferred SSPC-directed signaling network.

Dot size indicates the percentage of ligand-expressing cells, and color indicates average expression. ( C ) Heatmap showing log-fold changes in prioritized ligands in their corresponding sender populations when comparing NonU with Frac conditions. ( D ) Heatmap showing the predicted regulatory potential of prioritized ligands on SSPC target genes. Candidate transcription factors are indicated. ( E ) GO enrichment analysis of predicted IL-1β target genes in SSPCs. Ferroptosis-related terms are highlighted. ( F ) KEGG enrichment analysis of predicted IL-1β target genes in SSPCs. Ferroptosis and fatty acid metabolism pathways are highlighted.
