Rewiring of intercellular ligand-receptor communication in aged tissue

I am sharing a visualization exploring how intercellular signaling architecture is remodeled with chronological age.

#CellCommunication #LigandReceptor #SingleCellTranscriptomics #SpatialTranscriptomics #Stromalniche
Rewiring of intercellular ligand-receptor communication in aged tissue I am sharing a visualization exploring how intercellular signaling architecture is remodeled with chronological age. The figure ("Log2 fold-change (old vs young) in signaling pair activity across niches; simulated data") uses a diverging lollipop layout with a dual-panel mirror, presenting ligand-side and receptor-side activity shifts in vertically aligned registers. This mirror design allows direct visual comparison of whether a given signaling pair is being driven predominantly by altered ligand availability, receptor expression, or coordinated changes in both. I want to emphasize at the outset that the underlying data are simulated. The magnitudes and directionality, however, are parameterized to reflect trends repeatedly reported in the CellChat and CellPhoneDB-based literature on aged niches, so the figure is intended as an illustrative scaffold rather than an empirical claim. Several patterns are worth highlighting for discussion. Pro-inflammatory axes such as TNF-TNFRSF1A and CCL2-CCR2 display positive log2 fold-changes, consistent with the inflammatory remodeling and myeloid recruitment characteristic of aged stromal compartments. Conversely, WNT and NOTCH ligand-receptor pairs trend negative, mirroring reported attenuation of niche-derived regenerative and self-renewal cues. TGFB1-TGFBR2 shows a positive shift concordant with fibrotic reprogramming. The mirror arrangement makes clear that certain pairs are receptor-limited in the aged condition, which has implications for how one interprets deconvolved communication probabilities. Methodologically, I would welcome perspectives on normalization strategies for cross-niche comparison, particularly how to control for compositional shifts in cell-type abundance that can confound inferred communication strength.

Unveiling cancer's hidden messengers: How extracellular vesicles aid tumor spread
Most cells in the body send out little messengers called extracellular vesicles that carry proteins, lipids, and other bioactive molecules to other cells, playing an important role in intercellular communication. But healthy cells are not the only ones that rely on extracellular vesicles. Cancer cells do, too. Small extracellular vesicles that are shed from tumor cells contribute to how cancer spreads to healthy tissue.
