Figure 3. Chemokine signaling predicts immune cell homing in lung.

Dot plots showing expression of chemokine receptors (left) and ligands (right) in human lung cells (10x dataset); only cell types and chemokines with detected expression are shown. Colored lines connect ligand sources (target cells) with migrating immune cell types and ionocytes (Ion, red) expressing cognate receptor; thicker lines indicate previously unknown interactions.
