Fig. 3From: Cutaneous lesions in psoriatic arthritis are enriched in chemokine transcriptomic pathwaysInflammatory and homeostatic chemokine ligands and receptors are upregulated in PsA lesional skin. a Chemokine ligand and receptor interactions are indicated with lines. Red font indicates receptors and ligands which are transcriptionally upregulated in PsA skin lesions compared to healthy controls, and blue font indicates receptors and ligands which are transcriptionally downregulated in PsA skin lesions. Receptors and ligands which were not included in the transcriptional analysis are indicated by cursive writing. Expression heatmap of b chemokines and c chemokine receptors. Genes are given on the y-axis and samples on the x-axis. Expression values are given as per gene Z-scores, with high = red and low = blueBack to article page
