IL17A and psoriasis: Beyond DEG analysis, gene set enrichment analysis (GSEA) has been applied to psoriasis research, revealing enriched pathways associated with IL-17 signaling, proteasome activity [16], transcription factors, JAK/STAT signaling [15], antiviral defense mechanisms [17], ribosomal function [18], vascular smooth muscle contraction, and p53 signaling [19].
