Psoriasis represents a prevalent long-term inflammatory skin condition marked by the dysregulation of immune responses. T cells are integral to the pathogenesis of psoriasis. This study conducted a comprehensive analysis to recognize biomarkers associated with T cell infiltration in psoriasis and to elucidate their underlying molecular mechanisms.
Results
Three biomarkers (AKR1B10, C10orf99, and CKS2) demonstrated high sensitivity and specificity in receiver operating characteristic (ROC) curve, and the reliability of the developed nomogram diagnostic model was observed. In addition, gene set enrichment analysis (GSEA) revealed notable enrichment of the biomarkers in the NOD-like receptor signaling pathway and focal adhesion. Immune infiltration analysis indicated elevated levels of activated B cells and CD8 T cells in psoriasis samples, with the biomarkers showing meaningful correlations with the majority of immune cell infiltration statuses. Importantly, preliminary reverse transcription quantitative PCR (RT-qPCR) validation showed increased expression of AKR1B10, C10orf99, and CKS2 in psoriasis tissues, confirmed higher expression of AKR1B10, C10orf99, and CKS2 in psoriasis patients.
Conclusion
AKR1B10, C10orf99, and CKS2 may serve as candidate molecules for future mechanistic studies and provide potential diagnostic biomarkers for further investigation of psoriasis-related immune regulation.
