    The study analyzed 92 inflammatory biomarkers in scalp psoriasis patients using Olink high-throughput proteomics.

  • 2

    Twenty-eight differentially expressed proteins were identified in lesional scalp skin of psoriasis patients compared to healthy controls.

    Scalp psoriasis exhibited a Th1/Th17/IL-12/IL-23-dominant molecular signature with down-regulation of Th2-type cytokines.

  • 4

    Reduced levels of IL-4 and IL-5 in scalp psoriasis were negatively correlated with scalp-specific Investigator’s Global Assessment scores.
