Proteomic profiling of MAIT cell activation. (A) Principle component analysis of the proteome of MAIT cells stimulated with IL-12/IL-18, a-CD3/a-CD28 or a combination of both. Each point represents a single donor (n=4). Overlap of (B) all detected proteins and (C) differentially abundant proteins in stimulated MAIT cells. (D) Volcano plots highlighting differentially abundant proteins in stimulated MAIT cells (p-value ≤ 0.05). (E) Heatmap of selected, significantly enriched pathways with a z-score reflecting up- or downregulation, determined by IPA (padj ≤ 0.5).
