Figure Legend Snippet: Autoantibody Detection Unveils an Autoreactive Repertoire Enriched in MIS-C Patients (A) Upset plots delineating the number of shared autoantibodies between MIS-C patients, which were at least two-fold enriched when compared with controls for IgG autoantigens in HuProt protein microarray analysis. Upset plots were anchored on autoantibodies that were present in at least one IVIG-treatment-naïve sample (MIS-C 3 and MIS-C 9). Only intersections of 6 or more patients are visualized. (B) Corresponding upset plots for IgA autoantigens. (C) Heatmap of all IgG autoantigens with at least 4-fold enrichment in MIS-C compared to controls, in addition to the selection criteria above. Color intensity corresponds to the log 2 FC expression value relative to the mean of healthy pediatric controls (N=4). Flagged autoantigens were enriched in 5 patients and at least one treatment naive IVIG (MIS-C 3 or MIS-C 9) sample. (D) Corresponding heatmap for IgA autoantigens. (E) Top: validation of protein microarray hits identified by phage immunoprecipitation sequencing (PhIP-seq) for IgG autoantigens. The purple circle and corresponding number indicate the number of autoantigens enriched in the HuProt protein microarray that were also validated by PhIP-seq. Autoantigen peptides were collapsed at the gene level for overlap analyses. Bottom: corresponding overlap for IgA autoantigens. (F) Standard ELISA for CD244 auto-reactivity in MIS-C and healthy control plasma. (G) GSEA (gene set enrichment analysis) analysis of IgG autoantigens in treatment naïve MIS-C patients (N = 2; MIS-C 3 and MIS-C 9) versus age matched healthy controls (N = 4) ranked by t statistic. Dot color intensity corresponds to adjusted p value (FDR) and dot size represents the number of autoantigens found to be enriched in the associated gene set. (H) Corresponding enrichment scores for significantly (FDR<0.05) enriched biological pathways for IgG (regulation of immune response) and IgA (lymphocyte mediated immunity). Benjamini-Hochberg method was used to correct for multiple comparisons. See also
