Figure Lengend Snippet: Heatmaps for IgA and IgG response showing major immunogenic regions identified in the SARS-CoV-2 whole proteome microarray. The printed proteome constitutes ORF1a/b polyprotein encoding 16 non-structural proteins (1–10 and 12–16), structural proteins (S, N, E, and M), and the accessory proteins (ORF3a, 6, 7a, 8, and 10).

Figure Lengend Snippet: Panoramic Evaluation of HLA-A*02:01 Reactivity for Peptides Derived from Arbovirus. Peptide microarray was performed with an HLA-A*02:01 dimeric protein in three concentrations (1µg/mL, 10µg/mL and 30µg/mL). Overall fluorescence of peptide-HLA-A*02:01 reactivity (top panels), absolute number of HLA-*02:01-reactive peptides (middle panels) and mean of fluorescence intensity of HLA-*02:01-reactive peptides (lower panels) were evaluated. Chi-square test (χ2) was used to compare the number of HLA-A*02:01-reactive. Obtained p values are indicated above each bar. Comparisons regarding the mean of fluorescence intensity of HLA*02:01-reactive peptides were performed using the Kruskal-Wallis. Statistical significances were considered for p < 0.05 and are indicated by connecting lines.
