Figure Lengend Snippet: ( A ) IgG (left) and IgA (right) reactivities of HC and HS3 serum pools towards healthy skin sections are shown. Scale bar: 100 µm. The white dotted line indicates the separation between epidermis (Epi) and dermis. ( B ) Same as in ( A ) towards healthy donor-derived KCs, with quantification of IgG signals normalized to Dapi. Scale bar: 50 µm. Mann–Whitney Statistical test, n = 3. ( C ) Dot plots illustrating the reactivity of HC and HS3 sera ( n = 11) against peptidoglycan (PGN), Keyhole limpet hemocyanin (KLH), MAPK14, lipopolysaccharide (LPS), double-stranded DNA (dsDNA), tubulin (TB), and lysozyme (LZ). Data were area under the curve (AUC) values determined by ELISA with serially diluted sera. Mann–Whitney statistical test. ( D ) Methodology for depleting HC and HS3 serum pools on bacteria (top). Panels below show the differential reactivity of HC and HS3 sera pools against LZ after depletion on P. uenonis or P. bivia , expressed as AUC values from ELISA with serially diluted sera, and as the mean percentage of IgG loss in bacteria-depleted pools ( n = 3) compared to non-depleted sera, analyzed by two-way ANOVA with Sidak’s multiple comparisons test. .
