IL17A and infection: We identified 4278 DEGs corresponding to the effect of infection under the VA deficiency conditions (VAD-Inf, list II in the supplementary Excel file), which were visualized (Figure S3a), among which 984 upregulated DEGs were enriched for functions such as defense response to the bacterium, IL-17 signaling pathway, acute-phase response, keratinization, water homeostasis, and neutrophil apoptosis (Figure S3c, blue box on the right).
