IL17A and infection: The results of GSEA analysis showed that the expression of gene sets in neutrophil extracellular trap formation (P < 0.0001), IL-17 signaling pathway (P < 0.0001), hematopoietic cell lineage (P < 0.0001) and natural killer cell-mediated cytotoxicity (P < 0.0001) was higher in normal + infection group and lower in undernutrition 75% + infection group (Fig. 7B).
