KEGG pathway enrichment analysis of genes uniquely increased in ASD monocytes after LPS revealed significant enrichment in the pathogenic E. Coli infection pathway (Fig. 2B and Table S6), including several key immune regulator genes such as FAS cell surface death receptor (FAS), nuclear factor kappa B (NFKB1), and TGF beta Kinase 3 (TAB3). This evidence concerns the gene FAS and escherichia coli infection.
