IFNG and ganglioneuroma: In GN-CS group, the uninterrupted increase in TNF-α and IFN-expression may have compromised the epithelial barrier and thus facilitated the translocation of the S. Typhimurium to liver and spleen, contrarily to the GN-PS group where the decrease in the expression of TNF-α and IFN-γ may be associated with improved preservation of intestinal epithelial integrity and resistance to translocation of the pathogen, which were observed in the administration of L. diolivorans 1Z.
