Aspartate aminotransferase is required for Salmonella expansion in the inflamed gut via TCA anaplerosis

Nicolas G. Shealy, Madi Baltagulov, H. F. Avalos…·Mariana Xavier Byndloss

This study shows that aspartate aminotransferase (AspC) is essential for Salmonella Typhimurium growth in the inflamed gut by supporting TCA cycle anaplerosis and aspartate metabolism.

Short-term alterations in dietary amino acids override host genetic susceptibility and reveal mechanisms of Salmonella Typhimurium small intestine colonization

Nicolas G. Shealy, Madi Baltagulov, Camila de Brito…·Mariana Xavier Byndloss

The paper shows that a diet rich in L-amino acids overrides genetic resistance in mice, promoting Salmonella Typhimurium ileal colonization through microbiota-dependent mechanisms.
