Abstract
Background
The intestine of children with severe malnutrition (SM) shows structural and functional changes that are linked to increased infection and mortality. SM dysregulates the tryptophan-kynurenine pathway, which may impact
processes such as SIRT1- and mTORC1-mediated autophagy and mitochondrial homeostasis. Using a mouse and
organoid model of SM, we studied the repercussions of these dysregulations on malnutrition enteropathy and the protective capacity of maintaining autophagy activity and mitochondrial health.
