We then measured the expression of genes involved in the synthesis (Napepld) and the degradation (Naaa and Faah) of endocannabinoids and N-acetylamines, important biomolecules involved in several biological processes, including the control of food intake and inflammation.29 The expression of Faah was induced by the HF diet, this overexpression being prevented by the probiotic mix, whereas the other tested genes were not significantly affected (Figure 5b). Here, FAAH is linked to hydrops fetalis.
