The reduced NAFLD symptoms in Tcrd−/− mice were also displayed in another mouse NAFLD model induced by high-fat/high-carbohydrate diet (HFHCD) (Fig. 7e), and transfer of HFHCD-fed mice with WT hepatic γδT cells, but not with Il17a−/− hepatic γδT cells, accelerated NAFLD in Tcrd−/− mice (Fig. 7e). This evidence concerns the gene IL17A and metabolic dysfunction-associated steatotic liver disease.
