TDP‐43 overexpressing mice, a genetic model of frontotemporal dementia, exhibit dramatic changes in their small intestinal endocannabinoidome members, in terms of both altered concentrations of lipid mediators and expression of some of their receptors (Cnr1, Gpr119, Gpr55, Pparg) and metabolic enzymes (Napepld, Faah). The gene discussed is PPARG; the disease is frontotemporal dementia.
