PPARG and Alzheimer disease: Targeting PPARγ for therapeutic benefit in AD has also recently been proposed.50 Interestingly we found that whilst the deficits in maximal respiration, glycolysis and glycolytic capacity observed in the R47H variants can be rescued by the PPARγ agonist, these deficits in the NHD hypomorphs cannot, suggesting that the reduced levels of PPARγ protein observed in these variants and the limited levels of mature TREM2 may have an uncoupling effect on the signaling to and from PPARγ.
