We first conducted a qPCR analysis which proved a decrease in the hydrolysing enzyme FAAH and the synthesizing enzyme DAGL (only as a trend: p = 0.091) in the mPFC of FTD mice at PND90 (Fig. 11A), accompanied by an increase in the synthesizing enzyme NAPE-PLD in the hippocampus also at PND90 (Fig. 11B). The gene discussed is GPLD1; the disease is frontotemporal dementia.
