Laboratory studyOther animals

Design
Laboratory study
Subjects
Tg2576 transgenic mice (Alzheimer's model) and wild-type mice
Dose used in the study
Sustained-release PEA pellets, implanted, continuous infusion
Duration
6 months
What was measured
Motivational behaviour by conditioned place preference; dendritic spine morphology in entorhinal cortex, dentate gyrus and prefrontal cortex; PPAR-alpha and BDNF expression

What the authors reported

PEA rescued conditioned place preference performance in Tg2576 mice, increased dendritic spines in wild-type and Tg2576 mice in the entorhinal cortex and dentate gyrus, and increased PPAR-alpha and BDNF expression in the prefrontal cortex, including in mice without baseline deficits.

Limits of this study

A mouse model study using sustained PEA infusion pellets, not oral dosing; it cannot show effect in people or in animals treated by mouth. The authors declare no conflicts of interest.
