Laboratory studyOther animalsWith luteolin (co-ultramicronised PEA/luteolin, PEALut)

This study tested palmitoylethanolamide together with luteolin (co-ultramicronised PEA/luteolin, PEALut). Its results cannot be assigned to palmitoylethanolamide alone. More combination studies.

Design
Laboratory study
Subjects
Rats given a single hippocampal infusion of amyloid-beta (1-42), 5 micrograms, to model prodromal Alzheimer's disease
Dose used in the study
Co-ultramicronised PEALut, 5 mg/kg, administered for 14 days
Duration
14 days
What was measured
Glial activation (astrogliosis, microgliosis), pro-inflammatory cytokine and enzyme gene expression, and BDNF/GDNF mRNA levels after amyloid-beta infusion

What the authors reported

This laboratory study found:

  • Amyloid-beta infusion raised glial activation and pro-inflammatory mediators.
  • Early PEALut treatment prevented the amyloid-beta-induced astrogliosis and microgliosis.
  • PEALut treatment prevented the rise in pro-inflammatory cytokine and enzyme gene expression, and prevented the reduction in BDNF and GDNF mRNA.
  • PEALut also promoted neuronal survival.

Limits of this study

A rat model of induced amyloid-beta pathology; it cannot show effect in people. Funded by a Sapienza University of Rome grant; no other conflicts stated.
