Laboratory studyHumansWith cannabidiol (tested alone; PEA was a measured lipid)

This study tested palmitoylethanolamide together with cannabidiol (tested alone; PEA was a measured lipid). Its results cannot be assigned to palmitoylethanolamide alone. More combination studies.

Design
Laboratory study
Subjects
Keratinocytes isolated from the skin of psoriasis patients and healthy volunteers, with or without UVA/UVB irradiation
Dose used in the study
Cannabidiol in culture; concentration not stated in the abstract
Duration
Not stated in the abstract
What was measured
Reactive oxygen species, thioredoxin system, vitamins A and E, lipid peroxidation products, anandamide and palmitoylethanolamide levels, CB1 and CB2 receptor expression, and transporter activity.

What the authors reported

This laboratory study found:

  • CBD reduced oxidative imbalance in irradiated keratinocytes from healthy people but tended to raise oxidative and inflammatory state in cells from psoriasis patients.
  • Anandamide fell in healthy cells and rose in patient cells with CBD, while palmitoylethanolamide fell in both groups.
  • CBD raised CB1 expression mainly in patient cells and CB2 in both, and normalised MDR and BCRP transporter activity.

Limits of this study

A cell culture study of cannabidiol; PEA was measured, not given. Results in cells cannot show effect in people. The authors declare no conflicts of interest.
