Antioxidant and Anti-Inflammatory Activity of Combined Phycocyanin and Palmitoylethanolamide in Human Lung and Prostate Epithelial Cells

Loredana Bergandi, Giulia Apprato, Francesca Silvagno. Antioxidants (Basel). 2022 Jan 21;11(2):201.

Laboratory studyHumansWith phycocyanin

This study tested palmitoylethanolamide together with phycocyanin. Its results cannot be assigned to palmitoylethanolamide alone. More combination studies.

Design
Laboratory study
Subjects
Human bronchial epithelial cells (Beas-2B) and human prostate epithelial cells (HPrEpiC), exposed to an infectious stimulus
Dose used in the study
Phycocyanin and palmitoylethanolamide, alone and combined, applied to cultured cells
Duration
Not stated in the abstract
What was measured
Cytotoxicity, reactive oxygen species production, and inflammatory cytokine transcription in stimulated cells; cyclooxygenase-2 activity, glutathione synthesis and mitochondrial respiratory burst

What the authors reported

The phycocyanin and palmitoylethanolamide combination protected against cytotoxicity and reduced both reactive oxygen species production and inflammatory cytokine transcription. It reduced oxidative stress and inflammation by inhibiting cyclooxygenase-2, increasing glutathione synthesis, and decreasing infection-driven mitochondrial respiratory burst.

Limits of this study

A cell-line study; it cannot show effect in people. The authors declare no conflict of interest.
