Recent Advances in Studies on the Therapeutic Potential of Dietary Carotenoids in Neurodegenerative Diseases

Abstract EN

Carotenoids, symmetrical tetraterpenes with a linear C40 hydrocarbon backbone, are natural pigment molecules produced by plants, algae, and fungi.

Carotenoids have important functions in the organisms (including animals) that obtain them from food.

Due to their characteristic structure, carotenoids have bioactive properties, such as antioxidant, anti-inflammatory, and autophagy-modulatory activities.

Given the protective function of carotenoids, their levels in the human body have been significantly associated with the treatment and prevention of various diseases, including neurodegenerative diseases.

In this paper, we review the latest studies on the effects of carotenoids on neurodegenerative diseases in humans.

Furthermore, animal and cellular model studies on the beneficial effects of carotenoids on neurodegeneration are also reviewed.

Finally, we discuss the possible mechanisms and limitations of carotenoids in the treatment and prevention of neurological diseases.
