LAST II: Differential temporal responses of macular pigment optical density in patients with atrophic age-related macular degeneration to dietary supplementation with xanthophylls
, such as lutein, are more potent immunostimulators than [beta]-carotene, and their primary action site in humoral immune response is similar to that of T-helper cells (KRAMER & BURRI, 1997).

Our findings are in agreement with earlier studies that carotenoids, especially xanthophylls
inhibit P-gp activity and enhance the antiproliferative effects of anti-cancer drugs in overexpressing P-gp lymphoma and breast cell lines (Gyemant et al.
