Additionally, extracts of both microalgae contain lutein, which reduces lipid peroxidation (assessed as MDA), as well as levels of eicosanoids (PGE2, LTB4 and LTC4) and C-reactive protein and cytokines (TNF-α, IL1-β and MCP-1), and also increases the activity of antioxidant enzymes in the blood serum of rats with cataracts [117]. Here, CRP is linked to cataract.
