Abstract
Age-related macular degeneration (AMD) is a multifactorial disease of the retina featured by dysfunction of retinal pigmented epithelial (RPE) and loss of photoreceptor cells under oxidative stress and inflammatory conditions. Vitamin D and antioxidants have beneficial effects against retinal degenerative diseases, such as AMD. We investigated the impact of associating vitamin D (ND) with a nutritional antioxidant complex (Nutrof Total®; N) on oxidative stress and inflammation-like induced conditions by H2O2 and LPS, respectively, in human retinal epithelial (ARPE-19) and human retinal endothelial (HREC) cells. Application of either N or ND treatments to H2O2-induced media in ARPE-19 cells counteracted late apoptosis, attenuated oxidative DNA damage, and increased cell proliferation. Significant reduction in the expression levels of MCP1, IL-8, and IL6 cytokines was observed following application of either N or ND treatments under LPS-induced conditions in ARPE-19 cells and in MCP-1 and IL12p70 cytokine levels in HREC cells. ND and not N revealed significant downregulation of IFNγ in ARPE-19 cells, and of IL-6 and IL-18 in HREC cells. In conclusion, adding vitamin D to Nutrof Total® protects in a synergistic way against oxidative and inflammatory stress-induced conditions in retinal epithelial and endothelial cells.

Abstract
The events that lead to choroidal neovascularization in eyes with age-related macular degeneration are poorly understood. One possibility that has been explored in a number of studies is that macrophages can promote neovascular changes. In this paper, we summarize the evidence for inflammation in general and macrophages in particular in pathologic neovascularization, and discuss how the diverse functions of these cells may promote or inhibit macular disease. We also discuss some of the conflicting findings regarding the role of macrophages in experimental choroidal neovascularization in mouse models, and suggest areas for future research.
