Inhibition of new vessel growth in mouse model of laser-induced choroidal neovascularization by adiponectin peptide II.

We have investigated the effect of adiponectin (APN) peptide II on new vessel growth in mouse model of choroidal neovascularization (CNV) or wet type age-related macular degeneration (AMD). Mice were injected intraperitoneally with APN peptide II, control peptide, or PBS on day 1-7 or day 5-14. APN, AdipoR1, PCNA, and VEGF localization was investigated using confocal microscopy, immunohistochemistry, and RT-PCR.

Expression of adiponectin in choroidal tissue and inhibition of laser induced choroidal neovascularization by adiponectin.

The aim of this study was to investigate the role of adiponectin (APN) in a mouse model of laser induced choroidal neovascularization (CNV). We have shown by immunohistochemistry that the expression of APN, adiponectin receptor 1, adiponectin receptor 2 and T cadherin gradually increased from day 1 to day 7 post-laser in laser treated mice compared to controls. Recombinant APN (rAPN) was injected intraperitoneally (i.
