Protecting and replacing tiny retinal blood vessels in macular degeneration
Choriocapillaris Protection and Replacement in AMD
This project works to protect and replace the tiny blood vessels under the retina to help people with age-related macular degeneration.

What this research studies
You would be told that researchers are looking at why tiny blood vessels (the choriocapillaris) die early in AMD and how that links to drusen and vision loss. They will examine how the immune system's terminal complement pathway and the membrane attack complex (MAC) damages these endothelial cells and why some cells are more vulnerable. The team will grow choroidal endothelial cells from induced pluripotent stem cells (iPSCs) and test whether the donor complement factor H (CFH) genotype affects how well these cells integrate, function, and survive after transplantation. Lab studies and donor-cell work together aim to guide treatments that protect existing vessels or replace damaged ones.
Who could benefit from this research
Good fit: People with early or intermediate age-related macular degeneration, especially those with drusen or signs of choriocapillaris loss, would be the most relevant participants.
Not a fit: People with unrelated eye conditions or very advanced, end-stage macular degeneration with large areas of permanent retinal loss may be unlikely to benefit.
Why it matters
Potential benefit: If successful, this work could lead to treatments that slow or prevent vision loss by protecting or replacing damaged choroidal blood vessels in AMD.
How similar studies have performed: Other research has linked complement activation to AMD and early cell-replacement approaches are promising, but replacing choroidal vessels in humans remains largely untested.
