The Hageman Laboratory

Dr. Hageman's primary research interest over the past 20 years has been directed toward assessment of pathways involved in the etiology of age-related macular degeneration (AMD), the leading cause of irreversible worldwide blindness. He and his colleagues have generated a definitive body of evidence that implicates a role for immune-mediated processes, specifically that of the complement system, in AMD pathogenesis and progression. Early pathobiologic investigations of eyes from human donors led to the identification of numerous complement proteins, complement activators, and complement regulatory proteins in drusen, the hallmark pathological biomarkers of the disease. More recent genetic studies led to the discovery that common variants in several complement genes - including Complement Factor H (CFH), Complement Factor H Related 1 and 3 (CFHR1 and CFHR3), Complement Factor B (CFB), Complement Factor I (CFI) and Complement Components 2 and 3 (C2 and C3) -- confer significant risk for, or protection from, the development of AMD late in life. A former director of the Human Genome Project called this breakthrough, "The first major translational research discovery to come from the Human Genome Project."

Dr. Hageman came to the Moran Eye Center in the Fall of 2009, bringing with him the largest known research laboratory transfer in the university's history - 8,000 human eyes donated for research over his career. His laboratory is focused on extending and refining his previous observations, identifying new genetic markers for AMD and examining diseases that co-segregate with AMD. Among other approaches, they are mining the state's extensive genealogical records in hopes of identifying new treatments and cures for AMD and related conditions.

Patient Care Significance

Age-related macular degeneration (AMD) is the most common cause of irreversible blindness in western populations. It blurs a person's central vision that is required to see fine detail, thus causing an enormous impact on one's productivity, independence, and quality of life.

Dr. Hageman's team continues its research with the expectation that previous breakthroughs will soon lead to diagnoses and treatments for AMD. Importantly, their discoveries point to the human eye as a window to understanding and predicting other diseases, including heart and liver disease and others.
