About Age-related Macular Degeneration Whole Blood
Age-related Macular Degeneration Whole Blood for Complement and Retinal Degeneration Research
Fresh Age-related Macular Degeneration Whole Blood is collected from IRB-consented donors with clinically confirmed age-related macular degeneration (AMD) and shipped same-day to preserve cell viability, DNA quality, and RNA integrity. AMD is a degenerative disease of the macula driven by complement dysregulation, oxidative stress, and lipid deposition. It is not an autoimmune disease, and whole blood is the most flexible material for the genetic and cellular arms of AMD research.
AMD Biology and Why Whole Blood
- AMD is degenerative and complement-driven. Common and rare variants in complement genes – most prominently the CFH Y402H risk variant, along with C3, CFB, CFI, and C2 – establish alternative complement pathway dysregulation as a central mechanism, and the ARMS2/HTRA1 locus at 10q26 contributes independently.
- Drusen, the extracellular deposits between the retinal pigment epithelium and Bruch’s membrane that define early and intermediate AMD, are enriched in complement proteins and oxidised lipids.
- Chronic oxidative stress on the metabolically demanding retinal pigment epithelium, compounded by smoking as the strongest modifiable risk factor, drives progressive cellular dysfunction and eventual photoreceptor loss.
- Late AMD diverges into two mechanistically distinct forms: dry AMD culminating in geographic atrophy, and neovascular (wet) AMD driven by VEGF-dependent choroidal neovascularisation. Complement inhibitors and anti-VEGF agents address these arms respectively.
- Circulating monocytes and macrophages participate in para-inflammation at the outer retina and are a recognised cellular contributor to disease progression, making the leukocyte compartment directly relevant.
- Whole blood supplies genomic DNA for complement and ARMS2 genotyping, stabilised RNA for transcriptomics, viable leukocytes for immunophenotyping, and the plasma fraction for complement protein measurement – all from one specimen.
