Age-related Macular Degeneration PBMC

Age-related Macular Degeneration PBMC for Retinal Degeneration and Complement Research

Age-related Macular Degeneration Human PBMC products are sourced from IRB-consented donors clinically diagnosed with age-related macular degeneration (AMD), processed within 24 hours of collection and cryopreserved in CryoStor CS10 freezing media. AMD is a degenerative disease of the central retina in which complement dysregulation and mononuclear phagocyte involvement are central mechanisms, rather than autoimmunity.

Why PBMC for Age-related Macular Degeneration Research

  • AMD has one of the most firmly established complement genetics of any common disease. Risk variants in CFH, including the Y402H polymorphism, and in C3, CFB, C2 and CFI, together with the ARMS2/HTRA1 locus, define genetic risk, and complement components are found within drusen. PBMC provide a ready source of donor genomic DNA for genotyping alongside functional cells from the same individual.
  • That complement biology is now therapeutically actionable: complement inhibition is approved for geographic atrophy. PBMC from AMD donors allow complement activation, regulation and inhibitor pharmacology to be studied in patient-derived cells that carry the relevant risk genotypes.
  • Mononuclear phagocytes accumulate in the subretinal space in AMD, and circulating monocytes are the source population. PBMC contain that monocyte compartment, enabling monocyte-derived macrophage differentiation, polarisation and phagocytosis assays relevant to drusen and debris clearance.
  • Altered chemokine receptor expression on circulating monocytes, involving CCR2 and CX3CR1 among others, has been reported in AMD, making PBMC-based immunophenotyping and migration assays directly relevant to the recruitment step.
  • Monocytes and macrophages both produce and respond to complement components locally, so PBMC-derived cells let researchers examine the intersection of the two dominant mechanisms in the same experimental system.
  • Cryopreserved PBMC support single-cell RNA sequencing, high-parameter cytometry and transcriptomic profiling of the systemic immune compartment in a disease whose primary lesion is not otherwise accessible in living donors.

Donor Stratification Available

  • Disease stage: early, intermediate, or late AMD, with AREDS severity category where documented
  • Late-stage subtype: geographic atrophy (dry) versus neovascular or exudative (wet) AMD, and unilateral versus bilateral involvement
  • Treatment status: treatment-naive, intravitreal anti-VEGF therapy with agent and injection history, or complement inhibitor therapy for geographic atrophy
  • Genotype where documented, including CFH and ARMS2 risk alleles
  • Risk factor context: smoking status, AREDS2 supplement use, cardiovascular comorbidity, and visual acuity where documented
  • Matched age-matched healthy controls available, and other retinal degeneration donors such as Stargardt disease for comparison
