Join Juliane Schikora, Diana Pauly, and their collaborative research team as they explore immune molecules directly from fluid inside the eye (aqueous humour), aiming to identify new biomarkers for non-exudative (dry) age-related macular degeneration (AMD)—a major cause of vision loss. ✨
📌 Why Is This Important?
AMD development involves inflammation, immune system imbalance, and cellular stress. But exactly how these processes lead to AMD remains unclear. Reliable biomarkers—specific molecules linked to the disease—can dramatically improve early detection and treatment strategies.
👁️ What Did the Researchers Do?
The team analyzed aqueous humour samples collected during cataract surgery from dry AMD patients and healthy controls. Using advanced multiplex assays, they measured 78 immune and complement proteins, looking specifically for differences linked to AMD.
🌟 Exciting Key Findings:
Patients with dry AMD showed significantly lower levels of:
Complement factor 4 (C4) (P=0.020)
Interleukin-10 (IL-10) (P=0.033)
A positive correlation between increased drusen volume (AMD severity) and inflammatory protein CCL4 📈 was identified.
Smoking 🚬 significantly raised inflammatory proteins (CCL7, IL-7), emphasizing its role as a risk factor.
The levels of certain proteins (e.g., MMP-1) increased with age, and sex differences were observed for other complement proteins (FB, C4B).
🧪 Testing Factor H (FH)—The SciFiMed Difference:
Additionally, the researchers evaluated levels of Factor H (FH), a key complement regulator. This was possible only after thoroughly validating a commercial FH assay for specificity and accuracy, rigorously tested with the support of partners from the SciFiMed Consortium. 🌠✅
🔑 Why Do These Findings Matter?
Identifying C4 and IL-10 as potential biomarkers offers new ways to understand and track AMD progression, paving the way for earlier diagnosis, personalized treatments, and improved patient outcomes.
🚀 Next Steps:
A larger, dedicated study is now ongoing to confirm and expand upon these promising biomarker results, deepening our understanding of AMD and immune factors in the eye.
🌟 Takeaway:
Exploring immune markers in eye fluid, including rigorously tested Factor H, provides valuable insights and opens new doors for effective AMD care and research.
