How the HLA-B51 and ERAP1 genes affect eye inflammation in Behcet's disease

Unraveling the role of HLA-B51/ERAP1 in Behcet's eye disease

NIH-funded research Stanford University · NIH-11415227

This project looks at how two genes, HLA-B51 and ERAP1 Hap10, change immune cells in people with Behcet's eye disease.

What this research studies

If you have Behcet's eye disease, researchers will compare immune cells from you and other patients who do or do not carry HLA-B51 and the ERAP1 Hap10 variant. They'll analyze blood and eye fluid samples using large-scale flow cytometry, single-cell RNA sequencing, and T cell cloning to find overactive immune cell types and clonal responses. The team will combine data from Stanford and international collaborators to link genetic status with immune behavior. The aim is to map which immune cells drive eye inflammation in people with these genetic risks.

Who could benefit from this research

Good fit: Ideal participants are people with Behcet's disease who have active or past eye inflammation and are willing to provide blood and, when possible, eye fluid samples and genetic information.

Not a fit: People without Behcet's disease, or whose eye problems are due to other causes, are unlikely to benefit directly from this research.

Why it matters

Potential benefit: If successful, this work could point to specific immune cells or pathways to target with new, more precise treatments for Behcet's eye disease.

How similar studies have performed: Immune profiling and single-cell methods have helped identify drivers in other autoimmune diseases, but applying them specifically to HLA-B51/ERAP1 in Behcet's eye disease is novel.
