Interleukin 21, Interleukin 23, and Transforming Growth Factor β1 in HLA-A29-Associated Birdshot Retinochoroidopathy – Corrected Proof

Purpose: To determine the peripheral levels of 20 immune mediators in serum samples from patients with birdshot retinochoroidopathy (BSRC).Design: Single-center prospective case-control study.Methods: The serum of 17 BSRC patients during different phases of disease activity and therapy were analyzed with a quantitative multiplex sandwich enzyme-linked immunosorbent assay–based microarray to determine the levels of 20 immune mediators (T cell and proinflammatory). The serum of 12 healthy volunteers was used as controls.Results: Serum levels of interleukin (IL)-21 (P = .0005), IL-23 (P = .0005), and transforming growth factor (TGF)-β1 (P = .0011) were elevated in BSRC patients with active disease naïve to systemic therapy compared (Read more...)
