Pro-inflammatory cytokines and chemokines, like interleukin (IL-1ß, IL-6) interferon-γ (INF-γ), tumor necrosis factor-α (TNF-α), and intracellular adhesion molecules (ICAM) are the raised inflammatory markers in diabetic retinopathy patients [2,3]. The gene discussed is TNF; the disease is diabetic retinopathy.
