Outside the HLA region, a set of susceptibility variants are identified, closely related to interleukin (IL)-23/IL-17 pathway, tumor necrosis factor<span> (TNF) signaling, and pattern recognition receptor systems. Microbial infections, such as </span></span></span><span><em>Streptococcus sanguinis</em></span>, <span><em>Mycobacterium tuberculosis</em></span><span><span><span><span>, and Herpes simplex virus (HSV), are linked to play the triggering of disease in immunogenetically predisposed individuals. Clinically, due to the notable relapsing-remitting course of ocular Behçet's disease, the prevention of recurrent attack would be the primary </span>treatment goal. Combination of corticosteroids and </span>immunomodulatory drugs, such as anti-TNF agents, </span>interferon<span><span>, and conventional immunosuppressants (e.g. </span>cyclosporine<span>, azathioprine), have been the mainstream regimen for the disease. Future research may focus on comparing the effectiveness of immunomodulatory drugs and identifying the most suitable subgroups for a specific drug on the basis of the knowledge of the molecular heterogeneity of the disease.</span></span></span></p></div>","PeriodicalId":21159,"journal":{"name":"Progress in Retinal and Eye Research","volume":"97 ","pages":"Article 101216"},"PeriodicalIF":17.8,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41169708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
