ABSTRACT
Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease characterized by neuro-ophthalmic intercross and humoral immunity.Neuromyelitis optica related optic neuritis (NMO-ON) is often the initial symptom of NMOSD patients, with a high blinding rate, which brought a heavy blow to the quality of life, study, work and other aspects of patients.The discovery of aquaporin-4 immunoglobulin G (AQP4-IgG) has brought significant progress in the pathogenesis, diagnosis and treatment of NMOSD.However, AQP4-IgG is not a universal biomarker of NMOSD.The role of CD4 + T helper (Th) cell related cytokines in the pathogenesis of NMOSD has been increasingly emphasized.This paper reviewed the research results of CD4 + Th cell-related cytokines closely related to the occurrence of NMOSD in recent years, including Th17 cell-related cytokines such as interleukin-6 (IL-6), IL-17, IL-21, Th2 cell-related cytokines such as IL-4, IL-5, IL-13, IL-31, IL-33, and regulatory T cell-related cytokines, etc.to provide new insights for the pathogenesis, diagnosis and treatment strategies of NMOSD or NMO-ON.
ABSTRACT
Neovascular eye diseases,with highly complicated and refractory,are one group of the most difficult problems for domestic and overseas clinical oculists in recent years.Angiogenesis is a complex process participating with multiple factors and various ways,and its exact pathogenesis is unclear yet.Ocular neovascularization is the dynamic balance result between proangiogenic factors and antiangiogenic factors provided that intraocular microenvironment be under a physiological condition.Some pathological factors including ischemia,hypoxia and inflammation destroy the dynamic balance between cytokines leading to neovascularization.Currently studies indicated that numerous cytokines containing vascular endothelial growth factor (VEGF) and pigment epithelium derived factor (PEDF) are closely linked to ocular neovascularization,while it is more crucial to elucidate the molecular mechanism of numerous cytokines involved in ocular neovascularization,which can recognize the pathogenesis of neovascular eye disease more clearly.Research progress of pathological relevant cytokines of neovascular eye diseases,including VEGF,insulin-like growth factor 1 (IGF-1),angiogenin-2 (Ang-2),stromal cell derived factor 1 (SDF-1) and PEDF were reviewed in this paper.
