Type 1 diabetes (T1D) is a chronic autoimmune disorder characterized by destruction of insulin-producing pancreatic beta cells. Many broad-based immunosuppressive and antigen-specific immunoregulatory therapies have been and are currently being evaluated for their utility in the prevention and treatment of T1D. Looking forward, this review discusses the potential therapeutic use of antigen-specific tolerance strategies, including tolerance induced by "tolerogenic" antigen-presenting cells pulsed with diabetogenic antigens and transfer of induced or expanded regulatory T cells, which have demonstrated efficacy in nonobese diabetic (NOD) mice. Depending on the time of therapeutic intervention in the T1D disease process, antigen-specific immunoregulatory strategies may be employed as monotherapies, or in combination with short-term tolerance-promoting immunoregulatory drugs and/or drugs promoting differentiation of insulin-producing beta cells from endogenous progenitors.
1 型糖尿病(T1D)是一种慢性自身免疫性疾病,其特征是破坏产生胰岛素的胰腺β细胞。目前已经有许多基于广泛的免疫抑制和抗原特异性免疫调节治疗方法正在被评估其在预防和治疗 T1D 中的效用。展望未来,本文讨论了抗原特异性耐受策略的潜在治疗用途,包括用致糖尿病抗原脉冲处理的“耐受性”抗原呈递细胞诱导的耐受和诱导或扩增的调节性 T 细胞的转移,这些方法在非肥胖糖尿病(NOD)小鼠中已证明有效。根据 T1D 病程中治疗干预的时间,抗原特异性免疫调节策略可以作为单一疗法,或与短期促进耐受的免疫调节药物和/或促进内源性祖细胞产生胰岛素的β细胞分化的药物联合使用。
