在完整生物体的成熟免疫系统中诱导抗原特异性耐受取得的成功有限。因此,非特异性免疫抑制一直是预防不需要的免疫反应的首选治疗方法。在此表明,通过渗透泵长时间皮下输注低剂量的肽可将成熟T细胞转化为CD4 + 25 + 抑制性细胞,这些细胞在无抗原存在的情况下可长期持续存在,并在受到抗原攻击时产生特异性免疫耐受。所描述的过程类似于几十年前所使用的诱导耐受的方法,在无免疫反应的情况下诱导耐受,并有望成为前瞻性诱导抗原特异性耐受的有效手段,然而其抑制已经发生的免疫反应的能力仍有待确定。
The induction of antigen-specific tolerance in the mature immune system of the intact organism has met with limited success. Therefore, nonspecific immunosuppression has been the treatment of choice to prevent unwanted immunity. Here, it is shown that prolonged subcutaneous infusion of low doses of peptide by means of osmotic pumps transforms mature T cells into CD4+25+ suppressor cells that can persist for long periods of time in the absence of antigen and confer specific immunologic tolerance upon challenge with antigen. The described procedure resembles approaches of tolerance induction used decades ago, induces tolerance in the absence of immunity, and holds the promise to become an effective means of inducing antigen-specific tolerance prospectively, whereas its power to suppress already ongoing immune responses remains to be determined.
