简介：Glatiramer醋酸盐(GA)是过去常对待多重硬化的immunomodulatory肽药。它的处理效果被扩展了到象uveoretinitis，煽动性的肠疾病，接枝拒绝和肝的纤维变性那样的另外的自体免疫的条件。这里，我们报导GA在在cyclophosphamide(CY)改变糖尿病的临床的功课是有效的加强的非肥胖的糖尿病患者(CY点头)老鼠。有显著地减少的GA的治疗在老鼠和改善insulitis的糖尿病的率，它与增加的CD4+CD25+Foxp3+T房间反应与一致在对待老鼠。GA处理导致了抄写因素Foxp3的增加的表示并且在vivo并且在vitro提高了interleukin-4(IL-4)的生产。Foxp3的起来规定上的GA的效果通过IL-4部分被调停，是明显的。IL-4被发现维持Foxp3表示和CD4+CD25+规章的T房间(Tregs)的规章的功能。这研究提供GA通过Tregs的正式就职为类型1糖尿病有处理潜力，那增加的IL-4生产为提高的Treg在GA处理的功能部分负责的新证据。
