在这项工作中,我们将胰高血糖素的释放置于光的控制之下。这种方法的目的是允许微创,双激素控制血糖。胰高血糖素的治疗应用面临两个主要挑战:1)所需的胰高血糖素释放量和时间是高度可变的;2)胰高血糖素在溶液中迅速纤颤,形成无活性的聚集体。我们已经开发了一种光激活胰高血糖素三聚体,其中我们通过光裂解连接体将三个胰高血糖素分子连接起来。我们证明了这种材料可以在光的刺激下以可预测的方式释放胰高血糖素。此外,我们证明了在没有光的情况下,三聚体不形成原纤维,因此在照射下释放正常的无原纤维胰高血糖素。这些特性使这种材料成为双激素光激活人工胰腺系统的理想材料。
In this work we have brought the release of glucagon under the control of light. The aim of this approach is to allow minimally invasive, two-hormone control of blood glucose. Glucagon has two major challenges associated with its therapeutic application: 1) The required amount and timing of glucagon release is highly variable, and 2) glucagon rapidly fibrillates in solution, forming aggregates that are inactive. We have developed a light activated glucagon trimer, in which we have joined three glucagon molecules via light cleaved linkers. We demonstrated that this material can be stimulated by light to release glucagon in a predictable manner. In addition, we demonstrated that in the absence of light, the trimer does not form fibrils, and thus releases normal unfibrillated glucagon upon irradiation. These qualities make this material ideal for incorporation into a two hormone light activated artificial pancreas system.
