Cells can also develop mutations in the thrombopoietin receptor, MPL, or in the chaperone protein, Calreticulin or CalR.

细胞内的促血小板生成素受体（MPL）或伴侣蛋白/钙网蛋白（CalR）也可以发生突变。

Engineers at Johns Hopkins’ Applied Physics Laboratory have been developing a device called a Modular Prosthetic Limb, or MPL, which is an incredibly functional robotic arm.

约翰霍普金斯大学应用物理实验室的工程师开发种称为块化假肢或 MPL 的，是种功能强大的机械臂。

In 2014, this surgery allowed a patient, who lost both arms as a teenager, to wear and control two MPLs and perform basic tasks by just thinking about them.

2014 年，项手术让位十几岁时失去双臂的患者佩戴并控制了两个 MPL，只需用意念即可完成基本任务。

So, even though the patient didn’t need a prosthetic arm, researchers working on the MPL were able to use the information from his sensors to program their device.

因此， 即使患者不需要假肢，研究 MPL 的研究人员也能够使用来自他的传感器的信息来对他们的进行编程。
