  Pioneering type 1 diabetes therapy safe

  1型糖尿病开创性疗法初试结果显示安全

  文字稿

  一个通过重新训练人体免疫系统并减缓1型糖尿病恶化的开创性疗法首次试验结果为“安全”。导致患1型糖尿病的原因是胰腺内控制血糖水平的 Beta 细胞遭到破坏。研究人员们观察了在英国接受该免疫疗法的27名患者,其病情的恶化速度均呈现下降的趋势。但要想证实该疗法的功效,科学家们仍需进行更大规模的试验。请听报道。

  For now, there's no cure for type 1 diabetes. It’s caused by a rogue immune system destroying the beta cells in the pancreas that control blood sugar levels.

  The immunotherapy tries to stop that happening by training the immune system to protect the beta cells. It was shown to be safe in tests on 27 people at the National Institute for Health Research Biomedical Research Centre in London.

  There were also early signs the therapy was working. There were changes in the immune system and patients did not need to increase their insulin doses during the study. Professor Mark Peakman, who is leading the trial, said larger studies were still needed.

  The diabetes charity JDRF said even the early-stage findings were exciting and could lead to a time when people no longer have to inject insulin every day.
