The reason they need it: Their own insulin-producing islet cells, located in the pancreas, aren’t working. Now, scientists across the US are racing to develop effective ways to transplant new islet cells in people with diabetes—an alternative that could make daily life easier and lower risk for insulin side effects like dangerous low blood sugar episodes. 

James Collip refined Banting and Best’s insulin extraction and purification method. The new substance was tested in the first human in 1922. 14-year old Leonard Thompson was in a critical condition. He was given an insulin injection in his buttocks. This had a negative affect on him and he grew sicker. Collip worked to improve the insulin’s quality and Thompson received another injection soon after. This time, it lowered his blood sugar and saved his life.
Diabetes mellitus is a chronic disease, for which there is no known cure except in very specific situations.[75] Management concentrates on keeping blood sugar levels as close to normal, without causing low blood sugar. This can usually be accomplished with a healthy diet, exercise, weight loss, and use of appropriate medications (insulin in the case of type 1 diabetes; oral medications, as well as possibly insulin, in type 2 diabetes).

So far, none of the hypotheses accounting for virus-induced beta cell autoimmunity has been supported by stringent evidence in humans, and the involvement of several mechanisms rather than just one is also plausible.

The results of his medical tests are still being analyzed, Darkes said, but he hasn't needed insulin injections for a year and a half. "It took a long time to sink in," he noted. But Darkes is confident he no longer has type 1 diabetes. He said that doctors told him that he has a "rare" gene that somehow facilitated his cure. "I'm the only one who carries [the gene], at the moment," and there's no further explanation so far, he said.
