Three Toronto scientists have developed an organ transplant procedure
that could, among its many benefits, reverse diabetes.
The procedure was developed by Bernard Leibel, Julio Martin and Walter
Zingg at the University of Toronto and the Hospital for Sick Children.

The story of their work began in 1978, when they delved into research

thereby raise the threshold of rejection.

Encouraged by their first results, Leibel, Martin, and Zingg decided to
repeat the experiment with rats with much stronger immune barriers
(higher levels of rejection). Seven rats out of nine were cured. "We set
up a protocol and worked patiently with small numbers," says Leibel, "but
the results are indisputable."

In addition to reversing diabetes, there are two other benefits to the
pre-treatment procedure, according to the scientists. The first is that
the pancreas produces all the other hormones of a normal pancreas, not
just insulin. The second benefit is that the transplant recipient doesn't
have to take immunosuppressive drugs, which are so toxic for diabetics.
