Transplantation Research: Making Miracles Happen

TIRN Brochure

The American Society of Transplantation (AST) Transplantation and Immunology Research Network (TIRN)℠ was created to connect hundreds of physicians and scientists who have dedicated their lives to advancing the research necessary to improve and save lives. Pharmaceutical companies and private foundations are also a part of the research network, and offer valuable resources for advancing transplantation and immunology research. We also invite patients and the general public to consider themselves part of this network as well.

Since the first organ transplant in 1954, the gift of life has become a reality for hundreds of thousands of people. With over 250,000 Americans living today with functioning transplants, transplantation is one of the most effective therapies for end-stage diseases such as kidney and liver failure. In fact, successful kidney transplants directly save our country's health care system over $12 billion every year by removing those recipients from other treatment regimens like dialysis.

It has never been more vital for all of us to understand what research can do to advance the field of transplantation, and how we can support that research. The number of people suffering from diseases that damage organs is growing. Nearly one-third of American adults have high blood pressure, nearly 30 million have diabetes and 90 million are obese. The increasing rates of obesity and diabetes in the U.S. is putting tens of thousands of Americans at risk for liver and heart failure. Organ transplantation is more common that you might think, and touches more lives than most can imagine.
