World Health United States made a revolution to manipulate genetically pig tissue transplants to overcome the threat of disease in humans. In the experiment, tissue frompig meat taken specifically to help people with diabetes, brain diseases and blindness. However, experts from the UK to challenge the findings and worried about the securityaspect of this experiment. His worry is that retroviruses can move from pigs to humansand trigger a new pandemic and specific infections such as HIV.
Excerpted from the Independent, October 24, 2011,experts from the Thomas StarzlTransplantation Institute, University of Pittsburgh, Pennsylvania, United States stated that they had made great strides namely xenotransplantation or the use of animal tissues andorgans to replace human tissues or organs.
Prior to this, in the mid-1990s, Imutran, the Cambridge biotechnology company, claims to be the first company in the world to successfully move a pig hearts into monkeys and allows transpalansi special cross.
However, the immune system becomes a difficult problem, exceeding expectations andmagnitude of security concerns about it. Although possible, the problem persists,including the loss of the transplanted cells, blood clots and other problems of rejection.
But now researchers claim, genetically engineered pigs that can address this problem will soon be available and make animal-to-human transplantation trials are becoming increasingly 'close'. U.S. scientists who ignore the expressed concerns of retroviruses, there is no great risk.
The statement was opposed by Robin Weiss, professor of virology at University College,London, who is also a retrovirus. "It takes a strict monitoring to patients to ensure patients are not exposed to anything from a pig," he said.
Hi there, what a great web blog. I spend several hours on the net reading sites on various topics. And, I really would like to praise you for writing such a fabulous article.
