THREE AMERICANS WON THE NOBEL PRIZE IN PHYSIOLOGY OR MEDICINE.

The three Americans won the Nobel Prize proclaimed by the Karolinska Institute in Stockholm. The winner names are James E.Rothman, 62, of Yale University, Randy W.Schekman, 64, of California University and Dr. Thomas C.Sudhof, 57, of Stanford University. They discovered the machinery that control how cells transfer major molecules in a cargo system which distributes to the right place at a time. The molecules surrounded the cells are said to be vesicles.

According to Dr. Rothman, said that he started his scientific profession when "your idea was the only limit, any risk could be taken no matter how difficult" and he faces five years of failure before the success. He was born in Haverhill, Mass. He studied vesicle transport in mammalian cells in the 1980's and 1990's. He worked at Princeton University, the Memorial Sloan-Kettering Cancer Center and Columbia University. Atlast, 2008 he united as a chairman of the department of cell biology in Yale University.

According to Dr. Schekman, exposed a set of genes that are needed

for vesicle traffic. The vesicle that covers the membrane which transfers the cargo between different compartments or fuse. This transport system initiate nerves and controls the release of hormones and enzymes. He was born in St. Paul, Minn. He studied his research in the 1970's. He studied in University of California, Los Angeles and Stanford where he finished his Ph.D in 1974. He united as a faculty at Berkeley in 1976.

According to Dr. Sudhof, was born in Gottingen, West Germany. He was a United State citizen. He studied  neurotransmission, which helps the process of nerve cells connected with other cells in the brain. He graduate of the Georg- August- University in Gottingen and in 1983 he transfer to the University of Texas SouthWestern Medical Center in Dallas. He was united as a professor of molecular and cellular physiology at Stanford.
