Nobel Prize in Medicine: two Americans and a German ... - RFI

Medicine Nobel honors this year the discovery of the principle of transport of molecules within a cell. And to try to make it simpler, this trio of researchers elucidated the mystery of how a cell organizes its transport system so that the molecules are in the right place at the right time.

This is a very sophisticated these professors of biology, chemistry and medicine were able to study and decipher their separate mechanism.

Each cell is actually a small factory that produces and exports molecules. And it is precisely the signal that frees a molecule from one cell to another has been discovered.

important step to understand the process of healing from serious diseases such as diabetes, a condition in which insulin, the hormone that regulates blood sugar levels in the blood must be transported from cell to cell.

three researchers did not, however, conducted their research together. James Rothman is a professor of cell biology and chemistry. Randy Schekman teaches biology and Thomas Südhof teaches medicine.

fundamental concepts in this work is the concept of key-lock. We knew that the molecules must move from one place to another in the cell [...] What the researchers found is that there really is a concept of key-lock with vesicles. These small compartments have a set of keys, they must find the right locks and then the merger will make it happen and to mix compartments. This will help to understand how this is effectively monitored and that all does not mix together.
