Variation in proteins helps to resist HIV attacks

According to a study by scientists at the Ragon Institute of Massachusetts General Hospital (USA), small variations in a protein may explain the mechanism of resistance to HIV / AIDS attacks for many years. A person is infected with this disease.

According to these scientists, for nearly two centuries, a small number of people infected with HIV (about 1 in 300 people) have the ability to naturally prevent the development of this virus in the immune system and because So it has maintained this virus at extremely low levels.

Through a study of the genome, scientists discovered about 300 addresses related to controlling the HIV / AIDS of the immune system. These addresses are in the six-chromosome encoding proteins called HLA.

Without using genome sequencing methods, scientists have developed a technique that clearly identifies amine acids that play an important role in controlling the immune system of HIV / ADS.

They discovered that the changes in these five acids in a protein called HLA-B are linked to the natural immunity mentioned above.
