MOSCOW: A group of scientists from Scripps Research Institute (TSRI) discovered that immune cells able to conquer HIV are present in the human body. Some people infected with HIV can produce antibodies that effectively neutralize many strains of the dangerous, rapidly mutating virus. A healthy person, however, would need to be immunized with special antigens in order to produce the required antibodies. The success of a potential vaccine depends on the ability of the immunogen to bind with cells called B-lymphocytes and to activate them so that they produce antibodies. A team of scientists wrote in a new study published in Science magazine on March 24 that most people have so-called “embryo” precursor cells in their bodies which can generate VRC01 antibodies needed to conquer HIV cells.
