British Scientists Discover the gel to Prevent Transmission of AIDS

War against Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS), continues to progress. A number of scientists led by Professor Robin Offord and Olivier Hartley of the University of Geneva, Switzerland, recently, successfully developed a kind of molecule that is believed to protect humans from HIV / AIDS.
A protein from the protein-enhanced human immune system was shown to protect female monkeys from the AIDS virus. The plan, a formula was developed in the form of gels that can be used humans to prevent sexual transmission of HIV. In laboratory tests, the compound was able to protect cells from virus attacks during a full day.

This means, in theory, people who use chemical gels that are protected from attack by HIV / AIDS at least 24 hours before having sex. Maximum in the next year, the side effects of human gel can already known. Then, the drug was tested prevention efficacy rate in preventing HIV infection / AIDS in high-risk groups.

Furthermore, Offord and colleagues will develop a cheaper way and easy to make these molecules. As we all know, HIV can produce their own cells in the human bloodstream, the cells are white blood cells (leukocytes). Blood cells that normally fight white when attacked by viruses, not to fight HIV.

This can occur because HIV is a retrovirus or a virus type that can breed in human blood. Later, the virus has attacked one of the cell types of white blood cells, including lymphocytes, called "T-4" or T-helper (helper) who is also known as CD-4 cells. To be able to infect the CD-4, HIV requires receptor - one or a group of nerve cells and other cells that function to recognize certain stimuli from outside or within the body - called CCR5.

According to research Offord and his team, people who have a lot of CD-4 cells with little CCR5 is almost certainly safe from HIV infection. Cell acts as the immune system chemical messengers called regulated on activation normal T Expressed and secreted (Rantes). Well, Rantes is being developed by a team led Offord to prevent HIV infection.
