The researchers worldwide, working privately and with government support, are looking forward in the treatment of HIV, is the virus that can lead to AIDS. However, it is important to understand that such advances will occur slowly and cure of HIV is probably not a reality in the near future. Viruses are difficult to eradicate, and the hope of a vaccine may be the next big breakthrough in the fight against HIV and AIDS.
Advances in treatment
Recent years have seen a proliferation of new drugs that stop HIV in different ways with respect to their predecessors and offer hope to people who have developed other anti-retroviral drug resistance. These include fusion inhibitors that prevent HIV to fuse with host cells; antagonistic co-receptors of chemokines, which bind a co-receptor for HIV to white blood cells; incorporation inhibitors which interrupt the integration function (HIV enzyme uses to integrate its genetic information into the host cell). While these medications offer improved treatment for many people, no antiretroviral drugs can cure HIV.
There are a number of organizations have come together to promote the work of finding an effective vaccine against HIV. These include network testing for HIV vaccine (Vaccine Trials Network [HVTN]) and the company’s global HIV vaccines (Global HIV Vaccine Enterprise). Both organizations promote international cooperation in research funding and direct realization of this research. Although a vaccine could not cure HIV in people already infected could stop new infections, which is an advance important in controlling the epidemic.
It was reported in July 2009 that a team of researchers at the University of Western Ontario was presenting a vaccine for HIV for approval of drug administration and board of the United States (U.S. Food and Drug Administration) for testing in humans. The vaccine is called SAV001-H and has been proven safe in animals. Even if the vaccine is approved for testing and is found to be safe, it may take a while before it is available to the public.
University of Texas team
In 2008, a group of researchers from the University of Texas Medical School announced that they had found a new way to target the HIV. By using enzyme antibody, the team believes that can develop a drug and possible vaccine for HIV; these indicate a part of HIV mutates not a main concern to treat HIV. Although locating a static part of the HIV marks an important advance in the research, these findings will require much more research and time to give a vaccine or medication.
Publication The Advocate reported in 2007 that a German team had announced the development of an enzyme called Tre which can remove the HIV-1 (the form of the virus that causes most infections outside West Africa) of the host cells. This is one of the few developments that offers hope of a cure for people already infected with HIV. However, as with other findings for this treatment is effective even if and approved for use in humans, would not be available for some time.
