As of April 2013, two primary approaches are being pursued in the search for a HIV cure: The first is gene therapy that aims to develop a HIV-resistant immune system for patients, and the second is being led by Danish scientists, who are conducting clinical trials to strip the HIV from human DNA and have it destroyed permanently by the immune ...
A small proportion of humans show partial or apparently complete innate resistance to HIV, the virus that causes AIDS. [1] The main mechanism is a mutation of the gene encoding CCR5, which acts as a co-receptor for HIV. It is estimated that the proportion of people with some form of resistance to HIV is under 10%. [2]
In 1996, Luigi Naldini and Didier Trono developed a new class of gene therapy vectors based on HIV capable of infecting non-dividing cells that have since then been widely used in clinical and research settings, pioneering lentivirals vector in gene therapy. [172] Jesse Gelsinger's death in 1999 impeded gene therapy research in the US.
Antiretroviral drugs are used to manage HIV/AIDS. Multiple antiretroviral drugs are often combined into a single pill in order to reduce pill burden. Some of these combinations are complete single-tablet regimens; the others must be combined with additional pills to make a treatment regimen.
Scientists use the lentivirus' mechanisms of infection to achieve a desired outcome to gene therapy. Lentiviral vectors in gene therapy have been pioneered by Luigi Naldini. [3] [4] Structure of a virion of HIV, a type of lentivirus. A membrane with protruding glycoproteins surrounds a capsid containing enzymes and the viral RNA genome.
The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. [1] There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy ...
How vectors work to transfer genetic material. Gene therapy utilizes the delivery of DNA into cells, which can be accomplished by several methods, summarized below. The two major classes of methods are those that use recombinant viruses (sometimes called biological nanoparticles or viral vectors) and those that use naked DNA or DNA complexes (non-viral methods).
HIV prevention refers to practices that aim to prevent the spread of the human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect their own health and the health of those in their community, or may be instituted by governments and community-based organizations as public health policies.
