The human immunodeficiency viruses (HIV) are two species of Lentivirus that infect humans. Over time, they cause acquired immunodeficiency syndrome (AIDS), a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, the average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype.
Peter H. Duesberg is a German-American molecular biologist and a professor of molecular and cell biology at the University of California, Berkeley. He is known for his early research into the genetic aspects of cancer. He is a proponent of AIDS denialism, the claim that HIV does not cause AIDS.
Zidovudine (ZDV), also known as azidothymidine (AZT), was the first antiretroviral medication used to prevent and treat HIV/AIDS. It is generally recommended for use in combination with other antiretrovirals. It may be used to prevent mother-to-child spread during birth or after a needlestick injury or other potential exposure. It is sold both by itself and together as lamivudine/zidovudine and abacavir/lamivudine/zidovudine. It can be used by mouth or by slow injection into a vein.
HIV/AIDS denialism is the belief, despite conclusive evidence to the contrary, that the human immunodeficiency virus (HIV) does not cause acquired immune deficiency syndrome (AIDS). Some of its proponents reject the existence of HIV, while others accept that HIV exists but argue that it is a harmless passenger virus and not the cause of AIDS. Insofar as they acknowledge AIDS as a real disease, they attribute it to some combination of sexual behavior, recreational drugs, malnutrition, poor sanitation, haemophilia, or the effects of the medications used to treat HIV infection (antiretrovirals).
The year 1983 in science and technology involved many significant events, as listed below.
Luc Montagnier was a French virologist and joint recipient, with Françoise Barré-Sinoussi and Harald zur Hausen, of the 2008 Nobel Prize in Physiology or Medicine for his discovery of the human immunodeficiency virus (HIV). He worked as a researcher at the Pasteur Institute in Paris and as a full-time professor at Shanghai Jiao Tong University in China.
AIDS is caused by a human immunodeficiency virus (HIV), which originated in non-human primates in Central and West Africa. While various sub-groups of the virus acquired human infectivity at different times, the present pandemic had its origins in the emergence of one specific strain – HIV-1 subgroup M – in Léopoldville in the Belgian Congo in the 1920s.
The genome and proteins of HIV (human immunodeficiency virus) have been the subject of extensive research since the discovery of the virus in 1983. "In the search for the causative agent, it was initially believed that the virus was a form of the Human T-cell leukemia virus (HTLV), which was known at the time to affect the human immune system and cause certain leukemias. However, researchers at the Pasteur Institute in Paris isolated a previously unknown and genetically distinct retrovirus in patients with AIDS which was later named HIV." Each virion comprises a viral envelope and associated matrix enclosing a capsid, which itself encloses two copies of the single-stranded RNA genome and several enzymes. The discovery of the virus itself occurred two years following the report of the first major cases of AIDS-associated illnesses.
Flossie Wong-Staal was a Chinese-American virologist and molecular biologist. She was the first scientist to clone HIV and determine the function of its genes, which was a major step in proving that HIV is the cause of AIDS. From 1990 to 2002, she held the Florence Riford Chair in AIDS Research at the University of California, San Diego (UCSD). She was co-founder and, after retiring from UCSD, she became the chief scientific officer of Immusol, which was renamed iTherX Pharmaceuticals in 2007 when it transitioned to a drug development company focused on hepatitis C and continued as chief scientific officer.
Neutral alpha-glucosidase C is an enzyme that in humans is encoded by the GANC gene.
Neutral alpha-glucosidase AB is an enzyme that in humans is encoded by the GANAB gene.
Alpha-mannosidase 2 is an enzyme that in humans is encoded by the MAN2A1 gene.
Robert Charles Gallo is an American biomedical researcher. He is best known for his role in establishing the human immunodeficiency virus (HIV) as the infectious agent responsible for acquired immune deficiency syndrome (AIDS) and in the development of the HIV blood test, and he has been a major contributor to subsequent HIV research.
Françoise Barré-Sinoussi is a French virologist and Director of the Regulation of Retroviral Infections Division and Professor at the Institut Pasteur in Paris, France. Born in Paris, France, Barré-Sinoussi performed some of the fundamental work in the identification of the human immunodeficiency virus (HIV) as the cause of AIDS. In 2008, Barré-Sinoussi was awarded the Nobel Prize in Physiology or Medicine, together with her former mentor, Luc Montagnier, for their discovery of HIV. She mandatorily retired from active research on August 31, 2015, and fully retired by some time in 2017.
Jean-Claude Chermann is a French virologist who managed the research team which, by 1983, under the administrative supervision of Luc Montagnier, had discovered the virus associated with AIDS. Whereas second author of this initial publication and obviously involved as team manager in this discovery, he had been omitted from the Nobel Prize attributed to its colleagues. In 2008, as chairman of the support committee for the attribution of the Nobel Prize in medicine to Jean-Claude Chermann, Bernard Le Grelle, a political consultant, campaigned for the official recognition of this oversight with the Nobel committee by bringing together more than 700 doctors, professors and scientists . The virus was named lymphadenopathy-associated virus, or LAV. A year later, a team led by Robert Gallo of the United States confirmed the discovery of the virus, but renamed it human T-lymphotropic virus type III (HTLV-III).
The primate T-lymphotropic viruses (PTLVs) are a group of retroviruses that infect primates, using their lymphocytes to reproduce. The ones that infect humans are known as human T-lymphotropic virus (HTLV), and the ones that infect Old World monkeys are called simian T-lymphotropic viruses (STLVs). PTLVs are named for their ability to cause adult T-cell leukemia/lymphoma, but in the case of HTLV-1 it can also cause a demyelinating disease called tropical spastic paraparesis. On the other hand, newer PTLVs are simply placed into the group by similarity and their connection to human disease remains unclear.
A virus closely related to HTLV-I, human T-lymphotropic virus 2 (HTLV-II) shares approximately 70% genomic homology with HTLV-I. It was discovered by Robert Gallo and colleagues.
The Perth Group is a group of HIV/AIDS denialists based in Perth, Western Australia who claim, in opposition to the scientific consensus, that the existence of HIV is not proven, and that AIDS and all the "HIV" phenomena are caused by changes in cellular redox due to the oxidative nature of substances and exposures common to all the AIDS risk groups, and are caused by the cell conditions used in the "culture" and "isolation" of "HIV".
William A. Haseltine is an American scientist, businessman, author, and philanthropist. He is known for his groundbreaking work on HIV/AIDS and the human genome.
James M. Oleske is an American pediatrician and HIV/AIDs researcher who is the emeritus François-Xavier Bagnoud (FXB) Professor of Pediatrics at Rutgers New Jersey Medical School in Newark, New Jersey. He is best known for his pioneering work in identifying HIV/AIDS as a pediatric disease, and treating and researching it beginning in the 1980s. He published one of the first articles identifying HIV/AIDS in children in JAMA in 1983 and was a co-author of one of the articles by Robert Gallo and others identifying the virus in Science in 1984.
