The Env polyprotein gp goes through the endoplasmic reticulum and is transported to the Golgi apparatus where it is cleaved by furin resulting in the two HIV envelope glycoproteins, gp41 and gp The Gag p55 and Gag-Pol p polyproteins also associate with the inner surface of the plasma membrane along with the HIV genomic RNA as the forming virion begins to bud from the host cell.
The budded virion is still immature as the gag polyproteins still need to be cleaved into the actual matrix, capsid and nucleocapsid proteins.
This cleavage is mediated by the packaged viral protease and can be inhibited by antiretroviral drugs of the protease inhibitor class. The various structural components then assemble to produce a mature HIV virion.
The classical process of infection of a cell by a virion can be called "cell-free spread" to distinguish it from a more recently recognized process called "cell-to-cell spread".
Firstly, an infected T cell can transmit virus directly to a target T cell via a virological synapse. HIV differs from many viruses in that it has very high genetic variability.
This complex scenario leads to the generation of many variants of HIV in a single infected patient in the course of one day.
When simultaneous infection occurs, the genome of progeny virions may be composed of RNA strands from two different strains. This hybrid virion then infects a new cell where it undergoes replication.
As this happens, the reverse transcriptase, by jumping back and forth between the two different RNA templates, will generate a newly synthesized retroviral DNA sequence that is a recombinant between the two parental genomes.
The closely related simian immunodeficiency virus SIV has evolved into many strains, classified by the natural host species. These hosts have adapted to the presence of the virus,  which is present at high levels in the host's blood, but evokes only a mild immune response,  does not cause the development of simian AIDS,  and does not undergo the extensive mutation and recombination typical of HIV infection in humans.
In contrast, when these strains infect species that have not adapted to SIV "heterologous" or similar hosts such as rhesus or cynomologus macaques , the animals develop AIDS and the virus generates genetic diversity similar to what is seen in human HIV infection.
Nef 's function in non-pathogenic forms of SIV is to downregulate expression of inflammatory cytokines , MHC-1 , and signals that affect T cell trafficking.
Without this function, T cell depletion is more likely, leading to immunodeficiency. Co-infection with distinct subtypes gives rise to circulating recombinant forms CRFs.
In , the last year in which an analysis of global subtype prevalence was made, Many HIV-positive people are unaware that they are infected with the virus.
Specimens that are repeatedly ELISA-reactive occasionally provide an indeterminate western blot result, which may be either an incomplete antibody response to HIV in an infected person or nonspecific reactions in an uninfected person.
HIV deaths other than U. Although IFA can be used to confirm infection in these ambiguous cases, this assay is not widely used. In general, a second specimen should be collected more than a month later and retested for persons with indeterminate western blot results.
Although much less commonly available, nucleic acid testing e. In these situations, a second specimen is collected and tested for HIV infection.
Modern HIV testing is extremely accurate, when the window period is taken into consideration. This gives rise to four possible scenarios:.
This research includes behavioral health interventions , such as research into sex education , and drug development , such as research into microbicides for sexually transmitted diseases , HIV vaccines , and anti-retroviral drugs.
Previously it was said the chance of transmission was "very low" or "negligible" The "Swiss Statement". In total from the four studies, couples were enrolled over four continents and , acts of condomless sex were reported; there were zero phylogenetically linked transmissions of HIV where the positive partner had an undetectable viral load.
Our results provide a similar level of evidence on viral suppression and HIV transmission risk for gay men to that previously generated for heterosexual couples and suggest that the risk of HIV transmission in gay couples through condomless sex when HIV viral load is suppressed is effectively zero.
This result is consistent with the conclusion presented by Anthony S. Daily antiviral e. The first news story on "an exotic new disease" appeared May 18, in the gay newspaper New York Native.
In the beginning, the CDC did not have an official name for the disease, often referring to it by way of the diseases that were associated with it, for example, lymphadenopathy , the disease after which the discoverers of HIV originally named the virus.
Gallo admitted in that the virus he claimed to have discovered in was in reality a virus sent to him from France the year before.
Montagnier's group isolated a virus from a patient presenting with swelling of the lymph nodes of the neck and physical weakness , two classic symptoms of primary HIV infection.
Contradicting the report from Gallo's group, Montagnier and his colleagues showed that core proteins of this virus were immunologically different from those of HTLV-I.
Montagnier's group named their isolated virus lymphadenopathy-associated virus LAV. Another group working contemporaneously with the Montagnier and Gallo groups was that of Dr.
Both HIV-1 and HIV-2 are believed to have originated in non-human primates in West-central Africa, and are believed to have transferred to humans a process known as zoonosis in the early 20th century.
HIV-1 is thought to have jumped the species barrier on at least three separate occasions, giving rise to the three groups of the virus, M, N, and O.
There is evidence that humans who participate in bushmeat activities, either as hunters or as bushmeat vendors, commonly acquire SIV.
It is thought that several transmissions of the virus from individual to individual in quick succession are necessary to allow it enough time to mutate into HIV.
Specific proposed high-risk transmission channels, allowing the virus to adapt to humans and spread throughout the society, depend on the proposed timing of the animal-to-human crossing.
Genetic studies of the virus suggest that the most recent common ancestor of the HIV-1 M group dates back to circa An alternative view—unsupported by evidence—holds that unsafe medical practices in Africa during years following World War II, such as unsterile reuse of single-use syringes during mass vaccination, antibiotic, and anti-malaria treatment campaigns, were the initial vector that allowed the virus to adapt to humans and spread.
