The new centerpiece of the American effort to cure H.I.V. is the Martin Delaney Collaboratories, funded by the N.I.H. Launched in 2011, the collaborative was formulated as a way to link clinical labs, research facilities, and pharmaceutical companies. Federal support was set at seventy million dollars for the first five years, on the premise of coöperation and open communication among all parties. Salzwedel told me that the N.I.H. funded three applications. “Each was taking a different complementary approach to trying to develop a strategy to eradicate H.I.V,” he said: enhancing the patient’s immune system, manipulating the CCR5 gene, and destroying the reservoirs themselves. They represented different responses to the Siliciano thesis and to the lessons of Timothy Brown.

In the United States, HIV is spread mainly by having sex with or sharing drug injection equipment with someone who has HIV. To reduce your risk of HIV infection, use condoms correctly and consistently during sex, limit your number of sexual partners, and never share drug injection equipment. 

Treatment with HAART is not without complications. HAART is a collection of different medications, each with its own side effect profile. Some common side effects are nausea, headache, weakness, malaise, and fat accumulation on your back and abdomen (“buffalo hump,” lipodystrophy). When used long-term, these medications may increase the risk of heart attack by affecting fat metabolism.

Although the symptoms of immune deficiency characteristic of AIDS do not appear for years after a person is infected, the bulk of CD4+ T cell loss occurs during the first weeks of infection, especially in the intestinal mucosa, which harbors the majority of the lymphocytes found in the body.[99] The reason for the preferential loss of mucosal CD4+ T cells is that the majority of mucosal CD4+ T cells express the CCR5 protein which HIV uses as a co-receptor to gain access to the cells, whereas only a small fraction of CD4+ T cells in the bloodstream do so.[100] A specific genetic change that alters the CCR5 protein when present in both chromosomes very effectively prevents HIV-1 infection.[101]

If a person has been exposed to the virus, it is crucial that they get tested as soon as possible. The earlier HIV is detected, the more likely the treatment will be successful. A home testing kit can be used as well.

In June 2001, the United Nations (UN) General Assembly called for the creation of a “global fund” to support efforts by countries and organisations to combat the spread of HIV through prevention, treatment and care including buying medication.73

The weakening of the immune system associated with HIV infection can lead to unusual cancers like Kaposi’s sarcoma. Kaposi’s sarcoma develops as raised patches on the skin which are red, brown, or purple. Kaposi’s sarcoma can spread to the mouth, intestine, or respiratory tract. AIDS also may be associated with lymphoma (a type of cancer involving white blood cells).

HIV is passed from person to person through bodily fluids such as blood and semen. Once the virus enters your body, it attacks your immune system by destroying CD4 cells, which help keep you from getting sick.

There are more than 25 medications in six drug classes approved to treat HIV. The U.S. Department of Health and Human Services (HHS) recommends a starting regimen of three HIV medicines from at least two drug classes.

Seroconversion is the clearest evidence for an adaptive immune response to infection with HIV, but the generation of T lymphocytes responding to infected cells is thought by most workers in the field to be central in controlling the infection. Both CD8 cytotoxic T cells and TH1 cells specifically responsive to infected cells are associated with the decline in detectable virus after the initial infection. These T-cell responses are unable to clear the infection completely and can cause some pathology. Nevertheless, there is evidence that the virus itself is cytopathic, and T-cell responses that reduce viral spread should therefore, on balance, reduce the pathology of the disease.

HIV is transmitted when the virus enters the body, usually by infected immune cells in blood, vaginal fluids, or semen. Having the following risk factors increases the chance a person may become infected with HIV. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
