What is HIV? (Definition HIV / AIDS)

According to the U.S. Department of Health and Human Services, HIV stands for human immunodeficiency virus. If left untreated, HIV can lead to the disease AIDS (acquired immunodeficiency syndrome).

Unlike some other viruses, the human body can’t get rid of HIV completely. So once you have HIV, you have it for life.

HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. If left untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get infections or infection-related cancers. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last state of HIV infection.

HIV News: Food is medicine for HIV-positive and Type 2 diabetes patients

(SOURCE: UNIVERSITY OF CALIFORNIA - SAN FRANCISCO) - HIV-positive people who received healthy food and snacks for six months were more likely to adhere to their medication regimens, and they, as well as people with type 2 diabetes, were less depressed and less likely to make trade-offs between food and healthcare, according to a new study led by researchers at UC San ...

HIV Treatment News: Antibody combination puts HIV on the ropes

(SOURCE: ROCKEFELLER UNIVERSITY) - Without antiretroviral drug treatment, the majority of people infected with HIV ultimately develop AIDS, as the virus changes and evolves beyond the body's ability to control it. But a small group of infected individuals--called elite controllers--possess immune systems capable of defeating the virus. They accomplish this by manufacturing broadly neutralizing antibodies, which can take down multiple forms of ...

HIV Treatment News: Successful antibody trial in HIV-infected individuals

(SOURCE: GERMAN CENTER FOR INFECTION RESEARCH) - A research team led by investigators of the Rockefeller University in New York and Prof Florian Klein, University Hospital Cologne and German Center for Infection Research (DZIF), has tested a new HIV neutralising antibody, called 10-1074, in humans. The results of the trial have just been published in Nature Medicine. Over the last years, a ...

AIDS Research News: What Does it Take for an AIDS Virus to Infect a Person?

(SOURCE: UNIVERSITY OF PENNSYLVANIA SCHOOL OF MEDICINE) - Upon sexual exposure, the AIDS virus must overcome some mighty barriers to find the right target cell and establish a new infection. It must traverse the genital mucosa and squeeze through tightly packed epithelial cells meant to keep invaders out. And then it must thwart the initial immune-system alarm bell in the form of ...

HIV Research News: SALK SCIENTISTS CRACK THE STRUCTURE OF HIV MACHINERY

(SOURCE: SALK INSTITUTE) - Antiviral therapy could be improved with the newly uncovered atomic-level details. Salk Institute scientists have solved the atomic structure of a key piece of machinery that allows HIV to integrate into human host DNA and replicate in the body, which has eluded researchers for decades. The findings describing this machinery, known as the “intasome,” appear January 6, 2017, ...

HIV Treatment News: Protein that activates immune response harms body’s ability to fight HIV

(SOURCE: UCLA) - UCLA-led researchers suggest that blocking type I interferon may help combat the virus that causes AIDS. In findings they call counterintuitive, a team of UCLA-led researchers suggests that blocking a protein, which is crucial to initiating the immune response against viral infections, may actually help combat HIV. Findings from a study in animals appear to demonstrate that temporarily blocking ...

HIV Treatment News: CRISPR screening identifies potential HIV treatment targets

(SOURCE: MASSACHUSETTS GENERAL HOSPITAL) - Targeting human genes required for viral reproduction but not for T cell survival would avoid inducing treatment resistance.  Investigators from the Ragon Institute of MGH, MIT and Harvard and the Broad Institute of MIT and Harvard have used the revolutionary new gene-editing technology CRISPR-Cas9 to identify three promising new targets for treatment of HIV infection. In their report receiving ...

HIV Research News: Researchers in the HIV Extinction Project at UCLA collaborate to cure AIDS

(SOURCE: UCLA) Enrique Rivero | December 01, 2016 -  It’s the single-largest project of its type at the UCLA AIDS Institute. As we observe the 29th World AIDS Day, people infected with HIV are living longer than ever and progress continues in the fight against the disease that was a death sentence decades ago. Some of those positive developments resulted from ...

HIV Treatment News: New Antiretroviral Drugs Could Potentially Reduce Chances of HIV Sexual Transmission According to Research

(IDIBELL-BELLVITGE BIOMEDICAL RESEARCH INSTITUTE) According to a recent press release, more than 2 million people got infected by human immunodeficiency virus (HIV) in 2015, being sexual transmission the main channel of infection. Researchers from the Infections of the Respiratory Tract and in Immunocompromised Patients group of the Bellvitge Biomedical Research Institute (IDIBELL), led by Dr. Daniel Podzamczer, have evaluated the ...
