📣 Published in The Lancet HIV today: a call for investment in HIV cure research, by an international coalition of researchers, donors and people with #HIV. "The question is no longer whether a cure is possible, but how quickly we can develop safe, accessible treatments"

"Most preprints could be of near-equal value to peer-reviewed journal articles before any revisions are made to them. Current forms of peer review create significant delays for seemingly marginal gains."

40 years of HIV discovery: the virus responsible for AIDS is identified on May 20, 1983 In 1983, HIV -the virus responsible for AIDS- was isolated by virologists from the Institut Pasteur. A first observation with a microscope in February was confirmed in May 83 by a publication in Scien...

🗓️ On this day in 1983, virologists at Institut Pasteur published research, identifying & isolating the #HIV virus.

This historic breakthrough by Past IAS President Françoise Barré-Sinoussi & Luc Montagnier sparked decades of progress in the HIV response.

Our results support a key role of NK cells in the control of HIV-1 off ART and may guide the development of new immunotherapies against HIV-1. Our results also highlight that our understanding of natural HIV-1 infection may not fully apply to the context of ART interruption

Paradoxically, one of these factors, HLA-B*35 is associated with a rapid progression to AIDS if the treatment is not initiated. It is truly exciting that early ART initiation might have transformed an initial desfavorable situation into an enhanced potential to achieve HIV remission.

In retrospective analysis we found that the presence of this genetic combination was associated with a better probability of maintaining HIV controlled after ART discontinuation among people who started the treatment during the first weeks following infection.

NIH Grant Cuts Threaten Progress in HIV Prevention and Treatment Funding cuts particularly target studies involving sexual minorities, transgender people and people of color.

While pharmaceutical companies pay for trials of their own drugs, government-funded studies are crucial because they can look at the bigger picture. The ACTG -- which now has its funding suspended by NIH -- been supporting HIV research for nearly 40 years. Here are a few of its notable studies.🧵

Statin treatment by itself will not be sufficient to promote HIV control in the context of ART interruption, but CD8 T cell in vivo metabolic reprogramming with rosuvastatin could be used to potentiate the efficacy of other immunotherapies aiming at HIV cure or remission

We identified several changes in the survival and functionality of CD8 T cells that coincided with rosuvastatin treatment. These parameters went back to baseline levels upon cessation of the treatment.

In our new study we show that CD8 T cell reprogramming is also achievable in vivo. We used bio-banked samples from the CESAR trial where people on ART (without metabolic disorders but subpotimal immune reconstitution) received 3 months of rosuvastatin treatment to decrease activation/inflammation.
