This is shown in a new study from Karolinska Institutet, published in Gut Pathogens. The findings offer clues as to how the gut microbiome may influence the amount of virus that persists in the body.

Thu, 05 Sep 2024 09:06:04 +0200 https://news.ki.se/antiretroviral-therapies-impact-gut-microbiome-in-people-living-with-hiv A new study published in the journal Scientific Reports by researchers at Karolinska Institutet reveals that different antiretroviral therapies (ART) influence the gut and oral microbiome, as well as body mass index (BMI), in people living with HIV. The findings highlight the importance of considering microbiome changes when selecting ART regimens. Fri, 16 Aug 2024 08:53:43 +0200 https://news.ki.se/gut-microbes-can-affect-covid-vaccine-response Researchers from Karolinska Institutet have discovered that the gut microbiome can influence how well people respond to mRNA COVID vaccines. The study, published in the journal npj Biofilms and Microbiomes, suggests that certain bacteria in the gut can enhance the immune response to the vaccine, whereas other bacteria may weaken it. Thu, 04 Jan 2024 11:22:14 +0100 https://news.ki.se/study-provides-important-insights-for-hiv-treatment A study has shown that the distribution of HIV-1 subtypes in Sweden has changed a lot since the beginning of the AIDS epidemic. This is largely due to the migration of already infected people to Sweden. The study focused on people who migrated from Ukraine, so that the care can be adapted to their needs. The results provide important information for future analysis and treatment.

The discovery raises hopes of achieving the World Health Organization’s goal of eliminating the spread of infection from mother to child.

Fri, 16 Sep 2022 13:35:16 +0200 https://news.ki.se/new-biomarker-for-severe-covid-19 During the pandemic, it has become evident that people with cardiovascular disease and obesity are at much higher risk of developing very severe, even fatal COVID-19 disease. Researchers at Karolinska Institutet have identified some metabolic processes that SARS-CoV-2 uses to attack lung tissue. The results, which are published in Molecular & Cellular Proteomics, could one day be used to treat COVID-19, and potentially for other viruses like the Crimean-Congo hemorrhagic fever virus and HIV-1. Fri, 08 Oct 2021 08:34:06 +0200 https://news.ki.se/new-study-gives-hope-of-eliminating-mother-to-baby-transmission-of-hiv Anti-retroviral drugs are a vital tool in the prevention and treatment of HIV. A new study of pregnant women in Tanzania shows that life-long antiviral treatment also seems to prevent viral transmission from mother to baby. The results of the study, which was conducted in part by researchers at Karolinska Institutet and published in Lancet HIV, make a promising contribution to the WHO’s work with HIV prevention in low and middle-income countries.

Now research from Karolinska Institutet shows that the integrated virus mimics a specific chromatin structure that lets the virus sequence remain accessible while preventing production of new viruses. Fri, 31 Jan 2020 00:01:00 +0100 https://news.ki.se/new-discovery-on-the-activity-and-function-of-mait-cells-during-acute-hiv-infection In a new study published in Nature Communications, researchers at Karolinska Institutet show that MAIT cells (mucosa-associated invariant T cells), part of the human immune system, respond with dynamic activity and reprogramming of gene expression during the initial phase of HIV infection. The study fills a knowledge gap, as previously there has been a lack of awareness of the function of MAIT cells during this particular phase. Tue, 14 Jan 2020 11:00:00 +0100 https://news.ki.se/researchers-support-new-strategies-for-hiv-control The search for a cure to AIDS has partly focused on ways to eradicate infected cells. Now, new research from Karolinska Institutet in Sweden and the University of Pennsylvania in the U.S. shows that this approach may not be necessary for a functional cure. In a study focusing on a subset of HIV-positive individuals who can live with the virus without needing treatment, the researchers found that these people’s lymphocytes suppress the virus but do not kill off infected cells.
