Study explores factors associated with parents' acceptance of SGM adolescents using PrEP

Since its approval in 2012, HIV pre-exposure prophylaxis, or PrEP, has shown promise in reducing HIV infection rates by preventing infection in high-risk HIV-negative people. However, research shows that only around three percent of sexual and gender minority (SGM) adolescents who are eligible for PrEP have used it.

Study identifies cell type crucial for successful immunotherapies for chronic viral infections

An international study led by researchers from the Infection Biology Laboratory at the UPF Department of Medicine and Life Sciences (MELIS) establishes that one type of dendritic cells is crucial for the success of immunotherapeutic treatments to control chronic viral infections.

Study reveals the mechanisms that prevent effective cancer cell death

Cancer is a disease driven by gene mutations. These mutated genes in cancer fall into two major categories: tumor suppressors and oncogenes. Mutations in tumor suppressor genes can allow tumors to grow unchecked – a case of no brakes – while mutations in oncogenes can activate cell proliferation, pushing the gas pedal all the way to the floor.

Extracts from two common wild plants block SARS-CoV-2 from entering human cells

Two common wild plants contain extracts that inhibit the ability of the virus that causes COVID-19 to infect living cells, an Emory University study finds.

A treatment strategy to hasten cancer cell death

Gene mutations are the cause of cancer. Tumor suppressors and oncogenes are the two main groups of these altered genes in cancer. Mutations in oncogenes can drive cell proliferation, pushing the gas pedal to the floor, whereas mutations in tumor suppressor genes can cause tumors to grow unchecked—a situation in which there is no control.

Psychological trauma related to HIV could make it difficult to end the AIDS epidemic

Failing to address the psychological trauma experienced by many older people living with HIV/AIDS will make it difficult, if not impossible, to end the epidemic, according to a Rutgers study.

Promotional spending share allocated to consumer advertising higher for drugs with low added benefit

A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health found that the share of promotional spending allocated to consumer advertising was on average 14.3 percentage points higher for drugs with low added benefit compared to drugs with high added benefit.

Clinically approved fungal vaccine protects against fungal infections

A new vaccine developed by the University of Georgia might be the first clinically approved immunization to safeguard against invasive fungal infections, which are becoming more common as antifungal drug resistance grows.

UNC research describes another layer to the challenge of HIV latency

When people living with HIV take antiviral therapy (ART), their viral loads are driven so low that a standard blood test cannot detect the virus.

MicroRNA’s influence on lupus disease inflammation

Researchers from Nagoya University’s Graduate School of Medicine in Japan have uncovered how microRNA (miRNA) affects inflammation in mice with lupus. They discovered two downregulated miRNAs in the disease along with a rare circumstance where several miRNAs control the same set of genes.

New revelations on the immune system’s defenses against infections

Cells competing for a place in a germinal center confront a tough admissions process. Germinal centers, which form following exposure to a pathogen or vaccine, serve as a kind of immune system training academy, assisting B cells in refining their response to the threat.

Detecting the extent of natural selection over time

Institut Pasteur, Université Paris Cité, the CNRS, and the Collège de France researchers have employed paleogenomics to trace 10,000 years of human immune system evolution. They examined the genomes of over 2,800 individuals who lived in Europe over the past 10 millennia.

HIV’s covert methods of evading treatment and immunity

According to Duke Health researchers, the human immunodeficiency virus (HIV) appears to be driven into a latent state, lurking in cells only to erupt once more. This immune response likely evolved to help fight infections.

Recognizing how the HIV-1 evades immune system

According to a recent study led by Andrés Finzi, a professor at the Université de Montréal and researcher at the CHUM Research Centre, the type of virus used as a model to study the effectiveness of non-neutralizing antibodies against the virus that causes AIDS, has a crucial role to play.
