Researchers discover how SARS-CoV-2 hijacks human cell machinery to blunt immune response

Researchers at University of California San Diego School of Medicine have discovered one way in which SARS-CoV-2, the coronavirus that causes COVID-19, hijacks human cell machinery to blunt the immune response, allowing it to establish infection, replicate and cause disease.

Non-traditional risk factors impact African American patients with coronary artery disease

A retrospective analysis of risk factors for coronary artery disease (CAD) in young African American patients is being presented today at the Society for Cardiovascular Angiography and Interventions 2021 Virtual Scientific Sessions.

Scientists identify blood cells most likely to be targeted by HIV during a real-life infection

In the 40-some years since the beginning of the HIV/AIDS epidemic, scientists have learned a lot about the virus, the disease, and ways to treat it. But one thing they still don't completely understand is which exact cells are most susceptible to HIV infection.

Horizontal transmission route is responsible for HTLV-1 uveitis

Human T-cell lymphotropic virus type-1 (HTLV-1) is a retrovirus similar to human immunodeficiency virus (HIV) and has mostly been thought to be transmitted vertically (mother-to-child), or horizontally (sexually or parenterally (e.g. via blood transfusion)).

ANTICOV clinical trial to test new treatment for people with mild-to-moderate COVID-19 in Africa

The ANTICOV clinical trial, conducted in 13 African countries, has started the recruitment of participants to test a new drug combination, nitazoxanide + ciclesonide, to treat people with mild-to-moderate COVID-19 before their cases become severe.

Scientists uncover an important clue to the conundrum of mother-to-child HIV transmission

Each year over 150,000 infants worldwide are infected with HIV in the womb, at birth, or through breastfeeding.

Stigma, discrimination impede engagement in HIV prevention and treatment

Stigma and discrimination, such as homophobia and racism, impede engagement in HIV prevention and use of biomedical tools for treatment in both HIV-negative and HIV-positive gay and bisexual men, according to a Rutgers study.

Host cell transmembrane protein MARCH8 targets lysine residues to inhibit SARS-CoV-2 and other viruses

A new study deals with the inhibitory activity of a membrane protein that has broad-spectrum activity against multiple viruses, showing that this is due to its effect on cytoplasmic lysine residue incorporation into replicating virions.

Fighting malaria in 2021: Where are we now and where are we going?

In support of World Malaria Day, News-Medical spoke to Dr. Laurence Slutsker, an internationally recognized expert in malaria, about fighting this disease in 2021.

Disruptions to essential health services due to COVID-19 pandemic persist in 90% of countries

The second round of a World Health Organization "pulse survey" reveals that over one year into the COVID-19 pandemic, substantial disruptions persist, with about 90% of countries still reporting one or more disruptions to essential health services, marking no substantial global change since the first survey conducted in the summer of 2020.

Only one vaccine is OK for older teens. It’s also the hardest to manage in rural America.

As states expand covid-19 vaccine eligibility to allow shots for 16- and 17-year-olds, teens in rural America may have trouble getting them.

Celastrol shows potential anti-SARS-CoV-2 activity

A new study published on the bioRxiv* preprint server focuses on the in-silico predictions to repurpose existing drug compounds, that may have the ability to reverse the SARS-CoV-2 gene expression induced in host cells.

New Phase 3 trial of therapeutics begins enrolling severely ill hospitalized COVID-19 patients

A new Phase 3 trial to test the safety and efficacy of therapeutics for COVID-19 has begun enrolling patients hospitalized with life-threatening cases of COVID-19, including those with acute respiratory failure.

Patients with high HIV risk are aware of preventative pill, but few are using it

Cisgender sexual minority men and transgender women are aware of pre-exposure prophylaxis (PrEP), a daily pill for HIV-negative people to prevent HIV infection, but few are currently taking it, according to researchers at Rutgers.

Characterization of lab-produced neutralizing antibodies targeting SARS-CoV-2

A new study led by Hans-Martin Jäck of the Friedrich-Alexander University Erlangen-Nuremberg in Germany engineered clusters of neutralizing monoclonal antibodies using a transgenic mouse model. A unique characteristic for the antibodies was the different ways it bound to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the overall reduction in the viral spread for human ACE2.

Widely available HIV testing and treatment services increase life expectancy

Life expectancy among adults living with HIV receiving antiretroviral therapy (ART) in Latin America and the Caribbean has increased significantly since HIV testing and treatment services became more widely available, according to research published today in The Lancet HIV journal.

SARS-CoV-2-associated ssRNAs trigger inflammation and immunity via toll-like receptors

Severe COVID-19 causes sepsis-like manifestations, intense lung injury, and multi-organ failure, all associated with the overproduction of pro-inflammatory cytokines. This "cytokine storm" directly correlates with poor prognosis in this subgroup of patients.

Chronic SARS-CoV-2 infections favor viral adaptation, says study

A new study offers a look at how to keep these hopes alive in the current context of highly infectious variants, which often display immune escape mutations.
