Macrophages, a type of white blood cell that can destroy invading pathogens, have an innate ability to infiltrate tumor cells, making them a potentially important tool in treatments that use transplanted cells to fight disease, known as cell therapy. In the lab, macrophages show a lot of promise in treating cancer but so far, clinical trials have been a disappointment and biologists are trying to figure out why.

The mental health of people comes at a cost when they take on unpaid caring roles for friends and family. That’s according to research from St George’s, University of London and UCL which is published today in The Lancet Public Health.

Globally speaking, most HIV infections in young women occur in poorer countries, where up to 25% of women may be infected with the HIV virus. For heterosexual women, prevention through the use of Pre-Exposure Prophylaxis (PrEP) and its active ingredients, emtricitabine/tenofovir, represents one of the few options available to protect themselves from HIV infection. Additionally, it is a very inexpensive drug, available in most resource-constrained countries.

Neuropsychiatric symptoms of long COVID, including brain fog, inability to concentrate, and headache, have puzzled researchers and clinicians, who are hunting for those symptoms’ causes. A new study found that neuroinflammation and blood-brain-barrier dysfunction are not likely drivers of the symptoms, giving researchers more clues in their quest to uncover what actually may be the culprit.

A national study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) demonstrates that neighborhood exposure to environmental hazards is significantly associated with poor cardiovascular health across the United States.

A group of international scientists say they have encountered many hurdles in accessing information for a study to examine clinical trial data used to support FDA-approved anticancer medicines even when the data was classified as eligible for access and transparent sharing.

A research collaboration has developed a technology capable of extracting mesenchymal stem cells (MSCs) directly from pure bone marrow—also known as bone marrow aspirate (BMA), a pivotal source of MSCs—without dilution.
