Cancer cells disarm cellular attackers by extending out nanoscale tentacles

To grow and spread, cancer cells must evade the immune system. Investigators from Brigham and Women's Hospital and MIT used the power of nanotechnology to discover a new way that cancer can disarm its would-be cellular attackers by extending out nanoscale tentacles that can reach into an immune cell and pull out its powerpack.

Study reveals mechanism by which vitamin D reduces inflammation caused by immune cells

Scientists recently gained insights into how vitamin D functions to reduce inflammation caused by immune cells that might be relevant to the responses during severe COVID-19. In a study jointly published by Purdue University and the National Institutes of Health, scientists do just that.

New test enables patient-specific monitoring and treatment for ovarian cancer

Around 870 cases of ovarian cancer are reported in Belgium every year. Most of these patients are treated with surgical interventions and/or chemotherapy.

New trial demonstrates stable coagulation factor VIII in hemophilia A patients after gene therapy

A novel gene therapy for hemophilia A led to sustained expression of the clotting factor those patients lack, resulting in a reduction – or in some cases complete elimination – of painful and potentially life-threatening bleeding events, according to a new study led by researchers at Children's Hospital of Philadelphia.

Researchers provide a clearer picture of healthy development of the lungs

Researchers have compiled the most comprehensive road map of the protein composition of human lungs, providing a clearer picture of the healthy development of this essential organ that made terrestrial life possible.

Researchers receive $22 million grant for clinical trial that aims to reduce lung transplant rejection

Physicians at Washington University School of Medicine in St. Louis and Massachusetts General Hospital/Harvard Medical School in Boston have received a seven-year, $22 million grant from the National Institute of Allergy and Infectious Diseases of the National Institutes of Health to help lead a multicenter clinical trial evaluating whether a novel immunosuppressant can reduce the risk of organ rejection after a lung transplant.

Study reveals complex interplay between diet, gut microbiota, and immune function

The cliché "you are what you eat" has been used for hundreds of years to illustrate the link between diet and health. Now, an international team of researchers has found the molecular proof of this concept, demonstrating how diet ultimately affects immunity through the gut microbiome.

Lung autopsies provide a clearer picture of how SARS-CoV-2 virus spreads and causes damage

Lung autopsy and plasma samples from people who died of COVID-19 have provided a clearer picture of how the SARS-CoV-2 virus spreads and damages lung tissue.

Researchers identify new group of antibacterial molecules

Researchers at Karolinska Institutet, Umeå University, and the University of Bonn have identified a new group of molecules that have an antibacterial effect against many antibiotic-resistant bacteria.

Phantosmia, parosmia, and dysgeusia in COVID-19 patients

A team of researchers investigated qualitative aspects of olfactory and gustatory symptoms such as phantosmia, parosmia, and dysgeusia and their possible co-relation with the adaptive immune system.

Young adults with cancer may require different treatments than older patients

Not all tumors are alike. Young adults who are diagnosed with skin, colon, and other cancer types may require different treatments than older patients receive.

Scientists identify new gene that contributes to type 1 diabetes progression

When the pro-inflammatory pair, a receptor called CCR2 and its ligand CCL-2, get together, it increases the risk of developing type 1 diabetes, scientists report.

Study: Covid-19 vaccine-elicited immune cells persist six months after vaccination

A recent study by Johns Hopkins Medicine researchers provides evidence that CD4+ T lymphocytes — immune system cells also known as helper T cells — produced by people who received either of the two available messenger RNA (mRNA) vaccines for COVID-19 persist six months after vaccination at only slightly reduced levels from two weeks after vaccination and are at significantly higher levels than for those who are unvaccinated.

Study analyzes association between obesity and endothelial dysfunction in COVID-19 patients

In COVID-19 patients, obesity is the factor most associated with the development of endothelial dysfunction, a condition in which the blood vessels become unable to contract and relax adequately, increasing the risk of events such as heart attacks, thrombosis (blood clotting), and stroke.

Scientists develop a promising new approach to potentially treat Alzheimer's disease

A promising new approach to potentially treat Alzheimer's disease – and also vaccinate against it – has been developed by a team of UK and German scientists.

Inflammatory chemicals involved in fat metabolism play key role in ALS, study shows

A new study using genetically engineered mice and human cell and tissue samples has added to evidence that higher levels of inflammatory chemicals involved in fat metabolism occur in people with amyotrophic lateral sclerosis (ALS), the neuromuscular disorder, also known as Lou Gehrig's disease.
