Immune cells promote or prevent cytomegalovirus activity in mice depending on location in the body

New findings could inform development of treatments that manipulate immune cell activity Immune system cells called regulatory T cells appear to promote cytomegalovirus (CMV) latency in the spleen of mice, but suppress it in the salivary gland. Maha Almanan of the University of Cincinnati College of Medicine, Cincinnati Children’s Hospital Research Foundation, and colleagues present [...]

Spider peptides battle superbugs and cancer

As antibiotic resistance rises and fears over superbugs grow, scientists are looking for new treatment options. One area of focus is antimicrobial peptides (AMPs), which could someday be an alternative to currently prescribed antibiotics, many of which are becoming increasingly useless against some bacteria. Now, a team reports in ACS Chemical Biology that they have [...]

A personalized approach to Alzheimer’s disease prevention

Alzheimer’s disease (AD) is a type of dementia that causes problems with memory, thinking, and behavior. It affects more than 5 million Americans. The Alzheimer’s Association estimates that some 16 million people will develop the disease by the year 2050 if an effective treatment is not discovered. Symptoms of AD usually develop slowly and worsen [...]

Scientists reveal source of human heartbeat in 3D

A pioneering new study is set to help surgeons repair hearts without damaging precious tissue. A team of scientists from Liverpool John Moores University (LJMU), The University of Manchester, Aarhus University and Newcastle University, have developed a way of producing 3D data to show the cardiac conduction system – the special cells that enable our [...]

Study identifies essential genes for cancer immunotherapy

A new study identifies genes that are necessary in cancer cells for immunotherapy to work, addressing the problem of why some tumors don’t respond to immunotherapy or respond initially but then stop as tumor cells develop resistance to immunotherapy. The study, from the National Cancer Institute (NCI), was led by Nicholas Restifo, M.D., a senior [...]
