‘Browning’ white fat cells opens new avenue to obesity prevention

Scientists are getting closer to understanding how to turn the body’s energy-storing white fat cells into energy-burning beige fat cells, opening up hopes that fat deposits could one day be deliberately manipulated to prevent obesity and related health conditions. Professor

Study: Fat cells play key role in dangerous transformation of melanoma

Researchers at Tel Aviv University, led by Prof. Carmit Levy and Dr. Tamar Golan of the Department of Human Genetics and Biochemistry at TAU’s Sackler School of Medicine, have discovered that fat cells are involved in the transformation that melanoma

Fingerprint of multiple sclerosis immune cells identified

Researchers at the University of Zurich have identified a cell population that likely plays a key role in multiple sclerosis (MS). T helper cells in the blood of MS patients infiltrate the central nervous system, where they can cause inflammation

MicroRNAs from human fat cells can impair macrophage ability to eliminate cholesterol

A multi-institutional team led by research faculty at Children’s National in Washington, D.C., finds that extracellular vesicles (EVs) derived from kids’ fat can play a pivotal role in ratcheting up risk for atherosclerotic cardiovascular disease well before any worrisome symptoms

Overstuffed cancer cells may have an Achilles’ heel

In a study using yeast cells and data from cancer cell lines, Johns Hopkins University scientists report they have found a potential weak spot among cancer cells that have extra sets of chromosomes, the structures that carry genetic material. The

Low doses of radiation promote cancer-capable cells

Low doses of radiation equivalent to three CT scans, which are considered safe, give cancer-capable cells a competitive advantage over normal cells in healthy tissue, scientists have discovered. Researchers at the Wellcome Sanger Institute and the University of Cambridge studied

Making cancer stem cells visible to the immune system

Leukemia stem cells protect themselves against the immune defense by suppressing a target molecule for killer cells. This protective mechanism can be tricked with drugs. In the journal Nature, scientists from Basel, Tübingen and Heidelberg describe the new therapeutic approaches

HIV-infected cells persist in CSF in individuals on long-term ART

(HealthDay)—About half of HIV-positive individuals on long-term antiretroviral therapy (ART) have HIV-infected cells in their cerebrospinal fluid (CSF), according to a study published online July 15 in the Journal of Clinical Investigation. Serena Spudich, M.D., from Yale University in New

A genomic barcode tracker for immune cells

Researchers from the Garvan Institute of Medical Research have developed a new method to spot rare immune cells that are reactive against cancer cells, from within a patient’s own immune system. The patented ‘RAGE-seq’ method enables scientists to track how

Can magnetic stem cells improve cartilage repair?

Cells equipped with superparamagnetic iron oxide nanoparticles (SPIOs) can be directed to a specific location by an external magnetic field, which is beneficial for tissue repair. Researchers have now taken the important step of evaluating the safety and efficacy of

HIV: Reprogramming cells to control infection

Cells from the rare individuals who naturally control HIV infection have been the focus of investigation for nearly 15 years with the aim of elucidating their specific features. Following research on the ANRS CO21 CODEX and CO6 PRIMO cohorts, scientists

Same excitotoxin that damages brain cells is also being deliberately added to vaccines, reveals CDC document

A staple in food seasonings used make recipes more flavorful, monosodium glutamate (MSG), hides a toxicity that is often overlooked due to its apparent usefulness in the kitchen. MSG was initially thought to be safe, as it is a naturally

Aster herb found to inhibit growth of cancer cells

If there’s one thing almost everyone is afraid of, it’s cancer. This disease is a major cause of concern since it remains to be one of the biggest and deadliest health problems in the world, causing an estimated 9.6 million deaths in 2018
