Glioblastoma, the most common and deadly form of brain cancer, grows rapidly to invade and destroy healthy brain tissue. The tumor sends out cancerous tendrils into the brain that make surgical tumor removal extremely difficult or impossible. Now, scientists have found the immunotherapy treatment anti-CTLA-4 leads to considerably greater survival of mice with glioblastoma. Furthermore, […]
E-cigarettes and marijuana have similar harmful effects on the heart as tobacco cigarettes, opening the door to abnormal heart rhythms, reports a team of researchers at UC San Francisco. “We found that cigarettes, e-cigarettes, and marijuana greatly interfere with the electrical activity, structure, and neural regulation of the heart,” said lead author Huiliang Qiu, MD, […]

Nanovesicles can be bioengineered to target cancer cells and deliver treatments directly, according to research at Binghamton University, State University of New York. Two unfortunate facts about chemotherapy: It can harm healthy cells as well as cancerous ones, and many therapeutic targets stay within cancer cells, making them harder to reach. Binghamton University biomedical engineers […]
Atherosclerosis is a disease in which fat, cholesterol, and other substances build up inside artery walls. This can lead to plaque formation, which can block arteries and cause heart attacks and strokes. Immune cells play a key role in cleaning the blood, by interacting with red blood cell extracellular vesicles (RBCEVs), which are nano-sized particles […]
