Watching Actin in Action: Unveiling new discoveries about our cytoskeleton

Just like complex vertebrates, cells are sup­ported by their own kind of skeleton. In fact, the cell’s skeleton, called the cytoskeleton, is very dynamic—the constituent “bones” can assemble and disassemble as required. One key player in the cytoskeleton is the

MVP CAR T-Cells: How a new technology can predict clinical responses to targeted T-cell cancer therapy

Everyone generates cancerous cells. The human body is made up of more than a hundred million cells that may mutate during the process of division to grow uncontrollably—i.e. become cancerous. However, the human immune system has built-in mechanisms that detect
