Type of Sugar may Treat Atherosclerosis, mouse study shows

A new study shows that a type of natural sugar called trehalose triggers an important cellular housekeeping process in immune cells that helps treat atherosclerotic plaque. The image shows a cross section of a mouse aorta, the main artery in the body, with a large plaque. Straight red lines toward the upper left are the wall of the aorta. Yellow areas are where housekeeping cells called macrophages are incinerating cellular waste. Credit: Ismail Sergin

Trehalose triggers cellular housekeeping in artery-clogging. Researchers have long sought ways to harness the body’s immune system to treat disease, especially cancer...

Skin has the Nerve to tell you to Scratch

Two skin cells of a mouse show the flow of calcium into the cell in response to a dose of histamine (lower panel). Duke researchers have shown that an ion channel called TRPV4 is the beginning of a chain of messages that ends up signaling "itch" to the brain. Credit: Yong Chen, Duke University

A potential drug target for itching sensations has been developed by researchers. Their work shows that skin cells – when exposed to certain itch-producing chemicals – can powerfully regulate nearby sensory nerve cells and facilitate transmission of the itchy feelings to the brain. The ion channel TRPV4 functions in skin cells as a pivotal switch in this newly revealed signaling pathway. Prof. Wolfgang Liedtke, M.D., Ph...
