... the NK cells, robbing them of the ability to help stimulate vessel remodeling. This is a seemingly unusual role for NK cells, whose traditional job in the circulation is to recognize and destroy infected cells and tumor cells. "We don't really know what the NK cells are doing", the authors point out. These ...Estrogen protects male rats from aortic aneurysms
...male. After the rats were treated with elastase to stimulate aneurysm formation, scientists compared the effects on the transplanted aortas. All male aortas transplanted into male rats developed an aneurysm, while only 17 percent of female aortas transplanted into female rats did so. But when female aortas wer...Channel protein converts vibrations to electrical signal
...ure the electrical response that it gives when you stimulate the cell," Corey said. By putting a microelectrode on the mouse hair cells, the scientists could directly measure the amount of current flowing through the channels. With lower levels of TRPA1, current flow was diminished. In zebrafish embryos, they ......idepressants. FGFs are a family of molecules that stimulate cell growth in many areas of the body, and are involved in the growth of multiple tissues and in growth that takes place at various stages of life. They have potent effects during embryonic, fetal and child development, and can modify the size and st...Scientists identify new cause of obesity
...rves. If fat stores are increasing, theses signals stimulate MC4R, triggering physiological responses that decrease appetite. If fat reserves are decreasing, these signals turn off, deactivating MC4R and increasing appetite.
