(Medical Xpress)—A group of researchers in Austria and Switzerland has for the first time proven that immune cells migrate along chemical concentration gradients. This process has long been assumed but never demonstrated ...
Neurons in the cerebral cortex, a region in the mammalian brain involved in complex motor functions, sensory perception and cognition, can have very different qualities and characteristics. These neurons are known to be formed ...
Increasingly dense cell clusters in growing tumors convert blood vessels into fiber-filled channels. This makes immune cells less effective, as findings by researchers from ETH Zurich and the University of Strasbourg suggest. ...
