In a study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signals from cell to cell ...
Membrane proteins are proteins found in cell membranes, either at the surface or on intracellular organelles. Integral membrane proteins such as receptors and ion channels span the membrane.
Biology textbooks may need a revision, say Johns Hopkins Medicine scientists, who present new evidence that an armlike structure of mammalian brain cells may be a different shape than scientists have ...
