Latest Cell membrane Stories
Trying to understand the complex workings of a biological cell by teasing out the function of every molecule within it is a daunting task.
Just as people plug in to computers, smart phones and electric outlets to communicate, electric fish communicate by quickly plugging special channels into their cells to generate electrical impulses.
New data on signaling proteins, called G proteins, may prove important in fighting diseases such as cardiovascular, neurodegenerative disorders, and cancer.
University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium.
A network of proteins underlying the plasma membrane keeps epithelial cells in shape and maintains their orderly hexagonal packing in the mouse lens, say Nowak et al. The study will appear in the September 21, 2009 issue of the Journal of Cell Biology (online September 14).
Reveals shape-shifting atomic interactions; suggests mechanism and possible drug targets.
As part of the intricate ballet of synaptic transmission from one neuron to the next, tiny vesicles â€“ bubbles containing the chemical neurotransmitters that make information exchange possibleâ€”travel to the tip of neurons (synapses), where they fuse with the cell's membrane (a process called exocytosis).
Researchers in the United States and Spain have discovered that a tool widely used in nanoscale imaging works differently in watery environments, a step toward better using the instrument to study biological molecules and structures.
Yale University researchers have discovered how a protein within most cell membranes helps maintain normal cell size, a breakthrough in basic biology that has implications for a variety of diseases such as sickle cell anemia and disorders of the nervous system.
Recycling is a critical component in the process of transmitting information from one neuron to the next, and a large protein called Tweek plays a critical role, said an international consortium of researchers led by Baylor College of Medicine (www.bcm.edu) in a report in the current issue of the journal Neuron.
