Latest Cytosis Stories
Cells ingest proteins and engulf bacteria by a gymnastic, shape-shifting process called endocytosis.
Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have combined the power of two kinds of microscope to produce a 3-dimensional movie of how cells ‘swallow’ nutrients and other molecules by engulfing them.
Dr. Katja Fälber and Professor Oliver Daumke, structural biologists at the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, together with researchers from Freie Universität (FU) Berlin, have determined the molecular structure of dynamin, a ‘wire-puller’ that mediates nutrient uptake into the cell.
Just as we must take out the trash to keep our homes clean and safe, it is essential that our cells have mechanisms for dealing with wastes and worn-out proteins.
A team of scientists at The Scripps Research Institute and the National Institutes of Health (NIH) has discovered the structure of a protein that pinches off tiny pouches from cells' outer membranes.
Max Planck scientists develop new strategy to play major role in research on human diseases.
The transmission of information from one neuron to the next is an unseen intricate ballet.
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).
Success in soccer sometimes comes with "bending it like Beckham." Success in cellular fusion â€” as occurs at the moment of conception and when nerve cells exchange neurotransmitters â€” requires that a membrane be bent before the merging process can begin, University of Wisconsin-Madison researchers have shown.
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.
