NIH-funded study reveals protein, fatty molecules and cellular energy work together during endocytosis Cells ingest proteins and engulf bacteria by a gymnastic, shape-shifting process called endocytosis. Researchers at the National Institutes of Health revealed how a key protein, dynamin, drives the action. Endocytosis lets cells absorb nutrients, import growth factors, prevent infections and accomplish many other vital tasks. Yet, despite decades of research, scientists don't fully...

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. Since pathogens such as HIV can also enter the body´s cells in this way, understanding the underlying molecular mechanisms...

The crystal structure of the dynamin protein – one of the molecular machines that makes cells work – has been revealed, bringing insights into a class of molecules with a wide influence on health and disease. "It's a really cool structure," said Jodi Nunnari, professor and chair of molecular and cellular biology at UC Davis and senior author of the paper, to be published Sept. 18 in the journal Nature. "This is a really important class of molecules for regulating membrane...

New research from the University of California, Davis, and the University of Colorado at Boulder puts an unexpected twist on how mitochondria, the energy-generating structures within cells, divide. The work, which could have implications for a wide range of diseases and conditions, was published today (Sept. 2) in the journal Science. “It´s a paradigm shift in cell biology,” said Jodi Nunnari, professor and chair of molecular cell biology at UC Davis and a co-author of the...

New studies illuminate brain's complex neurotransmission machinery, point to potential source of problems leading to neurodegenerative and psychiatric conditions Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons -- a dance of chemical messages so delicate that missteps often lead to neurological dysfunction. A recent Nature Neuroscience study led by Dr....

The findings may lead to better methods to deliver drugs 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. Cells use these pouches, or vesicles, to carry nutrients and other essential substances, but many medicines also hitch a ride inside them. The structure of the protein, called dynamin, is helping to answer many longstanding questions about...

In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory. Scientists have long believed that other, similar vesicles handle the reverse function, importing life-supporting nutrients and proteins through an independent process. By using a finely honed type of microscopy to more precisely examine these...

Study shows stalled microtubules might be responsible for some cases of the neurological disorder Charcot-Marie-Tooth diseaseStalled microtubules might be responsible for some cases of the neurological disorder Charcot-Marie-Tooth (CMT) disease, Tanabe and Takei report in the June 15, 2009 issue of the Journal of Cell Biology (www.jcb.org). A mutant protein makes the microtubules too stable to perform their jobs, the researchers find.The mutations behind CMT disease slow nerve impulses,...
