Latest Vesicle Stories
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.
Every cell lining the small intestine bristles with thousands of tightly packed microvilli that project into the gut lumen, forming a brush border that absorbs nutrients and protects the body from intestinal bacteria.
Two new construction manuals are now available for the world's smallest lamps.
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.
The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside.
Similar architecture of an essential nuclear pore complex module and cellâ€™s vesicle coats supports common evolutionary origin.
A single crafty protein allows the deadly bacterium Salmonella enterica to both invade cells lining the intestine and hijack cellular functions to avoid destruction, Yale researchers report in the April 17 issue of the journal Cell.
By Dinh, Anh-Tuan Pangarkar, Chinmay; Mitragotri, Samir Unlike macroscopic problems in mass, energy and momentum transfer, which are described by continuum equations, the movements and interactions of the nanoscale entities within a cell constitute a transport phenomenon known as discrete nanoscale transport (DNT).
By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria pathogen destroys the cells in which it resides. The work is reported in Current Biology by Joshua Zimmerberg and colleagues at the U.S. National Institutes of Health.
Scientists have used chemical genomics to identify novel compounds that affect the ability of plants to alter their direction of growth in response to gravity, a phenomenon known as gravitropism. Combined with a plant's formidable genetic map, chemical genomics is becoming a powerful new tool in plant biology.
Phallusia nigra is a species of sea squirt (tunicate) found in tropical seas around the world. It is usually found in shallow waters attached to any hard substrate. It is a solitary animal rather than living in colonies. Although the native range of this animal is unknown, the tropical western Atlantic Ocean, the Red Sea and the Indian Ocean are possibilities. Like all ascidians, this species has a thick leathery envelope (tunic) containing cellulosic material. The tunic encloses a...
