Novel virus entry mechanism could lead to new drugs against poxviruses
Research published in the Proceedings of the National Academy of Sciences on 11 April describes how the Imperial College London team discovered the mechanism allowing Vaccinia virus to shed its outer lipid membrane and enter cells. The mechanism is unique in virology and paves the way for development of new antiviral drugs. view more (2006-04-12)
Elastic interactions of membrane proteins
Cellular survival relies crucially on the ability to receive and communicate signals from and to the outside world. A major part of this regulation and communication is performed by proteins within the membrane of a cell. view more (2007-05-04)
Heart attack in a laboratory dish
NWO researchers at Utrecht University have given heart muscle cells a heart attack in the laboratory. This allowed them to observe clearly the change that takes place in the cell membrane during an attack and how the change sometimes leads to the death of the cell. In a healthy cell, one of the components of the membrane, the phospholipids, are... view more... (2001-05-08)
Study shows how disruption of spectrin-actin network causes lens cells in the eye to lose shape
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. view more (2009-09-14)
Budding viral hijackers may co-opt cell machinery for the getaway
When retroviruses, like HIV, infect cells, they take over the cell's machinery to manufacture new copies of themselves. Research published this week in the top-tier open access journal, Journal of Biology, shows that to escape from cells, retroviruses may once again hijack cellular components, in this case molecules normally used to engulf... view more...

Scientists at VTT and the University of Florida take immunotechnology to a new level
Scientists at VTT and the University of Florida take immunotechnology to a new level Mimicking the cell walls transport system by biocoated nanotubes opens novel possibilities for numerous applications Living cells transport selectively molecules in and out through their cell walls. This process is remarkably accurate and efficient. In... view more... (2002-07-04)
HIV-1's 'hijacking mechanism' pinpointed by McGill/JGH researchers
Researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital - along with colleagues at the University of Manitoba and the University of British Columbia - may have found a chink in the armour of the human immunodeficiency virus type 1 (HIV-1), the microorganism which causes... view more...

Rong Li Lab demonstrates the process of mammalian egg maturation
he Rong Li lab team has answered an important question about how mammalian eggs undergo maturation through an intricate process of asymmetric cell division. The team discovered a novel pathway by which chromatin exerts command on the cell membrane to produce a specialized machinery used for cell division. view more (2007-02-06)
Gatekeeping: Penn researchers find new way to open ion channels in cell membranes
Using an enzyme found in the venom of the brown recluse spider, researchers at the University of Pennsylvania School of Medicine have discovered a new way to open molecular pores, called ion channels, in the membrane of cells. view more (2006-07-18)
Feeling up Cells
Locally resolved detection of cell signals with microelectrodes No matter how small, a living cell does not have a uniform structure. Instead, it has „organs“, called organelles, which are assigned various tasks. Even the „shell“ of the cell, its membrane, is not uniform. Functional building blocks, such as ion channels,... view more... (2001-03-01)
Methane bacteria possess pressure valve
Microbiologists from the University of Nijmegen have discovered that a methane-forming archaeabacterium sometimes deliberately allows hydrogen ions to leak out of its cell. At high hydrogen concentrations in particular, the cell membrane works as a sort of pressure valve. The waste of energy seems to be of vital importance for the microorganism.... view more...

Prions link cholesterol to neurodegeneration
Prion infection of neurons increases the free cholesterol content in cell membranes. A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for cholesterol in other neurodegenerative diseases. view more (2008-02-12)
Findings could improve fuel cell efficiency
A new type of membrane based on tiny iron particles appears to address one of the major limitations exhibited by current power-generating fuel cell technology. view more (2008-03-20)
Targeted drug delivery now possible with 'pHLIP' peptide
Scientists at Yale and the University of Rhode Island report the development of a peptide that can specifically and directly deliver molecules to the inside of cells like a nanosyringe, creating a new tool for drug delivery, gene control and imaging of diseased tissues. view more (2006-04-12)
Groundbreaking Discovery May Lead to Stronger Antibiotics
The last decade has seen a dramatic decline in the effectiveness of antibiotics, resulting in a mounting public health crisis across the world. A new breakthrough by University of Virginia researchers provides physicians and patients a potential new approach toward the creation of less resistant and more effective antibiotics. view more (2008-10-02)
New 'control knobs' for stem cells identified
Natural changes in voltage that occur across the membrane of adult human stem cells are a powerful controlling factor in the process by which these stem cells differentiate, according to research published by Tufts University scientists. view more (2008-12-04)
Jefferson scientists uncover new clues to how crucial molecular gatekeepers work
One of the biggest mysteries in molecular biology is exactly how ion channels - tiny protein pores through which molecules such as calcium and potassium flow in and out of cells - operate. view more (2005-10-12)
Molecular motors may speed nutrient processing
Matthew Tyska, Ph.D., recalls being intrigued, from the first day of his postdoctoral fellowship in 1999, with a nearly 30-year-old photograph. It was an electron micrograph that showed the internal structures of an intestinal cell microvillus, a finger-like protrusion on the cell surface. Microvilli are common features on the epithelial cells... view more... (2007-05-31)
How mitochondria get their membranes bent
Mitochondria are the powerhouses of cells. Underneath their smooth surface they harbor an elaborately folded inner membrane. It holds a multitude of bottleneck like invaginations, which expand into elongated cavities (cristae). view more (2009-06-25)
Researchers solve mystery of how nuclear pores duplicate before cell division
Researchers have long wondered how nuclear pores - the all-important channels that control the flow of information in and out of a cell's nucleus - double in number to prepare for the split to come when a cell divides. view more (2006-04-21)
