Protein that provides innate defense against HIV could lead to new treatments
By identifying a protein that restricts the release of HIV-1 virus from human cells, scientists believe they may be closer to identifying new approaches to treatment. The research is published in the advance online edition of Nature Medicine. view more (2008-05-27)
£11.5m for new structural proteomics research programmes
BBSRC has announced two new research programmes that together will receive £11.5m under the Structural Proteomics of Rational Targets Initiative (SPoRT). The Membrane Protein Structure Initiative (MPSI), a consortium of experienced membrane research groups at universities and institutes across the UK and led by the University of Glasgow,... view more...

UCF professor finds new way deadly food-borne bacteria spread
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. view more (2009-09-21)
Visualizing virus replication in 3 dimensions
Dengue fever is the most common infectious disease transmitted by mosquitoes - some 100 million people around the world are infected. Researchers at the Hygiene Institute at Heidelberg University Hospital were the first to present a three-dimensional model of the location in the human cell where the virus is reproduced. view more (2009-05-08)
Crystal structure enables tailoring of pharmaceuticals against asthma
Researchers at Karolinska Institutet in Sweden have managed to elucidate the crystal structure of a human membrane protein - LTC4 synthase - which has a major influence on the development of asthma. view more (2007-07-17)
Nanoresearchers challenge dogma in protein transportation in cells
New data on signalling proteins, called G proteins, may prove important in fighting diseases such as cardiovascular, neurodegenerative disorders, and cancer. view more (2009-09-22)
Saving Cells - Safer Method for Filtering Sensitive Biological Products
For many years, engineers have worked to efficiently filter valuable bio-process products on an industrial economic scale. The challenge has been to push rates up without incurring high shear rates and resultant cell lysis, which would cause loss of yield. High shear can destroy delicate and valuable biological materials such as proteins, blood,... view more... (2004-07-23)
Lamin A/C deficiency is 'unnerving'
Mutations in the nuclear intermediate filament lamin A/C (LMNA) gene are associated with Emery-Dreifuss muscular dystrophy, but cause the disease by unknown mechanisms. Méjat et al. show that one mechanism involves the disruption of neuromuscular junctions. view more (2009-01-05)
NIST membrane model may unlock secrets of early-stage Alzheimer's
Researchers at the National Institute of Standards and Technology (NIST) and three collaborating institutions are using a new laboratory model of the membrane surrounding neurons in the brain to study how a protein long suspected of a role in early-stage Alzheimer's disease actually impairs a neuron's structure and function. view more (2008-07-24)
A balancing act between the sexes
Recent research at the European Molecular Biology Laboratory (EMBL) reveals new insights into how cells achieve equality between the sexes. view more (2006-03-17)
Semiconductor membrane mimics biological behavior of ion channels
A semiconductor membrane designed by researchers at the University of Illinois could offer more flexibility and better electrical performance than biological membranes. view more (2007-07-13)
Artificial membranes can reveal biological weapons
Today there is a great need for portable equipment that can quickly detect chemical and biological weapons such as nerve gases, viruses, bacteria, and toxins. In a new dissertation the Swedish researcher Inga Gustafsson shows that artificial membranes can be used for this purpose in future biosensors. Biosensors have already... view more... (2004-01-16)
Researchers reveal HIV peptide's possible pathway into the cell
Two theoretical physicists at Rensselaer Polytechnic Institute have uncovered what they believe is the long-sought-after pathway that an HIV peptide takes to enter healthy cells. The theorists analyzed two years of biocomputation and simulation to uncover a surprisingly simple mechanism describing how this protein fragment penetrates the cell... view more... (2008-01-18)
Researchers discover how compounds prevent viruses from entering cells
Compounds called defensins-known to prevent viruses from entering cells-appear to do so by preventing the virus from merging to cells' outer membrane. view more (2005-09-16)
Membrane complexes take flight
Against currently held dogma, scientists at the Universities of Cambridge and Bristol have revealed that the interactions within membrane complexes can be maintained intact in the vacuum of a mass spectrometer. Their research is published in this week's edition of Science Express. view more (2008-06-13)
Some like it hot! Structure of receptor for hot chili pepper and pain revealed
You can now not only feel the spicy kick of a jalapeno pepper, you can also see it in full 3D, thanks to researchers at Baylor College of Medicine in Houston. view more (2008-05-20)
ESRF lightsource helps tailoring new treatments against asthma
Researchers from Sweden and France have deciphered the crystal structure of a human membrane protein which has a major influence on the development of asthma. view more (2007-08-03)
Metastatic movements in 3-D
Caswell et al.report in the Journal of Cell Biology how the altered behavior of integrins can prompt metastatic movement in tumor cells. view more (2008-10-06)
Simple membranes could have allowed nutrients to pass into primitive cells
When the first cells developed, how could they bring molecules from the environment into their living interior without the specialized structures found on the modern cell membrane? view more (2008-06-05)
Intestinal cells surprisingly active in pursuit of nutrition and defense
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. view more (2009-06-29)
