Researchers explore molecular level changes when body recognizes, defends against pathogens

Researchers at Johns Hopkins have zoomed in on what is going on at the molecular level when the body recognizes and defends against an attack of pathogens, and the findings, they say, could influence how drugs are developed to treat autoimmune diseases.

Study quantifies photoactivation efficiency of fluorescent proteins

To know how many proteins assemble together at the nanoscale is fundamental for understanding protein function. Sometimes, proteins must be in an "oligomeric" state to be functional, although "oligomerization" of certain proteins can also lead to diseases. The ability to determine protein stoichiometry and monitor changes in the balance between monomeric, dimeric and multi-meric proteins can allow scientists to see the differences between a properly functioning cell and a diseased cell. Therefore, there is a great interest in being able to count proteins and determine their stoichiometry.

Researcher reveals how temperature impacts development of embryos

In nature, animals face a broad range of temperatures, and at times the heat can become taxing. When it becomes too hot to survive, some animals can simply migrate to more favorable climates, but what if you are a mere embryo confined within an egg and cannot escape the heat?

Uneven distribution of cellular organelles during cell division may enhance bacterial population's survival

Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways.

Study reveals potential links to the underlying causes of cancers

New research by scientists at the University of Exeter has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide - a finding with potential links to the underlying causes of many cancers.

New technique could help researchers unlock the secrets of respiratory syncytial virus

By the time they're two, most children have had respiratory syncytial virus and suffered symptoms no worse than a bad cold. But for some children, especially premature babies and those with underlying health conditions, RSV can lead to pneumonia and bronchitis - which can require hospitalization and have long-term consequences.

Transplanting self-donated Schwann cells aids hind limb functional recovery

A study carried out at the University of Miami Miller School of Medicine for "The Miami Project to Cure Paralysis" has found that transplanting self-donated Schwann cells (SCs, the principal ensheathing cells of the nervous system) that are elongated so as to bridge scar tissue in the injured spinal cord, aids hind limb functional recovery in rats modeled with spinal cord injury.

Innovation leads to faster drug therapies, increased understanding of proteins on microscopic level

Membrane proteins are the "gatekeepers" that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of "force microscopes" that are available to researchers and the one-dimensional results these microscopes reveal.

New Opterra multipoint scanning confocal microscope from Bruker

Today at the 2013 American Society for Cell Biology Annual Meeting, Bruker introduced the Opterra Multipoint Scanning Confocal Microscope, which sets a new standard for integration of confocal imaging with photoactivation.

Researchers gather first direct evidence of how microbubbles cause blood clot's demise

Ultrasound-stimulated microbubbles have been showing promise in recent years as a non-invasive way to break up dangerous blood clots. But though many researchers have studied the effectiveness of this technique, not much was understood about why it works. Now a team of researchers in Toronto has collected the first direct evidence showing how these wiggling microbubbles cause a blood clot's demise. The team's findings are featured in the AIP Publishing journal Applied Physics Letters.

Transport of bacterial substrates through injectisome observed almost in real time

When attacking body cells, bacteria, such as salmonellae or Yersinia (plague pathogens), inject specific bacterial proteins through hollow, syringe-like structures - called injectisomes - into the host cells. These substances reprogram the cells and can thus overcome their defense. From then on, they can infiltrate the cells unhindered in large numbers, and trigger diseases such as typhus, plague, or cholera.

Moberg announces positive results from phase ll study of MOB-015 for treatment of nail fungus

Moberg Pharma AB today announced positive interim results from its ongoing phase ll study of MOB-015. After six months of treatment with MOB-015, 40 per cent of the patients were mycologically cured and no safety concerns were identified.

New research offers fresh insights to drug designers searching for better pain treatments

In a technical tour de force, UC San Francisco scientists have determined, at near-atomic resolution, the structure of a protein that plays a central role in the perception of pain and heat.

Researchers examine how spindle apparatus self-organizes

Researchers at Waseda University in Japan have identified key information to help explain the formation of the "spindle apparatus", a structure required for cell division. Their findings shed light on the mechanisms behind "self-organization" - an essential characteristic of biological structures.

Study brings effective hepatitis C cure closer to reality

Scientists at The Scripps Research Institute have determined the most detailed picture yet of a crucial part of the hepatitis C virus, which the virus uses to infect liver cells. The new data reveal unexpected structural features of this protein and should greatly speed efforts to make an effective hepatitis C vaccine.

Seed grants support cancer diagnosis and treatment, vascular health research

Five teams of scientists earned research seed grants awarded this year by the John S. Dunn Foundation. The awards support new collaborations by researchers at Rice University's BioScience Research Collaborative (BRC) and their partners at other institutional members of the Gulf Coast Consortia (GCC).

Researchers identify key immune cells that turn body's defenders against invading golden staph

When golden staph enters our skin it can identify the key immune cells and 'nuke' our body's immune response.

Waseda University researchers observe molecular motors that play critical role in chromosome transport

Researchers at Waseda University in Japan have for the first time directly observed the “molecular motor”, called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. Their findings are expected to contribute greatly to elucidating the molecular mechanisms of chromosome segregation, a key aspect of the development of certain medical disorders including cancer and birth defects.

Scientists use RNAi technology to reveal genes responsible for treating Parkinson's disease

Scientists at the National Institutes of Health have used RNA interference (RNAi) technology to reveal dozens of genes which may represent new therapeutic targets for treating Parkinson's disease. The findings also may be relevant to several diseases caused by damage to mitochondria, the biological power plants found in cells throughout the body.
