Study: Structural defect in skin cells can contribute to allergy development

In a new study published in Nature Genetics, Northwestern Medicine and Tel Aviv University scientists have found that a structural defect in skin cells can contribute to allergy development, including skin and food allergies, traditionally thought primarily to be a dysfunction of the immune system.

Exo70 protein responsible for plasma membrane reshaping and cell movement

Both basic scientists and clinicians have an interest in how the cells of our body move. Cells must be mobile in order for organisms to grow, to heal, to transmit information internally, to mount immune responses and to conduct a host of other activities necessary for survival.

Specialized endocytocis play a crucial role in shaping cells themselves

The process cells use to 'swallow' up nutrients, hormones and other signals from their environment - called endocytosis - can play a crucial role in shaping the cells themselves, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have found.

ASU expert receives $1.6 million grant to advance microscopy imaging research

At Arizona State University's Biodesign Institute, Nongjian (NJ) Tao has been designing advanced microscopy methods with the ambitious aim of capturing molecular-scale phenomena in living systems. The new techniques, which combine multiple imaging modalities, are poised to revolutionize the study of biology and the development of new drugs.

Wiring diagram of retinal neurons: The first step toward mapping the human brain

The human brain has 100 billion neurons, connected to each other in networks that allow us to interpret the world around us, plan for the future, and control our actions and movements. MIT neuroscientist Sebastian Seung wants to map those networks, creating a wiring diagram of the brain that could help scientists learn how we each become our unique selves.

NIH-funded study of aquaporin proteins could hold clues to cataract

Researchers have achieved dynamic, atomic-scale views of a protein needed to maintain the transparency of the lens in the human eye. The work, funded in part by the National Institutes of Health, could lead to new insights and drugs for treating cataract and a variety of other health conditions.

Scientists solve structure of infection tool used by Yersinia bacterium

Abdominal pain, fever, diarrhoea -- these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called injectisome.

Scientists discover new details of biochemical interactions necessary for cell division

Building on earlier work exploring the complex choreography by which intricate cellular proteins interact with and copy DNA prior to cell division, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators have captured a key step-molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target.

Research: Experimental drug can protect kidneys from acute kidney injury

New research reveals the mechanism by which an experimental drug can protect the kidneys from sudden damage, called acute kidney injury (AKI). The findings, which appear in an upcoming issue of the Journal of the American Society of Nephrology (JASN), show how the drug may be able to save many lives and cut medical costs related to the condition.

Researchers determine precise chemical structure of HIV capsid

Researchers have determined the precise chemical structure of the HIV capsid, a protein shell that protects the virus's genetic material and is a key to its ability to infect and debilitate the human body's defense mechanism.

Scientists move closer to understanding HIV-1 infection

Scientists have long been unable to fully explain how infections attack the body, but now a team of researchers, including one from the University of Central Florida, has taken a step closer to understanding how the process works in HIV-1. The results mean that one day that knowledge may prevent infection.

New research reveals how endothelium maintains highly efficient barrier function

The endothelium, the cellular layer lining the body's blood vessels, is extremely resilient. Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body's circulatory system.

Metallurgists use microwave oven to produce nanocrystal semiconductors

University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity.

Scientists develop new technique for imaging nanoparticle dynamics with atomic resolution

The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects.

Dr. Stefano Vanin investigates the Fardos mummies of pre-Columbian Peru

The mummified bodies of Peruvians who died up to 1,000 years ago will yield up their secrets, thanks to a prestigious research project by the University of Huddersfield's Dr Stefano Vanin and two of his students in collaboration with the University of Pisa and the Ancient World Society.

Researchers create complete visual map of telomerase enzyme

Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.
