Researchers add crucial information on how the body's T cells react to parasitic diseases

...in kinds of diseases, one area has remained murky: disorders caused by protozoan parasites. Now, because of a study just published and led by scientists at the University of Georgia, researchers are closer than ever to understanding how T cells respond to parasitic diseases that kill millions each year. "We ...

Studies suggest new brain protein may help in treating schizophrenia, insomnia and anxiety

...S and its receptor might be associated with mental disorders and developing animal models that lack parts of the NPS system in order to better understand its functions. ...

Production of key Alzheimer's protein monitored for first time in humans

Study finds how organs monitor themselves during early development

...erful feedback loop could help treat many kinds of disorders and show how the power of stem cells could be harnessed to help organs call different cell types into action and regenerate, the researchers said. Stem cells are cells that have not yet specialized and can develop into any number of different cell ty...

Ritalin packs punch by elevating norepinephrine, suppressing nerve signal transmissions

...ds people with attention deficit and hyperactivity disorders to improve their focus without increasing their motor activity. Methylphenidate, prescribed under the brand name Ritalin, has been used for more than 20 years, mostly in children, to treat attention deficit hyperactivity disorder (ADHD) and attention...

'Prosthetic' retinal cells let blind mice see light

... that resembles the defect in such inherited human disorders as retinitis pigmentosa. Unlike the retinal rods and cones that normally function as light-sensing cells in the eye, these retinal neurons are normally not photosensitive. The light-sensitive protein they used, called channelrhodopsin-2 (ChR2), is fo...

Man-made heart tissue improves cardiac performance

...ed in the journal Artificial Organs. With heart disorders affecting individuals globally and contributing to increasing mortality rates, there has been a need to develop new treatment options. One of the specific challenges in the field of tissue engineering is to produce blood vessels within heart muscle ...

Study finds 60 new genes controlled by DNA snippet

...ntial to create new classes of treatment for nerve disorders and heart failure. Such sequences may also help to explain why humans are so complex, despite having one-fifth as much genetic material as wheat for instance. Medical center researchers are working on just one of more than 100 regulatory sequences id...

A large step forward in the fight against African sleeping sickness

...eeping sickness. The disease produces severe sleep disorders that ultimately end in coma, followed by death. At present, fewer than 10% of the patients are treated in time. But on the other hand, the current treatment is also very toxic, and in many cases also results in the patient's death. African sleeping...

A new way of looking at molecular motors

... blindness and kidney disease to neurodegenerative disorders and parasitic diseases such as malaria. All complex organisms use myosin and its relatives, kinesin and dynein, to move substances around inside cells and to help cells move from one place to the other. Myosins also help parasites enter and infect ...

Morning grogginess more debilitating than sleep deprivation, according to CU-Boulder study

The subjects also spent several hours each day during their six-day, in-patient stay practicing the math test used to quantify sleep inertia. "These were ver...

Mice lacking social memory molecule take bullying in stride

Olivier Berton and Eric Nestler, University of Texas Southwestern Medical Center (UTSMC), and colleagues, report on their st...

It's in the genes: Study opens door to new treatment of the blues

...ing mechanisms in the brain underlying psychiatric disorders that have a social withdrawal component, such as social phobia, depression and post-traumatic stress disorder, and that will allow us to find better ways to treat these disorders," Bolanos said. "This study is significant because it gives us an anima...

How 'hot' emotional brain interferes with 'cool' processing

...s has been that people suffering from such anxiety disorders such as depression and PTSD, may see the world differently than other people, and that a distracter associated with trauma may grab control of brain processing and essentially take off-line those areas of the brain we use to stay on task. It's as if ...

"If you understand mechanistically how something works, then you will know how best to fix it," said Knudsen. "It's like with a car; if you know in detail how it is built, then you can fix anything that goes ...

First SCID gene chip to be introduced at Academy meeting on immunodeficiencies

...nodeficiencies (PI) is a group of life threatening disorders that afflict millions of people in the U.S. and around the world.
