How HIV 'exhausts' killer T cells

... testing of drugs that block the PD-1 switch could begin very soon, since such drugs exist already. However, he cautioned that these kinds of drugs could cause serious side effects, including autoimmune reactions that trigger the immune system to attack the body. Walker added that the researchers' findings...

Neurons grown from embryonic stem cells restore function in paralyzed rats

...ls might be used to treat injuries and disease and begin to fulfill their great promise. The successful demonstration of functional restoration is proof of the principle and an important step forward. We must remember, however, that we still have a great distance to go," says Elias A. Zerhouni, Director of...

BGSU biologist trying to crack microscopic code

... and asking what's important and what isn't. "To begin understanding how proteins talk, we first made random mutations--we broke things and then asked what happened," Larsen says. "That strategy worked well and allowed us to identify the key 'words.' Now we want to know what the 'words' mean, and we are ...

Virtual realities against pain

...nalgesic administered. This new field of study can begin to move forward beyond its current initial phase by placing more emphasis on methodology and psychological aspects. ...

Adult stem cells are touchy-feely, need environmental clues

...of Engineering and Applied Science. "The results begin to establish a physical basis for both stem-cell use against diseases and for stem-cell behavior in embryonic development," Much of the work in stem-cell science has involved the study of the chemical microenvironment, the soup of chemical messeng...

Genetic tug of war determines sexual differentiation

...p along male or female pathways. Capel's team will begin a new study this summer to better understand the role of temperature on sex determination in a turtle that she hopes can shed light on the general issue of sex determination in vertebrates. ...

Mitochondrial DNA sequencing tool updated

.... Now, you can sequence the D loop so readily and begin to look harder for associations in certain cancers."...

A more powerful and efficient engine for rice: the C3-C4 challenge

...sts will have assembled the tools and materials to begin constructing the prototypes of a C4 rice plant. It will be another 10?5 years after that before the first varieties are available. "Considering the urgent rice production challenges we face, we must start now on this work--there's no time to lose,...

Marine 'dead zone' off Oregon is spreading

... seeing that pool of water come close to shore and begin to suffocate marine life. If these winds continue to blow, we expect to see continued and possibly significant die-offs." As events such as this become more regular, researchers say, they appear less like an anomaly and more like a fundamental shif...

UAB researchers confirm HIV-1 originated in wild chimpanzees

...behavior of SIVcpz in its natural host and help us begin to unravel how and why SIVcpz made the jump to humans." ...

In-home sensors spot dementia signs in elderly

... and her colleagues predict that as healthy elders begin to develop cognitive impairment, they become more variable day to day or even hour to hour, and that "this variability may provide an early marker that can be used to predict the later onset of dementia in a single individual." They have already begu...

Iron critical to ocean productivity, carbon uptake

...on, they just take off. They don't have to wait to begin dividing and growing. But that green color wasn't an indication of health, it was an indication of stress from a lack of iron." The study is also important because it looked at the availability of iron throughout the tropical Pacific Ocean instead o...

Mosquito spray increases toxicity of pyrethroids in creek, study finds

...on (DPR) announced earlier this month that it will begin re-evaluating some 600 pyrethroid-containing products. The re-evaluation process will likely help determine what urban pesticide use practices are leading to pyrethroids finding their way into creeks. "We don't know yet if the source is a product a...

UF scientists test improved gene therapy method for hereditary heart conditions

...rch, pave the way for studies in humans that could begin as soon as early next year for patients with Pompe... known as dilated cardiomyopathy. But efforts to begin testing it in people have been slowed by the need to find ways to deliver corrective genes easily an...

Better beetle sought for salt cedar control

New device could cut chemotherapy deaths

...arian cancer in Avon, Somerset and Wiltshire could begin in the next few years and, if successful, the technology could be put into general use. The research team at Bath is collaborating closely with the Avon, Somerset and Wiltshire Cancer Centre and the oncology team at the Royal United Hospital for the...

Cancer virus protein needed for successful infection

...th, or apoptosis. "These findings should help us begin to learn whether this viral protein influences cell survival, perhaps by extending the life of the cell," Lairmore says. HTLV-1 infects an estimated 15 to 20 million people worldwide. About 5 percent of those infected develop adult T cell leukemia ...

Discovery may speed forest biotechnology

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

... the T cells disengage from the dendritic cell and begin to rapidly reproduce. About three days later, they depart from the lymph node on their search-and-destroy mission. Homing in on the target T cells patrol the body by hitching a ride in the blood, methodically stopping at each lymph node like a ni...

One big biology question solved

... Vitamin A, causes germ cells in female embryos to begin meiosis, leading to the production of eggs. They also discovered an enzyme present in male embryos that wipes out retinoic acid and so suppresses meiosis until after birth, resulting in sperm production. "This is an extremely important process th...
