Sugar-binding protein may play a role in HIV infection
2011-06-16
(Press-News.org) Though it is known that PDI inhibitors can prevent HIV infection, just how this happens has remained a mystery. And though it has been known that PDI, which normally lives inside the cell, can become entrapped on the cell's surface, it has not been understood how this happens.
Now, in a new study, UCLA researchers report that a sugar-binding protein called galectin-9 traps PDI on T-cells' surface, making them more susceptible to HIV infection.
IMPACT:
The findings could lead researchers to a potential new target for anti-HIV therapeutics, such as therapies to inhibit PDI or galectin-9.
INFORMATION: AUTHORS:
Shuguang Bi, Patrick W. Hong, Benhur Lee and Linda G. Baum, all of UCLA
JOURNAL:
The research appears in the journal Proceedings of the National Academy of Sciences (http://bit.ly/jko3Me).
FUNDING:
The National Institutes of Health supported the study.

Before making the vital decision of which personal injury solicitor you contact, there are a few pieces of information that you should be clear on regarding the incident in question.
If you believe that you have been the victim of an act of medical negligence or personal injury visit your General Practitioner as soon as possible for supportive evidence of your injuries. If involved in a traffic accident the same applies and injuries should be documented in a medical report for potential use in your case
If the circumstances dictate (such as a traffic or pedestrian ...

Motivation to change, confidence to resist temptation, should tailor alcohol-dependence treatment
People seeking help for their alcohol or other drug problems enter treatment with very different levels of motivation to change. Differences in motivation appear to make a critical difference in which patients seek, comply with, and complete treatment. Findings from a study of the extent to which motivation and ...

Understanding alcohol's damaging effects on the brain
While alcohol has a wide range of pharmacological effects on the body, the brain is a primary target. However, the molecular mechanisms by which alcohol alters neuronal activity in the brain are poorly understood. Participants in a symposium at the June 2010 annual ...

HOUSTON - (June 15, 2011) – When Noah and Alexis Beery were diagnosed with cerebral palsy at age 2, their parents thought they at last had an answer to the problems that had plagued their twin infants from birth. However, that proved only a way station on a journey to find an answer to the children's problems that combined their mother's determination, the high tech world of next-generation sequencing in the Baylor Human Genome Sequencing Center (http://www.hgsc.bcm.tmc.edu/) (HGSC) and the efforts of talented physicians from across the country.
In a report in the current ...

This example of an employment law Q&A reinforces the need to find a good employment solicitor to explain its intricacies.
What is the procedure when a former employee decides to sue for unfair dismissal?
The former employee would submit the form ET1 detailing the complaint, their personal information and any remedy sought. Employment solicitors can ensure this is done correctly.
Upon receipt of the ET1 the employer must respond with form ET3 within 28 days outlining the particulars of their response.
The parties involved will then enter the 'conciliation process' ...

An international consortium of researchers report today in Nature that they have knocked out almost 40 per cent of the genes in the mouse genome. The completed resource will power studies of gene activity in models of human disease.
The results are founded on a novel, efficient production line that is able to target each specific gene in turn. The consortium has cracked all the challenges of generating mutations of each gene in mouse embryonic stem cells, and has already knocked out 9,000 genes in the mouse genome as part of an international effort to knockout all 21,000. ...

In a new study published today in the journal Nature, scientists discovered an entirely new way to change the genetic code. The findings, though early, are significant because they may ultimately help researchers alter the course of devastating genetic disorders, such as cystic fibrosis, muscular dystrophy and many forms of cancer.
The genetic code is the set of instructions in a gene that tell a cell how to make a specific protein. Central to the body's protein production process is messenger RNA, or mRNA, which takes these instructions from DNA and directs the steps ...

New Haven, Conn.—Astronomers have been peering farther and farther into space, and back in time, using the world's most powerful telescopes to detect galaxies billions of light years away that existed when the universe was just a fraction of its current age. But detecting the giant black holes thought to lurk at the centers of those galaxies has proven much more difficult.
Now a team of astronomers has discovered the earliest black holes ever detected, despite the fact that they are hidden from view by their host galaxies. They also measured the average growth rate of ...

Debenhams has revealed that the de rigueur way for British men to wear their shirts this season is with three buttons undone, otherwise known as the 'shirtego' trend.
Last seen on seventies lotharios such as Richard Gere in 'American Gigolo' and John Travolta in 'Saturday Night Fever', the bare chest has marked the return of the 'machosexual' - men who are not afraid to be masculine, confident and sexy.
Department store, Debenhams asked its customers, "how low can you go?" and found that 75 per cent of men now regularly wear their shirt with three buttons ...
