New vaccine prevents CMV infection and disease in mice

...ented a strategy for developing a human vaccine to prevent against Human Cytomegalovirus (hCMV) infection and disease. CMV, a type of herpes virus, is the leading viral cause of birth defects and a serious problem in patients with compromised immune systems. The body’s natural immunity doesn’t protect ag...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

... painkillers called opioids, which when they dock, prevent the sending of pain messages along nerve pathways. In the current study, researchers used gene therapy to increase by about one thousand times the number of opioid receptors expressed on the surfaces of nerve cells that carry pain messages back a...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

... "We have shown that this technique can work to prevent and neutralise infection by the H5N1 'bird flu' virus in mice," says Dr Cameron Simmons, a Wellcome Trust researcher at the Oxford University Clinical Research Unit, Vietnam. "We are optimistic that these antibodies, if delivered at the right time an...

...usceptibility. Normal versions of these genes help prevent cancer from occurring in the first place, by helping cells to repair DNA breaks and other abnormalities that can result from chance or exposure to an environmental toxin, such as excessive UV sunlight. However, BRCA-1, BRCA-2 and the other previously...

Scripps research team sheds light on long-sought cold sensation gene

...uce cold sensation as an analgesic, or block it to prevent certain forms of chronic pain associated with cold sensation. "This study represents the first demonstration that a single gene is responsible for most cool temperature sensation," says team leader Ardem Patapoutian, who has joint appointments with ...

'Insulator' helps silence genes in dormant herpes virus

...s boundary elements, are DNA segments that work to prevent a gene from being influenced by the activation or repression of its neighbors. About a dozen different insulator elements have been identified in organisms as varied as yeast, fruit flies, and humans. Not simply passive barriers, insulators help o...

What has been missing, according to Blower, a mathematical and evolutionary biologist, is the human factor. The human factor involves two biologic...

Vaccine prevents prion disease in mice

An oral vaccine can prevent mice from developing a brain disease similar to mad cow disease, according to research that will be presented at the American Academy of Neurology's 59th Annual Meeting in Boston, April 28 ?May 5, 2007. Prion diseases, which include scrapie, mad cow ...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...SNO compounds were administered to mice they could prevent the receptors from being "turned off" by the drugs. The researchers said these findings, if confirmed in humans, open up new avenues for the development of non-desensitizing drugs not only for heart failure and asthma but also for other conditions...

Targeting sugar on blood vessels may inhibit cancer growth

In a study that could point to novel therapies to prevent cancer spread, or metastasis, researchers at the University of California, San Diego (UCSD) School of Medicine have targeted a sugar that supports blood vessel growth in the tumor. Their findings will be published in the May 7 on-line issue of Journ...
