The quest for an effective HIV vaccine presents new possibilities, challenges

...not prevent infection could prove beneficial if it prolongs the disease-free period and possibly even reduces virus transmission. If such a vaccine is shown to be successful and is eventually licensed, it would need to be delivered as part of a comprehensive, multifaceted HIV prevention program. ...

UCLA study uncovers clues for why Graves' disease attacks the eyes

...cell death. The team suspects that this mechanism prolongs the survival of older T-cells, causing a cascade of autoimmune problems that spur the body to attack its own tissue. "We think that the extra receptors allow the new antibody and IGF-1 to disrupt the programming of the T-cells," said principal inv...

Human stem cells delay start of Lou Gehrig's disease in rats

...ve cell damage typical of the disease and slightly prolongs life. The grafted stem cells develop into nerve cells that make substantial connections with existing nerves and do not themselves succumb to Lou Gehrig's, also known as amyotrophic lateral sclerosis (ALS). The study is published in this week's issue...

Speeding discovery of the 'human cancer genome'

...pies are ineffective, and no existing drug regimen prolongs survival. While a handful of genes have been linked to liver cancer, "how specific lesions interact to produce its aggressive characteristics remains poorly understood." Lowe's team relied on mice with specific pathological changes known to pla...

Viral protein influences key cell-signaling pathway

... T cells." But scientists don't understand how it prolongs T-cell survival and causes their proliferation. This study's findings offer some clues. It is the latest in a series of studies led by Lairmore that examine how HTLV-1 affects T lymphocytes and causes cancer. The p12 gene is called an "accessory ge...
