Scientists Examine HIV's Effect On Immune System
A study by researchers from Duke University and the University of North Carolina-Chapel Hill and published in PLoS Medicine has found that upon infection "three lines of attack by the immune system are quickly neutralized by HIV," findings they hope "will provide a better understanding of how to develop a vaccine to protect against the virus," the Raleigh News & Observer reports. The study, lead by Duke"s Barton Haynes, showed that HIV, "once considered a slow if stealthy invader, actually works incredibly fast at disarming key immune fighters in the body." Haynes said scientists still have a difficult task in developing a vaccine, adding, "It would have to be different than any other vaccine made" (Avery, 7/7).

Researchers Uncover Proteins Underlying Devastating Brain Diseases
Scientists at the Wellcome Trust Sanger Institute have discovered a set of brain proteins responsible for some of the most common and devastating brain diseases. The proteins underlie epilepsy, depression, schizophrenia, bipolar disease, mental retardation and neurodegenerative diseases including Alzheimer"s and Huntington"s diseases.

Sufferers Of Lung Diseases May Be Helped By Placenta-Derived Stem Cells
An Italian research team, publishing in the current issue of Cell Transplantation (18:4), which is now available on-line without charge at http://www.ingentaconnect.com/content/cog/ct, has found that stem cells derived from human placenta may ultimately play a role in the treatment of lung diseases, such as pulmonary fibrosis and fibrotic diseases caused by tuberculosis, chemical exposure, radiation or pathogens. These diseases can ultimately lead to loss of normal lung tissue and organ failure. No known therapy effectively reverses or stops the fibrotic process.

UK To Play Lead Role In European Fight Against Dementia

The UK will play a leading role in coordinated European action to tackle dementia from. A new initiative launched by the European Commission has adopted proposals to tackle Alzheimer"s disease, dementias and other neurodegenerative conditions. The UK is one of ten countries that will lead research aimed at tackling shared health and social care problems. According to the Commission there are over seven million people with Alzheimer"s disease and related disorders in Europe and it is predicted that this number will double in the next 20 years. Today"s actions mark new steps both in the Commission"s "Europe for Patients campaign" and the new approach of Joint Programming in research. Dr Susanne Sorensen, Head of Research, Alzheimer"s Society says, "Building on successful high impact dementia research, the UK will play a critical role in this initiative, leading the fight to defeat dementia. By uniting to find a cause, cure and fund care, we can galvanise our efforts and offer hope to millions of people. "But while Europe strives forward, the UK government still lags behind the US, Germany and France in providing dementia research funding and there is still no specifically targeted dementia research funding. Yesterday the government promised to develop a strategy for investment in dementia research. It must make good on its promises or we will all pay the price." In an open letter to the government yesterday, 31 leading dementia researchers united to call for a national plan for dementia research and a tripling of current investment. The letter coincides with a unique ministerial research summit on dementia which stated the importance of increasing research funding spent on dementia. Experts agree the UK must follow the French model for dementia research which provides a focussed structure to support the full breadth of cause, cure and care research. Alzheimer"s Society
