Study identifies key aspect of immune response against HIV
...entified immune-system genes that appear to play a key
role in the body's defense against HIV, the virus that causes AIDS. The findings may lead to ways of circumventing the virus's ability to avoid vaccines by rapid mutation. The study in the Dec. 9 issue of Nature also describes how HIV infection i...

UCSB makes important advances in studies of retinal detachment
...ondon. Understanding the "glial" response is a key
aspect of this study. Glial cells are known as the "supporting cells" of the nervous system. The central nervous system (CNS) consists of both neurons and glial cells. Glial cells actually outnumber neurons in the CNS but their functions are poo...

finding is that a galanin receptor antagonist by itself reduces alcohol drinking," observed Thiele. "This suggests a possible role for galanin receptor antagonists in the treatment of uncontrolled alcohol drinking, otherwise known as alcohol depende...
New route to Parkinson's found in cells' 'garbage disposal' system
Researchers have known that mutations in a key
gene called parkin are a major cause of Parkinson's disease (PD). Now they have discovered a new mechanism by which the parkin gene can be compromised, a finding that they say could lead to new drugs for the disorder. Andrea Lozano, Senior Scientist ...
Loss of fruit fly retina protein delays blinding light damage
