Scientists solve structure of key protein in innate immune response

...inds to substances liberated from the bacteria and initiates the cellular defense mechanisms. In a report published in the Journal of Biological Chemistry, scientists in Korea announced their elucidation of three-dimensional structure of CD14 and showed how it is perfectly suited to bind to certain bacterial p...

Epstein-Barr virus protein crucial to its role in blood cancers

... human B cells gets a jump start, which ultimately initiates uncontrolled growth. EBV, a member of the herpesvirus family and one of the most common human viruses, plays a role in cancers such as lymphoproliferative diseases in transplant or AIDS patients, Burkitt's lymphoma, Hodgkin's lymphoma, and nasophary...

Stopping smallpox in its tracks: A new anti-viral approach

...gets the erbB-1 signaling molecule, which normally initiates an intracellular cascade that facilitates viral replication. This study shows that drugs that interfere with erbB-1 signaling inhibit SPGF-induced viral replication and spread. The authors show that treatment with these erbB-1 inhibitors are effectiv...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

... by the p53 tumor suppressor protein, kicks in. It initiates the process of programmed cell death, or apoptosis, which directs the cell to commit suicide, permanently removing the damaged DNA from the organism. Since the p53 protein is able to trigger such drastic action as cellular suicide, the cells of the ...

Study Finds Moderate Hypothermia A Safe Treatment For Traumatic Brain Injury In Kids

...a safe therapeutic intervention for children. TBI initiates several metabolic processes that can exacerbate the injury. Adult research has produced evidence that hypothermia may limit some of these deleterious metabolic responses. The trial, which is the only multi-center clinical trial involving children un...

Researchers seek to discover what really happens when a virus enters the body

Study provides insight into cellular defenses against genetic mutation

...ioneer" round checks all new mRNAs for errors, and initiates NMD when errors are detected. A second "steady-state" round translation then directs the mass production of normal proteins based on "NMD-approved" mRNAs. Recently, Maquat's team has worked to identify the roles of proteins involved in NMD, the focu...

Science's Breakthrough of the Year: Watching evolution in action

...ologists pinned down the identity of a signal that initiates the seasonal development of flowers. Other research focused on a gene involved in stimulating flowering, and another study highlighted a surprising cache of RNA. The Nature of Neutron Stars: In 2005, new instruments yielded vivid insights into the m...

...receptor in our immune system − TLR4 − initiates a long series of reactions that bring on an inflammation, which eliminates the bacteria from our body. Of course, this chain of reactions is strictly controlled, because excessive inflammation can lead to lethal shock. Mice that are able to cope wi...

Experimental drug reverses key cognitive deficits, pathology in Alzheimer's
