A Study Finds VENs Devastated in FTD

...tonin, and vasopressin systems that play important roles in social and emotional bonding. These functions are disrupted early in FTD but spared in AD, the authors note. While drugs aimed at preserving VEN function may help curtail FTD symptoms, basic studies of VEN biophysical and molecular properties are ...

New Drug Offers Promise as Single Treatment for HIV

...reverse transcriptase and protease, which play key roles in the virus' ability to reproduce itself. MK-0518 targets a "third enzyme" called integrase, which is found only in HIV and is essential to the virus' ability to insert its DNA into human genes. By blocking integrase, MK-0518 blocks HIV's ability ...

High Testosterone Destroys Nerve Cells

... The key male hormone testosterone plays elemental roles in development, differentiation, and cellular growth. In nerve cells testosterone functions as a neurosteroid and can bring on changes at the cellular level, as a consequence of which, changes in behavior, mood and memory are brought about.

New Path from Estrogen to Survival in Breast Cancer Cells Described

...e of the journal, Nature Cell Biology, they assign roles to a number of genes and proteins thought to play a part in breast cancer cell survival, and in the process, have identified potential molecular drug targets. "It's a very complex story, but we have been able to bring together a number of basic dis...

Link between Fish and Mammal Immune Systems Revealed by Killer B cells

...mune cells in fish but also may point out to novel roles of B cells in mammals. At this point, we cannot rule out the possibility that small subpopulations of phagocytic B cells, perhaps remnants of those present in fish, are still present in mammals, Sunyer said.

Cooling Temperatures Help Crucian Carp

...lycogen and the sodium pump play equally important roles in carrying the fish through the anoxic period. The glycogen level that supports brain function for 16 hours in the anoxic winter when energy demand is low, would support the fish for only eight minutes in the summer with the same amount of oxygen. T...
