Brain protein may be a target for fast-acting antidepressants

It takes weeks or months for the effect of most antidepressants to kick in, time that can feel like an eternity to those who need the drugs the most. But new research suggests that a protein called p11, previously shown to play a role in a person's susceptibility to depression, activates a serotonin receptor in the brain known for producing

Researchers identify molecule that helps the sleep-deprived to mentally rebound

Sleep experts know that the mental clarity lost because of a few sleepless nights can often be restored with a good night's rest. Now, UT Southwestern Medical Center researchers have identified a key molecular mechanism that regulates the brain's ability to mentally compensate for sleep deprivation.

Researchers block immune cell rush behind deadly sepsis

Researchers have found a way to block the ability of white blood cells to sprint toward the sites of infection when such speed worsens the damage done by sepsis, the often fatal, whole-body bacterial infection, according to a study published today in the journal Blood.

Nanoparticles detect dying cancer cells

Two years ago, researchers at the University of South Australia discovered a new molecular marker specific for chemotherapy-induced cancer cell death. Now, those same investigators have used this marker to develop an imaging agent that can pinpoint tumor cell death using magnetic resonance imaging.
