Mitochondria Key to Glutamate Toxicity

Glutamate is a neurotransmitter that is toxic when too much of it is released by excessive neuronal activity or by brain injury. Some researchers have also proposed that glutamate toxicity drives the neurodegeneration...

How NF-κB Derails Apoptosis

A study published in tomorrow's Science provides new details of how the transcription factor NF-κB protects cells from apoptosis. C.-Y. Wang and colleagues report they have identified four genes that are targets of NF-κB activity...

Dopamine Transporter Imaging

A novel brain-imaging agent that binds selectively to dopamine transporter molecules promises to open up a window on the functioning of the brain's dopamine system. Dopamine is one of the brain's major neurotransmitters...

Potential NGF Drug-Delivery System

Puny polymer pellets show promise as a vehicle for delivering nerve-growth factor (NGF) to the basal forebrain, where the substance could rescue or even regenerate neurons damaged by Alzheimer's disease...

Epilepsy Drugs Effective for Agitation in AD

For many families caring for an Alzheimer's patient, it is not the memory impairment per se that drives them to place their loved one in a nursing home, so much as the agitation, aggression and even violence that demented patients frequently exhibit...

Membrane Rafts Revealed

It has been theorized that cell membranes contain stable regions consisting of glycolipids and cholesterol. They are called detergent-insoluble glycolipid-enriched membrane domains (DIGs)...

Resisting Apoptosis

Transcription factors of the nuclear factor-kB/rel (NF-kB) family may be important in cell survival by regulating unidentified, antiapoptotic genes. One such gene that protects cells from apoptosis...

Cholinergic Switching

Acetylcholine has different effects on the excitability of different neuronal types, according to work by Xiang, et al, published in today's Science. The researchers examined two subtypes of interneurons in layer V of rat visual cortex...

More Clues to Diet and Aging

Maybe it is time to give up steak in order to live longer—at least if you are a fruit fly. According to a study published today in Science, a diet of sugar keeps flies in a metabolic "waiting mode," in which both reproduction and death rates are low...
