G protein-coupled receptors cool passion of 'kiss and run' nerve cells

A new subtlety in the process of how the body's nervous system relays information may hinge on how "wet" the "kiss" is when one neuron fires a packet of neurotransmitter across a synapse to a receptive nerve cell.

Coffee good or bad for you? It depends on your genes!

Scientists know that coffee, a major source of caffeine, is metabolized by the enzyme, cytochrome P450 1A2, and some individuals who have that particular gene are "rapid" caffeine metabolizers, whereas those with a different variation of the gene are "slow" caffeine metabolizers.

Reparative cells offers new avenue for fighting multiple sclerosis

Plaques that form around the nerve cells of people with multiple sclerosis are apparently what disable people with the disease. But partly developed reparative cells within the plaques provide hope for a treatment, a UT Southwestern physician reports in the New England Journal of Medicine.

Attaching new cytokine to neural stem cells derived from bone marrow kills brain tumor cells

Attaching a recently discovered cytokine to neural stem cells derived from bone marrow, researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute have developed a tool to track and kill malignant brain tumor cells and provide long-term protection against their return.
