Untangling Neuronal Calcium Signaling
Amy Adams | Jan 20, 2002 | 10 min read
From the very moment of conception, calcium plays a pivotal role in fetal development. It rushes in as a wave around the egg to herald the sperm's arrival, binding to proteins that help kick off the whole developmental process. From this first influx, calcium continues to play a critical role in how the body's cells respond to outside signals. Calcium tells muscles to contract and nerves to release neurotransmitters, and is at least part of the signal that helps people form and retain memories.
Scientists Strike a Cord

Courtesy of SR Eng  BABY STAINS: The head of a transgenic murine embryo in which a marker enzyme has been specifically expressed in the sensory neurons of the trigeminal and dorsal root ganglia. The marker allows staining of the projections of these neurons into, among other areas, the hindbrain and spinal cord. (S.R. Eng et al., "Defects in sensory axon growth precede neuronal death in Brn3a-deficient mice," J Neurosci, 21:541-9, 2001.) Somewhere in the 200 million bases of the human ge

The Tiniest of Life's Rafts
Jill Adams | Oct 10, 2004 | 6 min read
LIPID RAFTS INSIDE AND OUT:© 2002 AAASIn the outer leaflet (A), sphingolipids and cholesterol form less fluid microdomains (B) called lipid rafts, which are enriched for GPI-proteins. Microdomains may contain more rigid subdomains (C) enriched for the sphingolipid ganglioside GM1. The membrane inner leaflet contains microdomains (D) with unknown lipid composition enriched for prenylated proteins. In contrast, caveolin and proteins carrying the two saturated fatty acyl chains become concentr
