Npas4: Molecular Mechanisms Of Memory Formation

MIT neuroscientists have uncovered a cellular pathway that allows specific synapses to become stronger during memory formation. The findings provide the first glimpse of the molecular mechanism by which long-term memories are encoded in a region of the hippocampus called CA3. The researchers found that a protein called Npas4, previously identified as a master controller […]

Sonic Hedgehog Gene Actively Maintains Adult Lung Quiescence

The ‘sonic hedgehog’ gene, best known for controlling embryonic development, also maintains the normal physiological state and repair process of an adult healthy lung, if damaged, according to new research from the Perelman School of Medicine at the University of Pennsylvania. Tissues are not all created equal in their ability to regenerate. Skin and blood […]
