Recent advances in the study of long-term potentiation(part II)--transgenic study of LTP
Abstract：There is more and more evidence showing long term potentiation (LTP) is underling learning and memory even though it is still controversy and the mechanism behind LTP has not yet been completely understood. It is known that memory processes and long-term potentiation (LTP) are blocked at the time of their initiation by antagonists of glutamate NMDA or metabotropic receptors, and GABA-A receptor agonists. Following initiation, memory and LTP are accompanied by an enhancement of the activity of calcium/calmodulin-dependent protein kinase II and of protein kinase C. At the time of expression, LTP is blocked by antagonists of glutamate AMPA receptors. In recent five years, with advanced molecular biology techniques, scientist could use transgenic and knock out mice to explore what happens to LTP and learning and memory when specific disease related or novel gene was overexpressed or deleted. Therefore cellular and molecular mechanisms of activity-dependent synaptic plasticity are understood in a new level. Here we introduced recent research work on LTP with transgenic approach in hope to inspire interest in genomic and protenomic technology. We will continue to discuss BDNF and LTP and introduce some interesting LTP related work in part III.
