The molecular machinery at synapses

My group is interested in molecular mechanisms underlying higher brain functions such as memory and learning

The basic questions that we are addressing are:-
How do synapses function on the molecular level?
How is the function of synapses regulated?

Towards these goals we are analyzing the molecular signaling related to glutamate receptors, such as NMDA and AMPA receptors, in wild-type mice, or mutant mice with impaired spatial learning, or mutant mouse models for neurological diseases.


Projects include the analysis of the network of signaling molecules at synapses by advanced proteomic means [1]. This project will extend to the analysis of a mutant mouse strains for human neurologicla diseases. Further projects will analysis of specific signaling pathways [2], structure-function studies on selected molecules of interest [3], and/or the generation and analysis of engineered mouse models [4].
