Séminaire impromptu - Robert Kalb"The intricacy of glutamatergic synapses – some new players in the game"

Abstract :

During early postnatal life, synaptic activity within circuits sculpt connectivity among neurons. NMDA-R mediated activity-dependent development during a critical period has been well explored and other pathways exist, operate in parallel, that are NMDA-R independent.  Evidence is provided for a plasticity channel that involves AMPA-R assembled with GluA1, the synaptic scaffolding protein SAP97 and specific SAP97-binding partners including CRIPT.  
While the cell biological processes governed by GluA1/SAP97/CRIPT are just beginning to be explored, they are likely to be critical for normal brain function.
