abstract = {Recent findings show that effective integration of novel
information in the brain requires coordinated processes of
homo- and heterosynaptic plasticity. In this work, we
hypothesize that activity-dependent remodeling of the
peri-synaptic extracellular matrix (ECM) contributes to
these processes. We show that clusters of the peri-synaptic
ECM, recognized by CS56 antibody, emerge in response to
sensory stimuli, showing temporal and spatial coincidence
with dendritic spine plasticity. Using CS56
co-immunoprecipitation of synaptosomal proteins, we identify
several molecules involved in Ca2+ signaling, vesicle
cycling, and AMPA-receptor exocytosis, thus suggesting a
role in long-term potentiation (LTP). Finally, we show that,
in the CA1 hippocampal region, the attenuation of CS56
glycoepitopes, through the depletion of versican as one of
its main carriers, impairs LTP and object location memory in
mice. These findings show that activity-dependent remodeling
of the peri-synaptic ECM regulates the induction and
consolidation of LTP, contributing to hippocampal-dependent
memory.},
