abstract = {Nuclear Dbf2-related (NDR) kinases are core components of
the Hippo pathway, which controls neuronal polarity and
neurite growth in the central nervous system (CNS). NDR2 is
the principal NDR kinase in the mouse CNS, where it has been
shown to regulate integrin-dependent dendritic branching as
well as growth and plasticity in hippocampal mossy fibers.
Given the well-established involvement of integrins in
plasticity, we hypothesized that NDR2 might regulate synapse
formation and plasticity through integrin-mediated
mechanisms. In this study, using constitutive NDR2 null
mutant mice, we demonstrate that Ndr2 deficiency leads to a
reduction of T788/789 phosphorylated β1 integrin expression
at synaptic sites both in the hippocampal area CA1 and in
primary hippocampal neurons in vitro. This reduction is
associated with decreased synaptic density in both
conditions and accompanied by reduced long-term potentiation
in the synapses between Schaffer collaterals/commissural
fibers and CA1 pyramidal cells, which could be restored by
activation of integrins with an
arginine-glycine-aspartate-containing peptide, as well as
with mild spatial memory deficits. Together, our results
suggest that NDR2 is involved in integrin-dependent synapse
formation and plasticity in the mouse hippocampus.},
