Anesthetic Sevoflurane Causes Rho-Dependent Filopodial Shortening in Mouse Neurons. [PDF]
Early postnatal anesthesia causes long-lasting learning and memory impairment in rodents, however, evidence for a specific neurotoxic effect on early synaptogenesis has not been demonstrated.

Truncated TrkB receptor-induced outgrowth of dendritic filopodia involves the p75 neurotrophin receptor [PDF]
The Trk family of receptor tyrosine kinases and the p75 receptor (p75NTR) mediate the effects of neurotrophins on neuronal survival, differentiation and synaptic plasticity. The neurotrophin BDNF and its cognate receptor tyrosine kinase, TrkB.FL, are highly expressed in neurons of the central nervous system. At later stages in postnatal development the

Actin capping protein regulates postsynaptic spine development through CPI-motif interactions
Dendritic spines are small actin-rich protrusions essential for the formation of functional circuits in the mammalian brain. During development, spines begin as dynamic filopodia-like protrusions that are then replaced by relatively stable spines ...

Combinatorial morphogenesis of dendritic spines and filopodia by SPAR and α-actinin2 [PDF]
Rap small GTPases regulate excitatory synaptic strength and morphological plasticity of dendritic spines. Changes in spine structure are mediated by the F-actin cytoskeleton, but the link between Rap activity and actin dynamics is unclear. Here, we report a novel interaction between SPAR, a postsynaptic inhibitor of Rap, and alpha-actinin, a family of ...

Calcium Sensors STIM1 and STIM2 Regulate Different Calcium Functions in Cultured Hippocampal Neurons
There are growing indications for the involvement of calcium stores in the plastic properties of neurons and particularly in dendritic spines of central neurons.

Transient Effects of Anesthetics on Dendritic Spines and Filopodia in the Living Mouse Cortex [PDF]
Background Anesthetics are widely used to induce unconsciousness, pain relief, and immobility during surgery. It remains unclear whether the use of anesthetics has significant and long-lasting effects on synapse development and plasticity in the brain. To address this question, the authors examined the formation

Myosin IIb activity and phosphorylation status determines dendritic spine and post-synaptic density morphology. [PDF]
Dendritic spines in hippocampal neurons mature from a filopodia-like precursor into a mushroom-shape with an enlarged post-synaptic density (PSD) and serve as the primary post-synaptic location of the excitatory neurotransmission that underlies learning ...

A two-step actin polymerization mechanism drives dendrite branching
Background Dendrite morphogenesis plays an essential role in establishing the connectivity and receptive fields of neurons during the development of the nervous system. To generate the diverse morphologies of branched dendrites, neurons use external cues
