In the postsynaptic density of glutamatergic synapses, the discs large (DLG)-membrane-associated guanylate kinase (MAGUK) family of scaffolding proteins coordinates a multiplicity of signaling pathways to maintain and regulate synaptic transmission. Postsynaptic density-93 (PSD-93) is the most variable paralog in this family; it exists in six different N-terminal isoforms. Probably because of t...
The overall size and structure of a synaptic terminal is an important determinant of its function. In a large-scale mutagenesis screen, designed to identify Drosophila mutants with abnormally structured neuromuscular junctions (NMJs), we discovered mutations in Drosophila mical, a conserved gene encoding a multi-domain protein with a N-terminal monooxygenase domain. In mical mutants, synaptic b...
Background and purpose: Glial cells seem to play role in synaptic plasticity because they have the ability to release trophic factors and gliotransmitters and respond to neurotransmitters. They also play important role in synaptic space homeostasis. In this study, the role of hippocampal glial cells in baseline synaptic response and short term synaptic plasticity were investigated. Material...
The C-terminal PDZ ligand of the AMPA receptor GluR1 subunit may be important for expression of CA1 hippocampal long-term potentiation. To test this directly in vivo, we generated a knock-in mouse lacking the last seven residues of GluR1, comprising the PDZ ligand. This deletion did not affect basal GluR1 synaptic localization, basal synaptic transmission, long-term potentiation or long-term de...
Six mutations in the salt-inducible kinase 1 (SIK1)-coding gene have been identified patients with early infantile epileptic encephalopathy (EIEE-30) accompanied by autistic symptoms. Two of are non-sense that truncate C-terminal region SIK1. It has shown C-terminal-truncated form SIK1 protein affects subcellular distribution protein, tempting to speculate relevance pathophysiology disorders. W...
Neurons are specialized cells with a complex architecture that includes elaborate dendritic branches and a long, narrow axon that extends from the cell body to the synaptic terminal. The organized transport of essential biological materials throughout the neuron is required to support its growth, function, and viability. In this review, we focus on insights that have emerged from the genetic an...
VGF is a neurotrophin-inducible, activity-regulated gene product that is expressed in CNS and PNS neurons, in which it is processed into peptides and secreted. VGF synthesis is stimulated by BDNF, a critical regulator of hippocampal development and function, and two VGF C-terminal peptides increase synaptic activity in cultured hippocampal neurons. To assess VGF function in the hippocampus, we ...
