An analytical method is developed that allows one to explore the way in which the geometrical structure of a neuron's dendritic tree affects the time-course and amplitude of transient potentials generated at different locations on dendritic branches. The method requires that, for a given dendritic arborization, one associates a symmetric geometry for which exact mathematical expressions for tim...

Current therapeutic windows for effective application of thrombolytic agents are within 3-6 h of stroke. Although treatment can improve outcome, it is unclear what happens to synaptic fine structure during this critical period in vivo. The relationship between microcirculation and dendritic spine structure was determined in mouse somatosensory neurons during stroke. Spines were, on average, 13 ...

Background & Objectives: Chronicity of lupus nephritis (LN) should be considered for interaction of cell mediated immunity (CMI) and dendritic cells in glomeruli and tubulointerstitial areas. In this study establishment of immunohistopathological changes of dendritic cells and other immune effector cells in lupus nephritis comparing with non-lupus nephritis was performed. Materials & Methods: ...

The dendritic field of a neuron, which is determined by both dendritic architecture and synaptic strength, defines the synaptic input of a cell. Once established, a neuron's dendritic field is thought to remain relatively stable throughout a cell's lifetime. Perturbations in a dendritic structure or excitatory tone of a cell and thus its dendritic field are cellular alterations thought to be co...

background: dendritic cells (dcs) are the most potent stimulators of primary t cell responses and play a key role in immune reactions after stem cell transplantation. very little is known about the cord blood (cb) dendritic cells and their potential involvement in the low incidence and lower severity of acute graft-versus-host disease after cb transplantation.   objectives: the aim of this stud...

Drosophila dendritic arborization (da) neurons contain subclasses of neurons with distinct dendritic morphologies. We investigated calcium/calmodulin-dependent protein kinase II (CaMKII) regulation of dendritic structure and dynamics in vivo using optically transparent Drosophila larvae. CaMKII increases the dynamic nature and formation of dendritic filopodia throughout larval development but o...

introduction: decidua as the nearest mother's tissue layer to the fetus which is in direct contact with the embryo has an important role in composing the appropriate microenvironment for protection of allogenic fetus from mother's immune response. in this study the effect of supernatant from culture of decidual cells on dendritic cells regarding the induction of t-cell allogenic proliferation r...

Differential innervation of segregated dendritic domains in the chick nucleus laminaris (NL), composed of third-order auditory neurons, provides a unique model to study synaptic regulation of dendritic structure. Altering the synaptic input to one dendritic domain affects the structure and length of the manipulated dendrites while leaving the other set of unmanipulated dendrites largely unchang...
