An increased number of microglial cells and reduced arborization
, which suggests activation, were also found in the hippocampus and the striatum of young rodents following embryonic polyriboinosinic-polyribocytidylic acid (Poly I:C) exposure [68, 69], which is proposed to recapitulate disrupted brain-immune interactions associated with schizophrenia and autism.
Rapid Golgi staining was used to visualize dendritic arborizations
and spines, and routine Nissl staining was applied to visualize the somatic configuration of the PCs.
of the deep branch of the ulnar nerve into the interossei and lumbricals.
Identification of three classes of multiglomerular, broad-spectrum neurons in the crayfish olfactory mid-brain by correlated patterns of electrical activity and dendritic arborization
While hearing aids (HAs) can partially compensate for cochlear deficits by amplifying high-frequency sounds, long-standing peripheral hearing loss will also produce neuroplastic alterations within the central auditory system, including changes in synaptic connections and dendritic arborization
In a rat model of stroke, anti-Nogo-A antibody treatment increased dendritic arborization
and spine density .
Beyond its effects over the tau protein, the canonic signaling of the Wnt pathway has been involved in the development of dendritic arborization
, and it also modules the expression of some synaptic proteins like the synaptophysin and the PSD95.
CONCLUSIONS: Our findings demonstrate that environmentally relevant levels of NDL PCBs modulate neuronal connectivity via RyR-dependent effects on dendritic arborization
. In addition, these findings identify RyR channel dysregulation as a novel mechanism contributing to dysmorphic dendritogenesis associated with heritable and environmentally triggered neutodevelopmental disorders.
The relatively small number of GLU-LIR neurons, combined with rich arborization
and projection patterns at both central (ganglion neuropil, connectives and commissures) and peripheral (nerves and tissue) levels, indicate a broad involvement of this amino acid in different regulatory processes, including intra- and interganglionic integration, as well as afferent and efferent roles.
Anatomic study of variations of hypothenar muscles and arborization
patterns of the ulnar nerve in the hand.
Boucher et al described vasoformative structures in 10 of their cases, consisting of microacinar structures, arborization
of microtissue fragments, intracytoplasmic lumens, and signet ring cells.
Reduced dendritic arborization
and spine density phenotypes were observed in rodent models expressing disease-linked mutations (R521C, R521G) in FUS [116, 117], suggesting that disease-mutants may act with a dominant gain-of-function toxicity.
