  1. Enkephalin co-expression with classic neurotransmitters in the amygdaloid complex of the rat.

    Journal of Comparative Neurology 506(6):943 (2008) PMID 18085591

    This study aimed at characterizing the neurotransmitter phenotype of enkephalin neurons in the rat amygdaloid complex. We first established the detailed distribution of vesicular glutamate transporters 1 and 2 (VGLUT1 and -2) and glutamate decarboxylase 65 (GAD65) in the amygdala by using in sit...
  2. Repopulation of cochlear macrophages in murine hematopoietic progenitor cell chimeras: the role of CX3CR1.

    Journal of Comparative Neurology 506(6):930 (2008) PMID 18085589

    Cochlear macrophages have been shown to accumulate in the murine cochlea following acoustic trauma. This investigation was performed to determine whether cochlear macrophages could be replaced by donor transplantation of bone marrow precursors. Lethally irradiated C57BL/6 mice were transplanted ...
  3. Bulbospinal neurons of the rat rostromedial medulla are highly collateralized.

    Journal of Comparative Neurology 506(6):960 (2008) PMID 18085592

    The rostromedial medulla participates in a large variety of sensory, motor, and autonomic functions. We asked whether individual bulbospinal neurons in this region have localized, target-specific terminal arbors or whether they collateralize broadly in the spinal cord. Collateralization was quan...
  4. Differential localization of GABAA receptor subunits within the substantia nigra of the human brain: an immunohistochemical study.

    Journal of Comparative Neurology 506(6):912 (2008) PMID 18085588

    Gamma-aminobutyric acid(A) (GABA(A)) receptors (GABA(A)R) are inhibitory heteropentameric chloride ion channels comprising a variety of subunits and are localized at postsynaptic sites within the central nervous system. In this study we present the first detailed immunohistochemical investigatio...
  5. Expression of receptors for glial cell line-derived neurotrophic factor family ligands in sacral spinal cord reveals separate targets of pelvic afferent fibers.

    Journal of Comparative Neurology 506(6):989 (2008) PMID 18085594 PMCID PMC3049865

    Nerve growth factor has been proposed to mediate many structural and chemical changes in bladder sensory neurons after injury or inflammation. We have examined the expression of receptors for the glial cell line-derived neurotrophic factor (GDNF) family within sensory terminals located in the sa...
  6. Molecular characterization and comparative localization of the mRNAs encoding two glutamic acid decarboxylases (GAD65 and GAD67) in the brain of the African lungfish, Protopterus annectens.

    Journal of Comparative Neurology 506(6):979 (2008) PMID 18085593

    The existence of two distinct genes encoding two isoforms of glutamic acid decarboxylase (GAD65 and GAD67) has been demonstrated in most vertebrate classes, yet little is known about their differential distributions and functions in the central nervous system in nonmammalian vertebrates. In the ...
  7. Lead exposure during development results in increased neurofilament phosphorylation, neuritic beading, and temporal processing deficits within the murine auditory brainstem.

    Journal of Comparative Neurology 506(6):1003 (2008) PMID 18085597

    Low-level lead (Pb) exposure is a risk factor for learning disabilities, attention deficit hyperactivity disorder (ADHD), and other neurological dysfunction. It is not known how Pb produces these behavioral deficits, but low-level exposure during development is associated with auditory temporal ...
  8. PI3K signaling effects in hypothalamic neurons mediated by estrogen.

    Journal of Comparative Neurology 506(6):895 (2008) PMID 18085586

    Multiple mechanisms mediate the effects of estrogen in the central nervous system, including signal transduction pathways such as protein kinase A, protein kinase C, and phosphatidylinositol 3-kinase (PI3K) pathways. Previously we demonstrated that estrogen regulates a number of PI3K-related gen...
  9. Characterization of nitric oxidergic neurons in the alimentary tract of the snail Helix pomatia L.: histochemical and physiological study.

    Journal of Comparative Neurology 506(5):801 (2008) PMID 18076086

    By using NADPH-diaphorase (NADPH-d) histochemistry, nitric oxide synthase (NOS) immunohistochemistry, Western blotting, and NO pharmacology, we investigated the distribution and possible function of NOS-containing neurons in different units of the alimentary tract of the snail, Helix pomatia. Di...
  10. Molecular dynamics of photoreceptor synapse formation in the developing chick retina.

    Journal of Comparative Neurology 506(5):822 (2008) PMID 18076030

    The cellular and molecular mechanisms underlying photoreceptor synaptogenesis are poorly understood. Furthermore, a detailed picture of the molecular composition of photoreceptor synapses, or their subtypes, is not yet available, nor do we know what differences, if any, exist among those subtype...
