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 ...
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...
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 ...
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...
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...
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...
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 ...
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...
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...
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...
