Abstract
The present study investigated the development of the paracervical ganglion in 5-, 7- and 10-week-old porcine foetuses using double labelling immunofluorescence method. In 5-week-old foetuses single PGP-positive perikarya were visible only along the mesonephric ducts. They contained DβH or VAChT, and nerve fibres usually were PGP/VAChT-positive. The perikarya were mainly oval. In 7-week-old foetuses, a compact group of PGP-positive neurons (3144±213) was visible on both sides and externally to the uterovaginal canal mesenchyme of paramesonephric ducts. Nerve cell bodies contained only DβH (36.40±1.63%) or VAChT (17.31±1.13%). In the 10-week-old foetuses, the compact group of PGP-positive neurons divided into several large and many small clusters of nerve cells and also became more expanded along the whole uterovaginal canal mesenchyme reaching the initial part of the uterine canal of the paramesonephric duct. The number of neurons located in these neuronal structures increased to 4121±259. Immunohistochemistry revealed that PGP-positive nerve cell bodies contained DβH (40.26±0,73%) and VAChT (30.73±1.34%) and were also immunoreactive for NPY (33.24±1,27%), SOM (23.6±0,44%) or VIP (22.9±1,13%). Other substances studied (GAL, NOS, CGRP, SP) were not determined at this stage of the development. In this study, for the first time, the morphology of PCG formation in the porcine foetus has been described in three stages of development. Dynamic changes in the number of neurons and their sizes were also noted, as well as the changes in immunochistochemical coding of maturing neurons.

Abstract
Membranous compartments of neurons such as axons, dendrites and modified primary cilia are defining features of neuronal phenotype. This is unlike organelles deep to the plasma membrane, which are for the most part generic and not related directly to morphological, neurochemical or functional specializations. However, here we use multi-label immunohistochemistry combined with confocal and electron microscopy to identify a very large (∼6 microns in diameter), entirely intracellular neuronal organelle which occurs singly in a ubiquitous but neurochemically distinct and morphologically simple subset of sympathetic ganglion neurons. Although usually toroidal, it also occurs as twists or rods depending on its intracellular position: tori are most often perinuclear whereas rods are often found in axons. These ‘loukoumasomes’ (doughnut-like bodies) bind a monoclonal antibody raised against beta-III-tubulin (SDL.3D10), although their inability to bind other beta-III-tubulin monoclonal antibodies indicate that the responsible antigen is not known. Position-morphology relationships within neurons and their expression of non-muscle heavy chain myosin suggest a dynamic structure. They associate with nematosomes, enigmatic nucleolus-like organelles present in many neural and non-neural tissues, which we now show to be composed of filamentous actin. Loukoumasomes also separately interact with mother centrioles forming the basal body of primary cilia. They express gamma tubulin, a microtubule nucleator which localizes to non-neuronal centrosomes, and cenexin, a mother centriole-associated protein required for ciliogenesis. These data reveal a hitherto undescribed organelle, and depict it as an intracellular transport machine, shuttling material between the primary cilium, the nematosome, and the axon.

Abstract
In this review we summarize current understanding of the development of autonomic neurons in vertebrates. The mechanisms controlling the development of sympathetic and enteric neurons have been studied in considerable detail in laboratory mammals, chick and zebrafish, and there are also limited data about the development of sympathetic and enteric neurons in amphibians. Little is known about the development of parasympathetic neurons apart from the ciliary ganglion in chicks. Although there are considerable gaps in our knowledge, some of the mechanisms controlling sympathetic and enteric neuron development appear to be conserved between mammals, avians and zebrafish. For example, some of the transcriptional regulators involved in the development of sympathetic neurons are conserved between mammals, avians and zebrafish, and the requirement for Ret signalling in the development of enteric neurons is conserved between mammals (including humans), avians and zebrafish. However, there are also differences between species in the migratory pathways followed by sympathetic and enteric neuron precursors and in the requirements for some signalling pathways.

Abstract
Sympathetic and parasympathetic postganglionic neurons innervate a wide range of target tissues. The subpopulation of neurons innervating each target tissue can express unique combinations of neurotransmitters, neuropeptides, ion channels and receptors, which together comprise the chemical phenotype of the neurons. The target-specific chemical phenotype shown by autonomic postganglionic neurons arises during development. In this review, we examine the different mechanisms that generate such a diversity of neuronal phenotypes from the pool of apparently homogenous neural crest progenitor cells that form the sympathetic ganglia. There is evidence that the final chemical phenotype of autonomic postganglionic neurons is generated by both signals at the level of the cell body that trigger cell-autonomous programs, as well as signals from the target tissues they innervate.

Abstract
BACKGROUND Cystovaginoplasty (CVP) is a method of vaginal reconstruction in women with Mayer-Rokitansky-Kistner-Hauser Syndrome (MRKHS). The neo-vagina allows normal sexual intercourses, but after CVP, the sexual life of patients with MRKHS does not differ significantly from normal females. Therefore, we decided to elucidate the pattern of sensory re-innervation of the bladder flap used for the surgery. METHODS Biopsies were taken from vaginal vestibule and urinary bladder during the CVP and 1 year later in four patients with MRKHS. The following neurotransmitters were studied calcitonin gene-related peptide (CGRP), galanin (GAL), vasoactive intestinal polypeptide (VIP) and pituitary adenylate cyclase-activating peptide (PACAP). RESULTS CGRP and PACAP nerve fibres were sparse under the urothelium and in submucosal layer of the neovagina, they were more numerous around blood vessels and in the vicinity of smooth muscles. This was similar to the pattern observed in the urinary bladder. VIP- and GAL-positive nerve fibres were most numerous in the submucosa around blood vessels and in smooth muscle bundles of neovagina. They were distinctly less numerous beneath the epithelium. This innervation pattern mimicked that seen in normal vagina and in vaginal vestibule of patients with MRKHS. CONCLUSIONS Our findings demonstrate considerable nervous system plasticity in the bladder flap. Distribution of presumably sensory CGRP and PACAP immunoreactive nerve fibers was similar to the pattern observed within the intact bladder wall, and VIP or GAL immunoreactive nerve fibers (vasomotor functions) were distributed in a manner similar to that observed in the intact vaginal wall.

Abstract
Nerve growth factor (NGF), a neurotrophin required for the survival and maintenance of postganglionic sympathetic neurons, mediates its trophic effects by activation of its high-affinity receptor trkA. Null mutant mice lacking either NGF or trkA have profound sympathetic deficits, thus revealing the vital importance of NGF synthesis in target tissues and trkA expression by sympathetic neurons. In this study, we sought to assess whether sympathetic neurons of the superior cervical ganglion (SCG) display alterations in their neurochemical phenotype in adult mice carrying one mutated allele for either NGF or trkA, and whether such differences result in altered patterns of innervation to the submandibular salivary gland and pineal gland. In comparison with adult siblings, levels of trkA protein in the SCG were reduced in age-matched NGF(+/-) and trkA(+/-) mice. While NGF(+/-) mice also had significantly fewer sympathetic axons innervating both the submandibular salivary gland and pineal gland, densities of sympathetic axons in both tissues reached normal levels in trkA(+/-) mice. These findings reveal that while levels of trkA are reduced in SCG neurons of adult NGF(+/-) and trkA(+/-) mice (compared with their wild type counterparts), sympathetic axons are capable of achieving normal patterns of target innervation in trkA(+/-) mice but not in NGF(+/-) mice. As NGF protein levels are not depleted in the submandibular salivary gland and pineal gland of NGF(+/-) mice, a loss of sympathetic neurons [Nat Neurosci 1999; 2:699-705], in combination with reduced levels of trkA protein, may account for perturbed patterns of sympathetic innervation to peripheral tissues.

Abstract
We show that the BMP ortholog Gbb can signal by a retrograde mechanism to regulate synapse growth of the Drosophila neuromuscular junction (NMJ). gbb mutants have a reduced NMJ synapse size, decreased neurotransmitter release, and aberrant presynaptic ultrastructure. These defects are similar to those we observe in mutants of BMP receptors and Smad transcription factors. However, whereas these BMP receptors and signaling components are required in the presynaptic motoneuron, Gbb expression is required in large part in postsynaptic muscles; gbb expression in muscle rescues key aspects of the gbb mutant phenotype. Consistent with this notion, we find that blocking retrograde axonal transport by overexpression of dominant-negative p150/Glued in neurons inhibits BMP signaling in motoneurons. These experiments reveal that a muscle-derived BMP retrograde signal participates in coordinating neuromuscular synapse development and growth.

Abstract
Sympathetic axons in the upper eyelid and in tissues in the superior retro-orbital space were examined for NPY immunoreactivity. Sympathetic nerve terminals containing co-localised NPY were associated with blood vessels, the conjunctiva and the Meibomian glands. The acini of the Harderian gland completely lacked sympathetic innervation. Sympathetic axons lacking NPY were only found in the tarsal muscle. In addition, a minority of terminals, located in the more proximal part of the tarsal muscle, contained weak immunoreactivity to NPY. Injections of the retrograde tracer, Fast Blue, into the eyelid or retro-orbital space labelled postganglionic somata in the superior cervical ganglion. While many retrogradely labelled somata were immunoreactive for NPY, around half lacked NPY immunoreactivity and so are likely to project to the tarsal muscle. Most of the retrogradely labelled postganglionic somata lacking NPY were surrounded by terminals immunoreactive for met-enkephalin, leu-enkephalin and met-enkephalin arg-gly-leu which were all found to be present in the same nerve terminals. Sectioning the cervico-sympathetic trunk eliminated all enkephalin-immunoreactive pericellular baskets. Many enkephalin-immunoreactive pericellular terminals contained co-localised VAChT, calretinin and calbindin immunoreactivity, but completely lacked nitric oxide synthase immunoreactivity. A second population of nerve terminals that were immunoreactive for nitric oxide synthase also surrounded tarsal muscle-projecting neurons, but these terminals lacked immunoreactivity to enkephalin. Thus, postganglionic neurons projecting to the tarsal muscle are of at least two chemical phenotypes (with or without NPY) and they receive convergent input from at least two populations of preganglionic neurons with distinctive chemical phenotypes.

Abstract
The development of the nervous system entails the coordination of the spatial and chemical development of both pre- and postsynaptic elements. This coordination is accomplished by signals passing between neurons and the target cells that they innervate. This review focuses on well-characterized examples of target-mediated neuronal differentiation in the central and peripheral nervous systems. These include control of neurogenesis in the leech by male genitalia, presynaptic differentiation induced by postsynaptic molecules expressed by skeletal muscle, postsynaptic adhesion molecules that induce presynaptic differentiation in the central nervous system (CNS), target-mediated control of neurotransmitter phenotype in peripheral neurons, and target-regulated control of neuronal nicotinic acetylcholine receptors (nAChRs) and large conductance calcium-activated potassium channels (BK). The detailed understanding of these processes will uncover signals critical for the directed differentiation of stem cells as well as identify future targets for therapies in neural regeneration that promote the reestablishment of functional connections.

Abstract
Enteric neurons and glia arise from the neural crest. The phenotype of crest-derived cells was examined as they differentiated into neurons or glia in the mouse small and large intestine. Previous studies have shown that undifferentiated enteric crest-derived cells are Phox2b(+)/Ret(+)/p75(+)/Sox10(+), and at embryonic day (E) 10.5, about 10-15% of the crest-derived cells in the small intestine have started to differentiate into neurons. In the current study, by E12.5 and E14.5, about 25% and 47%, respectively, of Phox2b(+) cells in the small intestine were immunoreactive to the pan-neuronal protein, ubitquitin hydrolase (PGP9.5), and the percentage did not change dramatically from E14.5 onward. The differentiation of crest-derived cells into neurons in the colon lagged behind that in the small intestine by several days. Differentiating enteric neurons showed high Ret, low p75, and undetectable Sox10 immunostaining. Glial precursors were identified by the presence of brain-specific fatty acid binding protein (B-FABP) and detected first in the fore- and rostral midgut at E11.5. Glial precursors appeared to be B-FABP(+)/Sox10(+)/p75(+) but showed low Ret immunostaining. S100b was not detected until E14.5. Adult glial cells were B-FABP(+)/Sox10(+)/p75(+)/S100b(+). A nucleic acid stain (to identify all ganglion cells) was combined with immunostaining for PGP9.5 and S100b to detect neurons and glial cells, respectively, in the postnatal intestine. At postnatal day 0, fewer than 5% and 10% of cells in myenteric ganglia of the small and large intestine, respectively, were neither PGP9.5(+) nor S100b(+). Because some classes of neurons are not present in significant numbers until after birth, the expression of PGP9.5 by developing enteric neurons appeared to precede the expression of neuron type-specific markers.
