Cím:Development of calbindin-D28k immunoreactive neurons in the embryonic chick lumbosacral spinal cord / Miklós Antal, Erika Polgár
Dátum:1993
Megjegyzések:The development of immunoreactivity for the calcium-binding protein calbindin-D28k (CaB) was investigated in the embryonic and hatched chick lumbosacral spinal cord. CaB-immunoreactive neurons were revealed in the dorsal and ventral horns as well as in the intermediate grey matter from early stages of neuronal development. CaB immunoreactivity was first detected in large neurons in the presumptive dorsal horn at embryonic day 5, while small neurons in the lateral dorsal horn were the last to appear, at embryonic day 10. We have identified and traced the morphological maturation of six CaB-immunoreactive cell groups, three in the dorsal horn and three in the ventral horn. In the dorsal horn these groups were (1) large neurons in the lateral dorsal horn (laminae I and IV), (2) small neurons in the lateral dorsal horn (lamina II), and (3) small neurons in the medial dorsal horn (lamina III). All three groups were present throughout the entire length of the lumbosacral spinal cord and showed persistent CaB immunoreactivity. In the ventral horn, CaB-immunoreactive neurons were classified into the following three categories: (1) Neurons dorsal to the lateral motor column (lamina VII). These neurons were present exclusively in the upper lumbosacral segments (LS1-3), and they showed steady CaB immunoreactivity during their maturation. (2) Neurons at the dorsomedial aspect of the lateral motor column (at the border of laminae VII and IX). This population of neurons was characteristic of the lower segments of the lumbosacral cord (LS5-7) and presented transient CaB expression. (3) Neurons within the lateral motor column (lamina IX). These neurons were dispersed throughout the length of the lumbosacral spinal cord. They were three to four times more numerous in the upper than in the lower lumbosacral segments, and their numbers declined throughout LS1-7 as the animal matured. The characteristic features of the development of neurons immunoreactive for CaB are discussed and correlated with previous neuroanatomical and physiological studies concerning sensory and motor functions of the developing chick spinal cord.

Cím:Expression of hyperpolarization-activated and cyclic nucleotide-gated cation channel subunit 2 in axon terminals of peptidergic nociceptive primary sensory neurons in the superficial spinal dorsal horn of rats / Antal, M., Papp, I., Bahaerguli, N., Veress, G., Vereb, G.
Dátum:2004
Megjegyzések:Hyperpolarization-activated cyclic nucleotide-gated cation channel proteins (HCN1-4), which are potentially able to modulate membrane excitability, are abundantly expressed by neurons in spinal dorsal root ganglia (DRG). In the present experiment, we investigated whether HCN2 protein is confined exclusively to the perikarya of DRG neurons or is transported from the somata to the central axons of DRG neurons that terminate in the spinal dorsal horn. Using immunohistochemical methods, we have demonstrated that laminae I-IIo of the superficial spinal dorsal horn of the adult rat spinal cord show a strong punctate immunoreactivity for HCN2. Dorsal rhizotomy resulted in a complete loss of immunostaining in the dorsal horn, suggesting that HCN2 is confined to axon terminals of primary afferents. In double labelling immunohistochemical studies, we have also shown that HCN2 widely co-localizes with calcitonin gene-related peptide, but is almost completely segregated from isolectin-B4 binding, indicating that HCN2 is primarily expressed in peptidergic nociceptive primary afferents. The expression of HCN2 in central terminals of peptidergic primary afferents was also verified with electron microscopy. Utilizing the pre-embedding nanogold method, we found that HCN2 is largely confined to axon terminals with dense-core vesicles. Within these terminals, some of the silver grains marking the accurate location of HCN2 molecules were associated with the cell membrane, and others were scattered in the axoplasm. Within the cell membrane, HCN2 was found almost exclusively in extrasynaptic locations. The results suggest that HCN2 may contribute to the modulation of membrane excitability of nociceptive primary afferent terminals in the spinal dorsal horn.

Cím:The application of cobalt labelling to electron microscopic investigations of serial sections / Antal M.
Dátum:1984
ISSN:0165-0270
Megjegyzések:The cobalt labelling technique can be applied to ultrathin serial sections and subsequent electron microscopical investigations with the following modifications: a prolonged, up to 12 h, fixation of the tissue in aldehydes; a shortened, 15 min, postfixation in OsO4; embedding in soft resin block by using a higher proportion of plasticizer in the polimerizing mixture; mounting of 5 micrometers thick serial sections between two layers of Agar-Agar coatings; performing the intensification of the Agar section-Agar sandwich with a physical developer containing a low percentage of the reductive agent; reembedding selected thick sections for ultrathin serial sectioning and staining with uranile acetate and lead citrate. The technique unambiguously shows all labelled profiles, and preserves the fine structural details of the surrounding tissues.

Cím:The extent of the dendritic tree and the number of synapses in the frog motoneuron / Birinyi A., Antal M., Wolf E., Székely G.
Dátum:1992
ISSN:0953-816X
Megjegyzések:Frog motoneurons were intracellularly labelled with cobaltic lysine in the brachial and the lumbar segments of the spinal cord, and the material was processed for light microscopy in serial sections. With the aid of the neuron reconstruction system NEUTRACE, the dendritic tree of neurons was reconstructed and the length and surface area of dendrites measured. The surface of somata was determined with the prolate - oblate average ellipsoid calculation. Corrections were made for shrinkage and for optical distortion. The mean surface area of somata was 6710 microm2; lumbar motoneurons were slightly larger than brachial motoneurons. The mean length of the combined dendritic tree of brachial neurons was 29 408 microm and that of lumbar neurons 46 806 microm. The mean surface area was 127 335 microm2 in brachial neurons, and 168 063 microm2 in lumbar neurons. The soma - dendrite surface area ratio was 3 - 5% in most cases. Dendrites with a diameter of </= 1.0 microm constituted approximately 75% of the combined dendritic length in most of the neurons. Unlike in the cat, there was no correlation between the size of stem dendrites and the extent of daughter branches. From the synaptic density estimated in earlier electron microscope investigations of frog motoneuron dendrites (Antal et al., J. Neurocytol., 15, 303 - 310, 1986; 21, 34 - 49, 1992), and from the present data, the number of synapses on the dendritic tree was calculated. The calculations indicated 26 949 synapses on the smallest and 61 519 synapses on the largest neuron if the synaptic density was multiplied by the length of the dendritic tree. If the synaptic density was multiplied by the surface area of the dendritic tree the calculation yielded 23 337 synapses for the smallest and 60 682 synapses for the largest neuron. More than 60% of the combined surface area of dendrites was >600 microm from the soma. This suggests that about two-thirds of the synapses impinged upon distant dendrites >600 microm from the soma. The efficacy of synapses at these large distances is investigated on model neurons in the accompanying paper

Cím:The projections of the midbrain periaqueductal gray to the pons and medulla oblongata in rats / Odeh F., Antal M.
Dátum:2001
Megjegyzések:It is now established that stimulation of the ventrolateral midbrain periaqueductal grey (PAG) evokes inhibition of nociceptive spinal neurons, which results in analgesia and a powerful attenuation of pain behaviour. It is postulated that the PAG exerts this inhibitory effect on spinal nociceptive functions through the activation of descending serotonergic and noradrenergic pathways that arise from the rostral ventromedial medulla (RVM) and pontine noradrenergic nuclei. To investigate the neuroanatomical substrate of this functional link between the PAG and RVM, as well as the pontine noradrenergic nuclei in the rat, we labelled axons that project from the ventrolateral PAG to various regions of the pons and medulla oblongata using the anterograde tracing substance, Phaseolus vulgaris leucoagglutinin. We demonstrated that some of PAG efferents really do terminate in the RVM and pontine noradrenergic nuclei, but a substantial proportion of them project to the intermediate subdivision of the pontobulbar reticular formation. Combining the axonal tracing with serotonin- and tyrosine-hydroxylase-immunohistochemistry, we also found that, in contrast to previous results, PAG efferents make relatively few appositions with serotonin- and tyrosine-hydroxylase-immunoreactive neurons in the RVM and pontine noradrenergic nuclei; most of them terminate in nonimmunoreactive territories. The results suggest that the ventrolateral PAG may activate a complex pontobulbar neuronal assembly including neurons in the intermediate subdivision of the pontobulbar reticular formation, serotonin- and tyrosine-hydroxylase-immunoreactive and nonimmunoreactive neurons in the RVM and pontine noradrenergic nuclei. This pontobulbar neural circuitry, then, may mediate the PAG-evoked activities towards the spinal dorsal horn resulting in the inhibition of spinal nociceptive functions.

Cím:Neurons with distinctive firing patterns, morphology and distribution in laminae V-VII of the neonatal rat lumbar spinal cord / Szűcs P., Odeh F., Szokol K., Antal M.
Dátum:2003
Megjegyzések:It is generally accepted that neurons in the ventral spinal grey matter, a substantial proportion of which can be regarded as constituents of the spinal motor apparatus, receive and integrate synaptic inputs arising from various peripheral, spinal and supraspinal sources. Thus, a profound knowledge concerning the integrative properties of interneurons in the spinal ventral grey matter appears to be essential for a fair understanding of operational principles of spinal motor neural assemblies. Using the whole cell patch clamp configuration in a correlative physiological and morphological experimental approach, here we demonstrate that the intrinsic membrane properties of neurons vary widely in laminae V-VII of the ventral grey matter of the neonatal rat lumbar spinal cord. Based on their firing patterns in response to depolarizing current steps, we have classified the recorded neurons into four categories: 'phasic', 'repetitive', 'single' and 'slow'. Neurons with firing properties characteristic of the 'phasic', 'repetitive' and 'single' cells have previously been reported also in the superficial and deep spinal dorsal horn, but this is the first account in the literature in which 'slow' neurons have been recovered and described in the spinal cord. The physiological heterogeneity in conjunction with the morphological correlation and distribution of neurons argues that different components of motor neural assemblies in the spinal ventral grey matter possess different signal processing characteristics.

Cím:Protective Effect of Alpha-Melanocyte-Stimulating Hormone (α-MSH) on the Recovery of Ischemia/Reperfusion (I/R)-Induced Retinal Damage in A Rat Model / Balazs Varga, Rudolf Gesztelyi, Mariann Bombicz, David Haines, Adrienn Monika Szabo, Adam Kemeny-Beke, Miklos Antal, Miklos Vecsernyes, Bela Juhasz, Arpad Tosaki
Dátum:2013
ISSN:0895-8696
Megjegyzések:The present study demonstrates capacity of α-MSH to augment recovery from ischemia/reperfusion (I/R)-induced retinal damage in vivo and correlation of its protective effects with expression of heme oxygenase-1 (HO-1). Used techniques include ocular ischemia and reperfusion, electroretinography, histology, electron microscopy, and molecular-biological techniques. The results demonstrate the α-MSH-mediated inhibition of I/R-induced functional deterioration of the retina. Outcomes suggest that the protective effects of α-MSH occur mainly through HO-1-dependent pathways but HO-1-independent mechanisms may also contribute to protection. The observation that post-ischemic treatment with α-MSH exhibits therapeutic efficacy in the same range as pre-ischemic treatment, is a novel result. This outcome suggests a highly conserved protective role for α-MSH as a major stress response mechanism-and offers the possibility for development of novel therapeutic strategies utilizing this hormone, in particular in treatment of conditions resulting from I/R injury, such as deterioration of retinal microcirculation. The merit of the study lies in the fact that I/R injury contribute significantly to the severity of retinopathies. However, currently there are no evidence-based treatments for retinal I/R injury available for clinical use. Our finding suggests that α-MSH may have a very wide range of uses in the prevention of I/R-mediated pathologies.
