Nonetheless, the role of this hypothalamic hormone and its receptor in the sensory pathway has yet to be fully explored. The present study performed immunohistochemistry, enzyme-linked immunosorbent assay, and RT-qPCR analysis to assess changes in the expression of the neuronal oxytocin receptor in female rats following tight ligation of the sciatic nerve after 1, 3, and 7 days of survival. Oxytocin receptor immunoreactivity was present in both dorsal root ganglia and lumbar spinal cord segments, but not accumulated at the site of the ligation of the peripheral nerve branch. We found a time-dependent change in the expression of oxytocin receptor mRNA in L5 dorsal root ganglion neurons, as well as an increase in the level of the receptor protein in the lumbar segment of the spinal cord. A peak in the expression was observed on day 3, which downturned slightly by day 7 after the nerve ligation. These results show that OTR expression is up-regulated in response to peripheral nerve lesions. We assume that the importance of OTR is to modify spinal presynaptic inputs of the sensory neurons upon injury-induced activation, thus to be targets of the descending oxytocinergic neurons from supraspinal levels. The findings of this study support the concept that oxytocin plays a role in somatosensory transmission.}, year = {2024}, eissn = {1422-0067} } @article{MTMT:31853713, title = {Exercise-mitigated sex-based differences in aging: From genetic alterations to heart performance}, url = {https://m2.mtmt.hu/api/publication/31853713}, author = {Börzsei, Denise and Priksz, Dániel and Szabó, Renáta and Bombicz, Mariann and Karácsonyi, Zoltán and Puskás, László and Fehér, Liliána Z. and Radák, Zsolt and Kupai, Krisztina and Magyariné, Berkó Anikó and Varga, Csaba and Juhász, Béla and Pósa, Anikó}, doi = {10.1152/ajpheart.00643.2020}, journal-iso = {AM J PHYSIOL HEART C}, journal = {AMERICAN JOURNAL OF PHYSIOLOGY: HEART AND CIRCULATORY PHYSIOLOGY}, volume = {320}, unique-id = {31853713}, issn = {0363-6135}, year = {2021}, eissn = {1522-1539}, pages = {H854-H866}, orcid-numbers = {Radák, Zsolt/0000-0003-1297-6804; Kupai, Krisztina/0000-0002-0644-1718; Magyariné, Berkó Anikó/0000-0002-1237-5745; Varga, Csaba/0000-0002-2678-665X; Pósa, Anikó/0000-0003-2167-2888} } @article{MTMT:3163480, title = {Nitroglycerin enhances the propagation of cortical spreading depression: Comparative studies with sumatriptan and novel kynurenic acid analogues}, url = {https://m2.mtmt.hu/api/publication/3163480}, author = {Knapp, Levente and Szita, B and Kocsis, Kitti and Vécsei, László and Toldi, József}, doi = {10.2147/DDDT.S117166}, journal-iso = {DRUG DES DEV THER}, journal = {DRUG DESIGN DEVELOPMENT AND THERAPY}, volume = {11}, unique-id = {3163480}, issn = {1177-8881}, abstract = {Background: The complex pathophysiology of migraine is not yet clearly understood; therefore, experimental models are essential for the investigation of the processes related to migraine headache, which include cortical spreading depression (CSD) and NO donor-induced neurovascular changes. Data on the assessment of drug efficacy in these models are often limited, which prompted us to investigate a novel combined migraine model in which an effective pharmacon could be more easily identified. Materials and methods: In vivo electrophysiological experiments were performed to investigate the effect of nitroglycerin (NTG) on CSD induced by KCl application. In addition, sumatriptan and newly synthesized neuroactive substances (analogues of the neuromodulator kynurenic acid [KYNA]) were also tested. Results: The basic parameters of CSDs were unchanged following NTG administration; however, propagation failure was decreased compared to the controls. Sumatriptan decreased the number of CSDs, whereas propagation failure was as minimal as in the NTG group. On the other hand, both of the KYNA analogues restored the ratio of propagation to the control level. Discussion: The ratio of propagation appeared to be the indicator of the effect of NTG. This is the first study providing direct evidence that NTG influences CSD; furthermore, we observed different effects of sumatriptan and KYNA analogues. Sumatriptan changed the generation of CSDs, whereas the analogues acted on the propagation of the waves. Our experimental design overlaps with a large spectrum of processes present in migraine pathophysiology, and it can be a useful experimental model for drug screening. © 2017 Knapp et al.}, keywords = {NITROGLYCERIN; MIGRAINE; SUMATRIPTAN; Cortical spreading depression; kynurenic acid analogues}, year = {2017}, pages = {27-34}, orcid-numbers = {Vécsei, László/0000-0001-8037-3672; Toldi, József/0000-0001-7355-0503} } @article{MTMT:3097684, title = {Acetyl-L-carnitine restores synaptic transmission and enhances the inducibility of stable LTP after oxygen–glucose deprivation}, url = {https://m2.mtmt.hu/api/publication/3097684}, author = {Kocsis, Kitti and Frank, Rita and Szabó, J and Knapp, Levente and Kis, Zsolt and Farkas, Tamás and Vécsei, László and Toldi, József}, doi = {10.1016/j.neuroscience.2016.06.046}, journal-iso = {NEUROSCIENCE}, journal = {NEUROSCIENCE}, volume = {332}, unique-id = {3097684}, issn = {0306-4522}, abstract = {Hypoxic circumstances result in functional and structural impairments of the brain. Oxygen–glucose deprivation (OGD) on hippocampal slices is a technique widely used to investigate the consequences of ischemic stroke and the potential neuroprotective effects of different drugs. Acetyl-L-carnitine (ALC) is a naturally occurring substance in the body, and it can therefore be administered safely even in relatively high doses. In previous experiments, ALC pretreatment proved to be effective against global hypoperfusion. In the present study, we investigated whether ALC can be protective in an OGD model. We are not aware of any earlier study in which the long-term potentiation (LTP) function on hippocampal slices was measured after OGD. Therefore, we set out to determine whether an effective ALC concentration has an effect on synaptic plasticity after OGD in the hippocampal CA1 subfield of rats. A further aim was to investigate the mechanism underlying the protective effect of this compound. The experiments revealed that ALC is neuroprotective against OGD in a dose-dependent manner, which is manifested not only in the regeneration of the impaired synaptic transmission after the OGD, but also in the inducibility and stability of the LTP. In the case of the most effective concentration of ALC (500 μM), use of a phosphoinositide 3-kinase (PI3K) inhibitor (LY294002) revealed that the PI3K/Akt signaling pathway has a key role in the restoration of the synaptic transmission and plasticity reached by ALC treatment. © 2016 IBRO}, keywords = {ISCHEMIA; LONG-TERM POTENTIATION; neuroprotection; oxygen-glucose deprivation; ACETYL-L-CARNITINE; PI3K/Akt}, year = {2016}, eissn = {1873-7544}, pages = {203-211}, orcid-numbers = {Kis, Zsolt/0000-0002-6896-5883; Vécsei, László/0000-0001-8037-3672; Toldi, József/0000-0001-7355-0503} } @article{MTMT:3085614, title = {Routing of olfactory inputs to the brainstem raphé nucleus}, url = {https://m2.mtmt.hu/api/publication/3085614}, author = {Furdan, Szabina and Lőrincz, László Magor}, doi = {10.1016/j.clinph.2015.11.417}, journal-iso = {CLIN NEUROPHYSIOL}, journal = {CLINICAL NEUROPHYSIOLOGY}, volume = {127}, unique-id = {3085614}, issn = {1388-2457}, year = {2016}, eissn = {1872-8952} } @misc{MTMT:3080759, title = {Gyulladásos és keringési paraméterek vizsgálata ösztrogénhiányos patkány modellekben}, url = {https://m2.mtmt.hu/api/publication/3080759}, author = {Szabó, Renáta}, unique-id = {3080759}, year = {2016} } @misc{MTMT:3080751, title = {The effects of aging and experimental menopause on the cardiac and inflammatory parameters}, url = {https://m2.mtmt.hu/api/publication/3080751}, author = {Szabó, Renáta and Csonka, Anett and Veszelka, Médea and Kupai, Krisztina and Magyariné, Berkó Anikó and Deim, Zoltán and Baráth, Zoltán Lajos and Ménesi, Rudolf and Pávó, Imre and Gyöngyösi, Mariann and László, Ferenc and Varga, Csaba and Pósa, Anikó}, unique-id = {3080751}, year = {2016}, orcid-numbers = {Kupai, Krisztina/0000-0002-0644-1718; Magyariné, Berkó Anikó/0000-0002-1237-5745; Deim, Zoltán/0000-0003-3925-5564; Baráth, Zoltán Lajos/0000-0003-0636-6313; Varga, Csaba/0000-0002-2678-665X; Pósa, Anikó/0000-0003-2167-2888} } @misc{MTMT:3080732, title = {Metabolikus, gyulladásos és kardiovaszkuláris eltérések vizsgálata ösztrogénhiányos állapotokban}, url = {https://m2.mtmt.hu/api/publication/3080732}, author = {Szabó, Renáta and Veszelka, Médea and Csonka, Anett and Kupai, Krisztina and Börzsei, Denise and Szűcs, Gergő and Török, Szilvia and Amin, Al-Awar and Magyariné, Berkó Anikó and Varga, Csaba and Pósa, Anikó}, unique-id = {3080732}, year = {2016}, orcid-numbers = {Kupai, Krisztina/0000-0002-0644-1718; Szűcs, Gergő/0000-0003-1874-2718; Magyariné, Berkó Anikó/0000-0002-1237-5745; Varga, Csaba/0000-0002-2678-665X; Pósa, Anikó/0000-0003-2167-2888} } @mastersthesis{MTMT:33401913, title = {A szelektív ösztrogén receptor modulátorok által közvetített protektív mechanizmusok}, url = {https://m2.mtmt.hu/api/publication/33401913}, author = {Pósa, Anikó}, publisher = {SZTE}, unique-id = {33401913}, year = {2015}, orcid-numbers = {Pósa, Anikó/0000-0003-2167-2888} }
