Cellular Mechanism of Nicotine-mediated Intracellular Calcium Homeostasis in Primary Culture of Mouse Cerebellar Granule Cells
김원기(Won-Ki Kim), 배영숙(Young-Sook Pae) 대한약리학회 대한약리학잡지 10 Pages
대한약리학회 대한약리학잡지 1996, 제 32권 제 1호 2 13-22 (10 pages)
a variety of neuronal functions. Here we report that in primary culture of mouse cerebellar granule cells nicotinic acetylcholine receptors (nAChRs) are expressed in a specific developmental stage and involved in the regulation of intracellular calcium homeostasis. Nicotine-mediated calcium responses were measured using 45Ca2+ or fluorometrically using the calcium-sensitive fluorescent dye fura-2. Maximal uptake of 45Ca2+ evoked by nicotine in mouse cerebellar granule cells were revealed 8 ~ 12... -

흰쥐 소뇌로부터 과립신경세포를 배양하여 NaCN으로 유도되는 신경세포손상에 대한 ginsenosides의 보호효과를 검토하였다. NaCN(I~10 M)을 배양된 세포에 1시간 동안 처리하면 농도 의존적으로 신경세포사를 일으켰다. Ginsenosides(Rb$_1$, Rc, Re, Ri, Rg$_1$)(0.5, 5 $mu extrm{g}$/ml를 세포에 전처치하면 10 mM NaCN으로 유도되는 세포사가 현저히 감소되었다. Rb$_1$과 Rc(5$mu extrm{g}$/ml)는 5 mM NaCN에 의하여 배양액 중으로 유리되는 glutamate의 증가를 현저히 억제하였으며, 1 mM N3CN에 의하여 유발되는 세포내... -
Effects of Treadmill Exercise on the Recovery of Dopaminergic Neuron Loss and Muscle Atrophy in the 6-OHDA Lesioned Parkinson's Disease Rat Model

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2012, Vol.16 No.5 3 305-312 (8 pages)
This study was to determine the effect of exercise on the recovery of dopaminergic neuron loss and muscle atrophy in 6-OHDA-induced hemi Parkinson's disease model. Exercise was loaded twice per day for 30 minutes each time, at 5 days after 6-OHDA lesioning and continued for 16 days using a treadmill. Exercise significantly increased the number of tyrosine hydroxylase positive neuron in the lesioned substantia nigra and the expression level of tyrosine hydroxylase in the striatum compared with... -
Zn2+ Modulates the Responses of Rat Dorsal Horn Neuron to C-Fiber Stimulation and Excitatory Amino Acids

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2000, Vol.4 No.6 3 445-453 (9 pages)
Zinc contained in the neurons of central nervous system is activity-dependently released and then attenuates NMDA (N-methyl-D-aspartate)-induced neurotoxicity while augmenting non-NMDA-induced neurodegeneration. Zinc also has been reported to produce antinociceptive action on the inflammation- and nerve injury-induced hyperalgesia in the behavioral test. In this study, we investigated the effects of zinc on the responses of dorsal horn cells to NMDA, kainate and graded electrical stimulation of... -
Immunohistochemistry of Voltage-Gated Calcium Channel α1B Subunit in Mouse Cerebellum
Seung-Hyuk Chung, Kyung-Youl Lee, Ki-Hyung Kim, Chul-Tae Kim, Nam-Seob Lee, Kazuhiko Sawada, Hiromi Haga, Byung-Chul Lee, Yoshih 대한수의학회 Journal of Veterinary Science 4 Pages

Secretion of neurotransmitters is initiated by voltage-gated calcium influx through presynaptic, voltage- gated N-type calcium channels. However, little is known about their cellular distribution in the mouse cerebellum. In the cerebellum, alpha1B immunoreactivity is found mainly on the cell bodies of all Purkinje cells. In addition, the immunoreactivity was detected on a subset of Purkinje cell dendrites, clustered to form a parasagittal array of bands. In the anterior lobe vermis,... -
DAMGO modulates two-pore domain K+ channels in the substantia gelatinosa neurons of rat spinal cord

The analgesic mechanism of opioids is known to decrease the excitability of substantia gelatinosa (SG) neurons receiving the synaptic inputs from primary nociceptive afferent fiber by increasing inwardly rectifying K+ current. In this study, we examined whether a μ-opioid agonist, [D-Ala2,N-Me-Phe4, Gly5-ol]-enkephalin (DAMGO), affects the two-pore domain K+ channel (K2P) current in rat SG neurons using a slice whole-cell patch clamp technique. Also we confirmed which subtypes of K2P channels... -
Preventive effects of imperatorin on perfluorohexanesulfonate-induced neuronal apoptosis via inhibition of intracellular calcium-mediated ERK pathway

pharmacological effects including neuroprotection. In this study, the effects of imperatorin on PFHxS-induced neuronal apoptosis and the underlying mechanisms are examined using cerebellar granule cells (CGC). CGC were isolated from seven-day old rats and were grown in culture for seven days. Caspase-3 activity and TUNEL staining were used to determine neuronal apoptosis. PFHxS-induced apoptosis of CGC was significantly reduced by imperatorin and PD98059, an ERK pathway inhibitor. PFHxS induced... -

Many intracellular proteins and signaling cascades contribute to the sensitivity of N-methyl-D- aspartate receptors (NMDARs). One such putative contributor is the serine/threonine kinase, protein kinase C (PKC). Activation of PKC by phorbol 12-myristate 13-acetate (PMA) causes activation of extracellular signal-regulated kinase (ERK) and promotes the formation of new spines in cultured hippocampal neurons. The purpose of this study was to examine which PKC isoforms are responsible for the...
