BCR-induced Ca2＋ signaling. CD40 co-stimulation also enhanced BCR internalization and reduced expression of PLCՃ2 and IP3R-3. Pre-treatment of WEHI-231 cells with the antioxidant N-acetyl-L-cysteine (NAC) strongly inhibited CD40-mediated prevention of the recovery of Ca2＋ signaling. In contrast to immature WEHI-231 cells, identical long-term Ձ-IgM pre-stimulation of mature Bal-17 cells abolished the increase in BCR-induced [Ca2＋]i, regardless of CD40 co-stimulation. These results...

augmented the frequency of the spontaneous contractions. The cumulative application of NE also augmented the frequency in a dose-dependent manner. The effects of NE application were inhibited by concomitant application of 10−5 M glibenclamide. Receptor tyrosine kinase (c-kit) staining revealed abundant ICCs only in proximal tissues. Therefore, spontaneous contractions of the human ureter might be modulated by ICC in the proximal region, and the actions might be related with the activation...

Many therapeutic roles have been proposed for sigma-1 receptor (Sig-1R), but the involvement of Sig-1R in neuropathic pain has currently not been well explored. The present study aimed to evaluate the anti-nociceptive effect of Sig-1R antagonist (BD1047) in a rat model of chronic compression of the dorsal root ganglion (CCD), which is a model of human foraminal stenosis and radicular pain. When stainless steel rods were inserted into the intervertebral foramen of lumbar vertebrae 4 and 5, the...

a non-selective P2 receptor antagonist, reduced the contraction induced by EFS. NF023 (10−7∼10−4 M), a selective P2X antagonist, inhibited the contraction evoked by EFS. Reactive blue (10−6∼10−4 M), selective P2Y antagonist, also blocked the contraction in a dose-dependent manner. In addition, P2X agonist Ձ,Ղ-methylene 5'-adenosine triphosphate (ՁՂMeATP, 10−7∼10−5 M) potentiated EFS-induced contrac</SUP>tion in a dose-dependent...

Inositol 1,4,5-trisphosphate receptors (InsP3Rs) modulate Ca2＋ release from intracellular Ca2＋ store and are extensively expressed in the membrane of endoplasmic/sarcoplasmic reticulum and Golgi. Although caffeine and 2-aminoethoxydiphenyl borate (2-APB) have been widely used to block InsP3Rs, the use of these is limited due to their multiple actions. In the present study, we examined and compared the ability of caffeine and 2-APB as a blocker of Ca2＋ release from intracellular Ca2＋ stores...

(a cytoplasmic Ca2＋-ATPase inhibitor, 10ՌM) were significantly reduced, respectively. In the simultaneous presence of PCRC (60Ռg/ml) and L-NAME (an inhibitor of NO synthase, 30ՌM), the inhibitory responses of PCRC on the CA secretion evoked by ACh, high K＋, DMPP, and Bay-K-8644 were considerably recovered to the extent of the corresponding control secretion compared with that of PCRC-treatment alone. The level of NO released from adrenal medulla after the treatment of PCRC...

Induced activation of the gamma-aminobutyric acidA (GABAA) receptor in the retina of goldfish caused the fish to rotate in the opposite direction to that of the spinning pattern during an optomotor response (OMR) measurement. Muscimol, a GABAA receptor agonist, modified OMR in a concentration- dependent manner. The GABAB receptor agonist baclofen and GABAC receptor agonist CACA did not affect OMR. The observed modifications in OMR included decreased anterograde rotation...

terminals. GABAergic spontaneous inhibitory postsynaptic currents (sIPSCs) in the A1 were completely blocked by bicuculline. The NO donor, S-nitroso-N-acetylpenicillamine (SNAP), reduced the GABAergic sIPSC frequency without affecting the mean current amplitude. The SNAP- induced inhibition of sIPSC frequency was mimicked by 8-bromoguanosine cyclic 3',5'-monophosphate, a membrane permeable cyclic-GMP analogue, and blocked by 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, a...

RGC firing rates while increasing the pulse frequency from 1 to 10 pulses per second (or Hz) to deduce the optimal pulse frequency range for modulation of RGC response strength. RGC response strength monotonically and linearly increased within the stimulation frequency of 1∼9 Hz. The results suggest that the evoked neural activities of RGCs in degenerated retina can be reliably controlled by pulse frequency modulation, and may be used as a stimulation strategy for visual neural prosthesis.

NO released by myenteric neurons controls the off contraction induced by electrical field stimulation (EFS) in distal esophageal smooth muscle, but in the presence of nitric oxide synthase (NOS) inhibitor, L-NAME, contraction by EFS occurs at the same time. The authors investigated the intracellular signaling pathways related with G protein and ionic channel EFS-induced contraction using cat esophageal muscles. EFS-induced contractions were significantly suppressed by tetrodotoxin (1ՌM)...
