Exocytotic release of ATP and activation of P2X receptors in dissociated guinea pig stellate neuronsJohn D Tompkins
University of Vermont, College of Medicine, Dept of Anatomy and Neurobiology, Burlington, VT 05405, USA
Am J Physiol Cell Physiol 291:C1062-71. 2006..These results suggest that ASTICs are mediated by vesicular release of ATP and activation of P2X receptors...
Identification of intracellular signaling cascades mediating the PACAP-induced increase in guinea pig cardiac neuron excitabilityJohn D Tompkins
Department of Anatomy and Neurobiology, College of Medicine, University of Vermont, Burlington, VT 05405, USA
J Mol Neurosci 36:292-8. 2008..We conclude that the activation of signaling cascades downstream of cAMP mediate the PACAP-induced increase in cardiac neuron excitability...
VIP and PACAP effects on mouse major pelvic ganglia neuronsJohn D Tompkins
Departments of Anatomy and Neurobiology, College of Medicine, University of Vermont, Burlington, VT 05405, USA
J Mol Neurosci 42:390-6. 2010..The results suggest that VIP has a role in the neural control of pelvic organ function and activation of VPAC and/or PAC1 receptors can modulate the activity of the autonomic neurons innervating pelvic organs...
Ca2+ influx, but not Ca2+ release from internal stores, is required for the PACAP-induced increase in excitability in guinea pig intracardiac neuronsJohn D Tompkins
Department of Anatomy and Neurobiology, University of Vermont, Burlington, VT 05405, USA
J Neurophysiol 95:2134-42. 2006....
Enhancement of Ih, but not inhibition of IM, is a key mechanism underlying the PACAP-induced increase in excitability of guinea pig intrinsic cardiac neuronsJohn D Tompkins
Department of Anatomy and Neurobiology, College of Medicine, University of Vermont, Burlington, Vermont 05405, USA
Am J Physiol Regul Integr Comp Physiol 297:R52-9. 2009....
Neurally released pituitary adenylate cyclase-activating polypeptide enhances guinea pig intrinsic cardiac neurone excitabilityJohn D Tompkins
Department of Anatomy and Neurobiology, College of Medicine, University of Vermont, Burlington, VT 05405, USA
J Physiol 582:87-93. 2007..We hypothesize that in vivo PACAP released during preganglionic firing may modulate neurotransmission within the intrinsic cardiac ganglia...
Calcium-induced calcium release regulates action potential generation in guinea-pig sympathetic neuronesSarah A Locknar
Department of Anatomy and Neurobiology, University of Vermont College of Medicine, Burlington, VT 05405, USA
J Physiol 555:627-35. 2004....
Calcium influx through channels other than voltage-dependent calcium channels is critical to the pituitary adenylate cyclase-activating polypeptide-induced increase in excitability in guinea pig cardiac neuronsJean C Hardwick
Department of Biology, Ithaca College, Ithaca, NY 14850, USA
Ann N Y Acad Sci 1070:317-21. 2006..Exposure to a Ca2+-deficient solution did not deplete [Ca2+]i stores but did eliminate the PACAP-induced increase in excitability. We postulate that Ca2+ influx is required for the PACAP-induced increase in excitability...
Electrophysiological effects of tachykinin agonists on sympathetic ganglia of spontaneously hypertensive ratsJohn D Tompkins
Department of Pharmacology, James H. Quillen College of Medicine, East Tennessee State University, Johnson City 37614-1708, USA
Auton Neurosci 97:26-34. 2002..In conclusion, SHRs are more responsive to ganglion stimulation by NK1 agonists due to a greater number of responsive cells within the SCG rather than an enhanced responsiveness of individual neurons...
