We compared the cardiovascular effects of two structurally distinct L-type Ca++ channel activators, the 1,4-dihydropyridine Bay K 8644 and the benzoylpyrrole FPL 64176. Both compounds prolonged action potential duration and enhanced contractility in guinea pig papillary muscle with these responses
Estrogen-mediated neuroprotection is observed in neurodegenerative disease and neurotrauma models; however, determining a mechanism for these effects has been difficult. We propose that estrogen may limit cell death in the nervous system tissue by inhibiting increases in intracellular free Ca(2+).

Multiple voltage-gated Ca(2+) channel (Ca(V)) subtypes have been reported to participate in control of the juxtamedullary glomerular arterioles of the kidney. Using the patch-clamp technique, we examined whole cell Ca(V) currents of pericytes that contract descending vasa recta (DVR). The
To investigate the effect of increases in extracellular Ca(2+) entry produced by the L-type Ca(2+) channel agonist FPL-64176 (FPL) upon acute atrial arrhythmogenesis in intact Langendorff-perfused mouse hearts and its dependence upon diastolic Ca(2+) release from sarcoplasmic reticular Ca(2+) stores.
Recent studies suggest that iron enters cardiomyocytes via the L-type voltage-gated calcium channel (VGCC). The neuronal VGCC may also provide iron entry. As with calcium, extraneous iron is associated with the pathology and progression of neurodegenerative diseases such as Parkinson's
