Diverse calcium channel types are present in the human placental syncytiotrophoblast basal membrane
(W B SAUNDERS CO LTD, 2006-12)
The functional expression of calcium channels has been scarcely studied in human placental syncytiotrophoblast. We have presently sought to characterize Ca2+ currents of the healthy syncytiotrophoblast basal membrane using ...
Sarcoplasmic reticulum release channels from frog skeletal muscle display two types of calcium dependence
(1993)
Calcium channels derived from sarcoplasmic reticulum of frog skeletal muscle were fused with planar lipid bilayers. Fractional open times displayed two types of calcium dependence: (i) blockable channels showed a bell-shaped ...
Calcium release modulated by inositol trisphosphate in ruptured fibers from frog skeletal muscle
(Springer-Verlag, 1990)
To investigate the effect of inositol 1,4,5-trisphosphate on calcium release, we used fiber bundles of frog sartorius muscle mechanically permeabilized by a scratching procedure, and we detected increments in calcium ...
High-Threshold Ca2+ channels behind gamma band activity in the pedunculopontine nucleus (PPN)
(American Physiological Society and The Physiological Society, 2015-07)
The pedunculopontine nucleus (PPN) is part of the Reticular Activating System, and active during waking and REM sleep. Previous results showed that all PPN cells plateau at gamma frequencies and intrinsic membrane oscillations ...
Calcium channel subtypes differentially regulate fusion pore stability and expansion
(2007)
Various studies have focused in the relative contribution of different voltage-activated Ca2+ channels (VACC) to total transmitter release. However, how Ca2+ entry through a given VACC subtype defines the pattern of ...
