Because of undeveloped T tubules and sparse sarcoplasmic reticulum, Ca(2+)-induced Ca(2+) release (CICR) may not be the major mechanism providing contractile Ca(2+) in the neonatal heart. Spatial association of dihydropyridine receptors (DHPRs) and ryanodine receptors (RyRs), a key factor for CICR, was examined in isolated neonatal rabbit ventricular(More)
The neonate mammalian heart is phenotypically different from the adult heart in many respects. Understanding these phenotypic differences are a fundamental component of understanding the mechanisms of congenital heart disease and its treatment. Differences in excitation-contraction (E-C) coupling of the neonatal heart from that of the adult include less(More)
Colocalization of dihydropyridine (DHPR) and ryanodine (RyR) receptors, a key determinant of Ca(2+)-induced Ca2+ release, was previously estimated in 3-, 6-, 10-, and 20-day-old rabbit ventricular myocytes by immunocytochemistry and confocal microscopy. We now report on the effects of deconvolution (using a maximum-likelihood estimation algorithm) on the(More)
