Possible mechanisms of Na+-induced release of calcium ions from the sarcoplasmic reticulum of skeletal muscle fibres of vertebrates


, : Possible mechanisms of Na+-induced release of calcium ions from the sarcoplasmic reticulum of skeletal muscle fibres of vertebrates. Fiziologicheskii Zhurnal (Kiev): 345: 60-66

The hypothesis of Na+-induced Ca2+ release from the sarcoplasmic reticulum (SR) of phasic skeletal muscle fibres of vertebrates is confirmed by the calculations of the .DELTA. Na+ change ra te outside the terminal cysterns of SR (TCSR) during the action potential generation. Two-stage mechanism of Ca2+ release from the SR is supposed. Initially transmembrane (T-system) Na+ influx causes small "depolarization-induced Ca2+ release" from the TCSR. These primarily released calcium ions become a trigger of the secondary main "Ca2+-induced Ca2+ release" from the SR. the physiological significance of the functional system of Na+ and Ca2+ involvement in the intracellular information transmission is discussed.
