Paradoxical SR Ca(2+) release in guinea-pig cardiac myocytes after β-adrenergic stimulation revealed by two-photon photolysis of caged Ca(2+)
In heart muscle the amplification and shaping of Ca(2+) signals governing contraction are orchestrated by recruiting a variable number of Ca(2+) sparks. Sparks reflect Ca(2+) release from the sarcoplasmic reticulum (SR) via Ca(2+) release channels (ryanodine receptors, RyRs). RyRs are activated by C...
