Cytosolic DNA Sensing Promotes Macrophage Transformation and Governs Myocardial Ischemic Injury.

abstract：BACKGROUND:Optical mapping of cytosolic calcium transients in intact mammalian hearts is now possible using long-wavelength [Ca(2+)](i) indicators. We propose that beat-to-beat [Ca(2+)](i) transient alternans during ischemia may lead to spatial and temporal heterogeneity of calcium-activated membrane currents. METHODS...
