Research Interest

Dr. Blatter's research group investigates control of intracellular calcium and its role in the regulation of excitation-contraction and excitation-transcription coupling in cells of the cardiovascular system.

Laboratory of Lothar A. Blatter

Cardiac Physiology. Study of mechanisms of excitation-contraction coupling and calcium regulation in cardiac (ventricular and atrial) muscle with the combined use of confocal imaging techniques and voltage clamp methods. Investigation of the regulation of cardiac ryanodine receptor calcium release channel incorporated into lipid bilayer. Investigation of the mechanism of cardiac alternans and cellular mechanisms of arrhythmias in cardiac hypertrophy and heart failure. Study of the role of IP3-dependent Ca signaling for excitation-contraction coupling, arrhythmias, and cardiac hypertrophy.

Laboratory of Lothar A. Blatter

Study of nuclear Ca signaling and regulation of translocation of transcription factor NFAT. Investigation of redox regulation of SR Ca release. Study of NO-dependent signaling pathways in cardiac cells. Study of oxidative stress and cardiac energy metabolism and its effects on excitation-contraction coupling and Ca signaling. Study of intracellular pH and measurement of intracellular [Na] with fluorescence 2-photon confocal microscopy. Study of the mechanism of pacemaker activity in cardiac cells.

Vascular Physiology. Investigation of cellular and molecular mechanisms of [Ca]i regulation in vascular endothelial cells with high temporal and spatial resolution, using digital video fluorescence microscopy and laser scanning confocal microscopy. Study of the spatio-temporal regulation of capacitative calcium entry in vascular endothelial cells. Investigation of cellular mechanisms of the regulation of nitric oxide (NO) production and release from vascular endothelial cells. Study of the role of NO for [Ca]i regulation in vascular endothelial cells. Ca-dependent regulation of translocation of transcription factor NFAT in vascular endothelial cells.

Mitochondria. Study of the mechanisms governing mitochondrial membrane potential, mitochondrial ion channels, and the role of mitochondria for cellular calcium homeostasis. Study of mitochondrial NO synthase function and regulation. These studies involve optical measurements of membrane potential, pH, calcium and sodium in single isolated mitochondria as well as in mitochondria in permeabilized and intact cells. The Seahorse flux analyzer is used to investigate mitocondrial respiration and metabolism.
