Research Focus and Main research questions

The cyclic nucleotides (cAMP and cGMP) regulate cardiac function acting as second messengers for sympathetic and parasympathetic, nitric oxide (NO) and natriuretic peptide systems. Cyclic nucleotides may exert beneficial or deleterious effects on the heart, depending on the duration of the stimulation. Acute elevation of cyclic nucleotides regulates cardiac excitation-contraction coupling. Chronic elevation of cAMP contributes to the development of many cardiac diseases such as cardiac hypertrophy, heart failure and atrial fibrillation, while cGMP seems to covey mostly beneficial effects. The general objective of our laboratory is to understand the molecular mechanisms responsible for the homeostasis of these two second messengers and the functional consequences for cardiac function. By combining biochemical, molecular, genetic, electrophysiological and imaging techniques we aim to elucidate the mechanisms responsible for the temporal and spatial control of cyclic nucleotides signalling and their relevance to both physiological and disease conditions in animal models.

  • Recent Funding:

    Prof. Nikolaev and the Institute of Experimental Cardiovascular Research are funded by the Gertraud and Heinz Rose Foundation and several national and international grants.

    Our institute participates in the DFG research group 2060 “cGMP in cell growth and survival” with a subproject "cGMP microdomains in cardiomyocyte hypertrophy and heart failure". Moreover, we have subprojects in the newly funded Collaborative Research Center SFB1328 “Adenine nucleotides in immunity and inflammation” as well as in the European Research Area (ERANet) program called ERA-CVD.

    As part of the DZHK Hamburg/Kiel/Lübeck partner site, a scientific project entitled "Modulation of cAMP microdomains" is being purused. Its goal is the preclinical development of new therapeutic approached in the field of specific modulation of subcellular cAMP signals.
