Neuropeptide binding to a heart muscle cell, 3D fluorescence deconvolution micrograph. Stacked images showing calcitonin gene-related peptide (CGRP, red) binding to a binucleate cardiomyocyte. One of the cell's nuclei (white) can be seen along with myosin (blue) and actin (green) which make up the cell's contractile apparatus. Neuropeptides have been found to play a much larger role than initially thought in the control of calcium levels in organs other than the brain. Magnification: x900 when printed 10 centimetres wide.
