FRET-probe, 4mtd3cpv. Originally developed by Palmer and Tsien(75), this probe has been characterized for use in cardiac myocytes by Wüst et.al(80). Web15 de jun. de 2024 · As a first approximation, sensors inside the myocyte appear to modulate reactive oxygen species while sensors on the cell surface appear to also modulate nitric oxide signalling; both signalling pathways affect Ca 2+ handling. Undoubtedly, further studies will add layers to this simplified picture.
