This study investigates the role of lysosomal Ca2+ signaling in heart rhythm and atrial function, finding that NAADP pathway inhibition affects SAN pacemaker activity and cAMP production in atrial myocytes.

This study shows TPC2 activation enhances lysosome-mitochondria calcium transfer, affecting mitochondrial function and stress responses, with implications for neuroprotection in stroke.

This study shows that IP3R activation in atrial myocytes increases cAMP, which can be inhibited by IP3R blockers, but ventricular myocytes show cAMP increases independent of IP3R.
