Nature CommunicationsAbstract
Contacts between mitochondria and endoplasmatic reticulum (ER), and the transfer of calcium between them, have an important role in the regulation of cellular phenotypes, including senescence. Here the authors show that ITPR2 deficient mice display improved aging, associated with a decreased number of contacts between the mitochondria and the ER
