Due to the cancellation of the meeting “Immunity, Metabolism and Aging”, scheduled to take place in Modena (Italy), September 24-25 2020, for the difficult circumstances created by the global COVID-19 pandemic, we have suggested a "Symposium-in-Writing" whereby the speakers that have already accepted to give a talk in Modena will submit a paper to this special issue of the journal Immunity & Ageing.
