Innate immune cell and severe acute respiratory syndrome coronavirus 2 interaction

Coronavirus disease caused by the recently emerged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) represents a major public health that has submerged the world into a crisis unprecedented in the modern era. A better understanding of the innate immune response could help to fight this pandemic and be better prepared for potential future outbreaks. Interestingly, innate immune cells can develop a non-specific memory termed trained immunity. This review details recent evidence concerning the interaction of SARS-CoV-2 with innate immune cells, in particular those in which the trained immunity activity has been demonstrated.
