Trained Innate Immunity, Epigenetics, and Covid-19


Authors: Alberto Mantovani, M.D., and Mihai G. Netea, M.D. Innate immunity is mediated by different cell types and cell-associated or fluid-phase pattern-recognition molecules and plays a key role in tissue repair and resistance against pathogens.1 Exposure to selected vaccines, such as bacille Calmette–Guérin (BCG) or microbial components, can increase the baseline tone of innate immunity and trigger […]

Pre-existing immunity to SARS-CoV-2: the knowns and unknowns


Authors: Alessandro Sette 1 2, Shane Crotty 3 4 Abstract T cell reactivity against SARS-CoV-2 was observed in unexposed people; however, the source and clinical relevance of the reactivity remains unknown. It is speculated that this reflects T cell memory to circulating ‘common cold’ coronaviruses. It will be important to define specificities of these T cells and assess their association […]
