Persistent epigenetic memory of SARS-CoV-2 mRNA vaccination in monocyte-derived macrophages
25 Mar 2025
Abstract excerpt
Immune memory plays a critical role in the development of durable antimicrobial immune responses. How precisely mRNA vaccines train innate immune cells to shape protective host defense mechanisms remains unknown. Here we show that SARS-CoV-2 mRNA vaccination significantly establishes histone H3 lysine 27 acetylation (H3K27ac) at promoters of human monocyte-derived macrophages, suggesting epigenetic memory....
