The epigenetic adaptation of innate immune cells to inflammatory stimuli, or trained immunity, represents an evolutionarily conserved feature of host defense. Recent advances have revealed that such adaptations can occur at the level of hematopoietic stem and progenitor cells, resulting in long-lasting epigenetic reprogramming of the immune system. However, a comprehensive mechanistic understanding of these processes remains incomplete, limiting our capacity to predict or therapeutically mani...
