A Zinc‐ and Calcium‐Rich Lysosomal Nanoreactor Rescues Monocyte/Macrophage Dysfunction under Sepsis
Abstract: Sepsis is a dysregulation of the immune response to pathogens and has high morbidity and mortality worldwide. However, the unclear mapping and course of dysregulated immune cells currently hinders the development of advanced therapeutic strategies to treat sepsis. Here, evidence is provided using single‐cell RNA sequencing from peripheral blood mononuclear cells in sepsis that pathogens attacking monocytes/macrophages disrupt their immune function. The results reveal an enormous decline in monocytes/macrophages in sepsis and chart the evolution of their impaired phagocytosis (Pha) capabilities. Inspired by these findings, nanoparticles, named “Alpha‐MOFs,” are developed that target dysfunctional monocytes/macrophages to actively (A) lift (L) Pha by the release of lysosome‐sensitive ions from a mineralized metal–organic framework (MOF). Alpha‐MOFs have good stability and biosafety in peripheral blood and efficiently targeted monocytes/macrophages. They also release calcium and zinc ions into monocyte/macrophage lysosomes to promote the Pha and degradation of bacteria. Taken together, these results suggest that Alpha‐MOFs rescue monocytes/macrophages dysfunction and effectively improve their survival rate during sepsis.
