A Conjugation Delivery System of Macrophages and Platelet Pharmacytes Promotes Regeneration After Spinal Cord Injury

Advanced Science, EarlyView.
A macrophage–platelet conjugation system (M‐P‐NPs@PPARγ) targets injure tissue to co‐deliver platelet mitochondria and PPARγ‐encoding NPs. This strategy boosts the macrophage energy supply and restores lipid homeostasis, leading to synergistically enhanced efferocytosis and tissue repair Abstract Mitochondrial dysfunction occurs in macrophages with ...

Single‐Cell Profiling Across Immune Tissues and Organs Reveals Immunosenescence Signatures in Male Rhesus Monkeys

Advanced Science, EarlyView.
Single‐cell profiling across bone marrow, spleen, mesenteric lymph, and blood in rhesus monkeys reveals organ Immunosenescence. GZMB rises with age, particularly in cytotoxic and terminally exhausted CD8+ T cells, and BHLHE40 emerges as a key transcription factor enriched across multiple CD8+ subsets, regulating pro‐inflammatory and exhaustion‐related ...
