Microglial HVCN1 Deficiency Improves Movement and Survival of SOD1G93A ALS Mice by Enhancing Microglial Migration and Neuroprotection

Advanced Science, EarlyView.
Hydrogen voltage gated channel 1 (HVCN1) is upregulated in microglia of both ALS patients and its mouse model. HVCN1 deficiency enhances microglial migration via suppressing Akt signaling, promotes neurotrophic capacity and motor function, and prolongs survival of the SOD1G93A ALS mice. This study identifies HVCN1 as a novel, promising druggable target

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 ...
