Studies have demonstrated the role of circulating endothelial progenitor cells (EPCs) in maintaining normal endothelial function and in endothelial repairing. This study was aimed to observe the protective effects of autologous transplantation of circulating EPCs against endotoxin-induced acute lung injury in rabbits and to investigate the underlying mechanisms. ⋯ Autologous transplantation of circulating EPCs can partly restore the pulmonary endothelial function and effectively attenuate endotoxin-induced acute lung injury by direct endothelial repair and indirect immunomodulation of antioxidation and antiinflammation.

Microglial inhibition may reduce secondary tissue injury and improve functional outcome following acute brain injury. Utilizing clinically relevant murine models of traumatic brain injury and intracerebral hemorrhage, neuroinflammatory responses and functional outcome were examined in the presence of a potential microglial inhibitor, TT-301. ⋯ Modulation of neuroinflammatory responses through TT-301 administration improved histologic and functional parameters in murine models of acute neurologic injury.
