Sea Buckthorn Oil Promotes the PI3K-Akt-ERK Signaling Pathway and Macrophage M2 Polarization to Reduce Radiation-induced Skin Injury.

In this work, we explored the role and mechanism of sea buckthorn oil in reducing radiation-induced skin damage. The radiation-induced rat skin injury model was established using strontium-90. Rats were treated with sea buckthorn oil twice a day postirradiation, and skin damage was observed at different times and evaluated using an injury score.

CD28 deficiency attenuates primary blast-induced renal injury in mice via the PI3K/Akt signalling pathway.

Introduction: Primary blast affects the kidneys due to direct shock wave damage and the production of proinflammatory cytokines without effective treatment. CD28 has been reported to be involved in regulating T cell activation and secretion of inflammatory cytokines. The aim of this study was to investigate the influence of primary blast on the kidney and the effect of CD28 in mice.
