H2HUBB TAKEAWAY
In the present study, H₂ inhalation conferred an improved neurological outcome after TBI by significantly decreasing neuroinflammation and activating microglial M2 polarization via inhibition of histone deacetylase 5 (HDAC5) expression. The authors concluded that altogether, these data indicate that H₂ inhalation inhibits neuroinflammation and rescues neurological function after TBI by promoting M2 polarization of microglia through GSK3β/AKT signaling and AMPK-dependent mediation of HDAC5. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
