Ketamine attenuates sepsis-induced acute lung injury via regulation of HMGB1-RAGE pathways.
High mobility group box protein 1 (HMGB1) and receptor for the advanced glycation end product (RAGE) play important roles in the development of sepsis-induced acute lung injury (ALI). Ketamine is considered to confer protective effects on ALI during sepsis. In this study, we investigated the effects of ketamine on HMGB1-RAGE activation in a rat model of sepsis-induced ALI. ⋯ It also inhibited the activation of IκB-α, NF-κB p65, and MAPK. Ketamine protects rats against HMGB1-RAGE activation in a rat model of sepsis-induced ALI. These effects may partially result from reductions in NF-κB and MAPK.
