GRIN2B and Sepsis: Post hoc comparisons showed that sepsis led to significantly decreased expressions of post-synaptic protein PSD95 and GluN2B at 24 h (all p < 0.05) and 16 days (all p < 0.001) following CLP in the hippocampus, which were significantly attenuated by clenbuterol treatment (all p < 0.05) and 16 days (all p < 0.001).
