Peptide treatment strategy for the animal experiment in Figures 4(b), 4(c), or 4(d).

GroupPeptide administration strategy

G1 ( = 12 or 15)LPS (100 μL*, iv)
G2 ( = 12)LPS (100 μL, iv), 5 minutes later, Regasepin 2 (100 μL**, iv)
G3 ( = 12)P2 (200 μL#, ip), wait for some time##, LPS (100 μL, iv)

LPS is dissolved in sterile 0.9% saline at a concentration of 2 μg/µL. Regasepin 2 was dissolved in sterile 0.9% saline at a concentration of 7 mg/mL. #The concentration of P2 was 15 mg/mL; ##the time interval was 30, 60, or 90 minutes for the experiments shown in Figures 4(b), 4(c), or 4(d).
