Bee Venom Component May Help Treat Acute Pancreatitis

Melittin Inhibits Cerulein-Induced Acute Pancreatitis via Inhibition of the JNK Pathway
Int Immunopharmacol, 2011 Sep 20. [Epub ahead of print]

The major compound of bee venom, melittin, has been used as an anti-inflammatory reagent for decades. However, the potential of melittin to ameliorate acute pancreatitis (AP) is unknown.

Our aim was to investigate the effect of melittin on cerulein-induced AP. Pre- and post-treatment with melittin inhibited histological changes in the pancreas and lungs during cerulein-induced AP.

Pancreatic weight/body weight ratios; digestive enzymes, including amylase and lipase; serum and pancreatic cytokine expression; and myeloperoxidase activity were decreased. In addition, treatment with melittin inhibited the activation of c-Jun NH(2)-terminal protein kinase (JNK) in the pancreas during cerulein-induced pancreatitis.

In accordance with the results of in vivo experiments, melittin reduced cerulein-induced cell death, and production of inflammatory cytokines.

In conclusion, our results suggest that melittin attenuated AP and AP-associated lung injury through the inhibition of JNK activation.
