Myrrh Inhibits LPS-Induced Inflammatory Response and Protects from Cecal Ligation and Puncture-Induced Sepsis

الملخص EN

Myrrh has been used as an antibacterial and anti-inflammatory agent.

However, effect of myrrh on peritoneal macrophages and clinically relevant models of septic shock, such as cecal ligation and puncture (CLP), is not well understood.

Here, we investigated the inhibitory effect and mechanism(s) of myrrh on inflammatory responses.

Myrrh inhibited LPS-induced productions of inflammatory mediators such as nitric oxide, prostaglandin E2, and tumor necrosis factor-α but not of interleukin (IL)-1β and IL-6 in peritoneal macrophages.

In addition, Myrrh inhibited LPS-induced activation of c-jun NH2-terminal kinase (JNK) but not of extracellular signal-regulated kinase (ERK), p38, and nuclear factor-κB.

Administration of Myrrh reduced the CLP-induced mortality and bacterial counts and inhibited inflammatory mediators.

Furthermore, administration of Myrrh attenuated CLP-induced liver damages, which were mainly evidenced by decreased infiltration of leukocytes and aspartate aminotransferase/alanine aminotransferase level.

Taken together, these results provide the evidence for the anti-inflammatory and antibacterial potential of Myrrh in sepsis.
