【 摘 要 】

Exposure to bacterial superantigens, such as staphylococcal enterotoxin B (SEB), can lead to the induction of acute lung injury/acute respiratory distress syndrome (ALI/ARDS). To date, there are no known effective treatments for SEB-induced inflammation. In the current study we investigated the potential use of the hyaluronic acid synthase inhibitor 4-methylumbelliferone (4-MU) on staphylococcal enterotoxin B (SEB) induced acute lung inflammation. Culturing SEB-activated immune cells with 4-MU led to reduced proliferation, reduced cytokine production as well as an increase in apoptosis when compared to untreated cells. Treatment of mice with 4-MU led to protection from SEB-induced lung injury. Specifically, 4-MU treatment led to a reduction in SEB-induced HA levels, reduction in lung permeability, and reduced pro-inflammatory cytokine production. Taken together, these results suggest that use of 4-MU to target hyaluronic acid production may be an effective treatment for the inflammatory response following exposure to SEB.
