Infection of mucosal epithelial cells by Shigella species leads to an intense and acute inflammatory bowel disease that is characterized by watery diarrhea and purulent discharge. Mucin production is a common defense mechanism to protect the underlying mucosa against pathogens. The molecular mechanism(s) underlying mucin induction is unknown in Shigellosis. In this study, we have evaluated the relationship between Shigella infection, the expression of MUC2 and MUC5AC and the participation of signaling molecules TNF-α, PKC and ERK1/2. Shigella infection up-regulated MUC2 and MUC5AC expression in 6-8 h, through activation of TNF-α, PKC and ERK1/2. These results confirm that, in response to Shigella infection, the normal expression pattern of MUC-2 and MUC-5AC is altered. This in vivo study brings new insights into the molecular pathogenesis of Shigellosis and new potential therapeutic targets for Shigellosis.
