TNF and abscess: To study if lack of abscess is due to uncontrolled bacterial growth in LT-deficient mice, we infected LT-deficient mice with a lower inoculum (5x105 CFU/mL) and our data showed increased bacterial load in 5-LO deficient mice, but did not detect any differences in the production of the inflammatory cytokine TNF-α and, the chemokine CXCL2 when compared to WT control.
