We found that also in the WT situation, Shp expression gradually decreased, while Cxcl2 expression increased until 6 h, and vice versa at 24 h upon ConA-treatment, indicating an inverse correlation between Shp and Cxcl2 expression during ConA-induced hepatitis.
Further understanding of the regulatory mechanisms of MIP-2 secretion and activation may be helpful to develop MIP-2-targeted therapeutic strategies to prevent liver inflammation.
The E. chaffeensis strain Wakulla induces diffuse hepatitis with neutrophil infiltration in mice with severe combined immunodeficiency, which is accompanied by strong CXCL2 (mouse functional homolog of interleukin-8 [IL-8]) and tumor necrosis factor alpha (TNF-α) expression in the liver.
