Systemic SEB treatment evokes an increase in Hsp25 and Hsp72 in epithelial cells and gut lymphocytes. BALB/c mice were injected intraperitoneally with 5 μg of SEB, and the jejuna were harvested 4 or 24 h later. Tissues were formalin fixed, and immunohistochemistry was performed on paraffin sections as described in Materials and Methods. Images shown are representative of the results from 4 mice.
