The Caspase Pathway as a Possible Therapeutic Target in Experimental Pemphigus

Figure 4

Caspase 3 activity detected in mouse skin. Note the presence of caspase 3 in a blister induced by the injection of pemphigus vulgaris IgG, and the presence of cytokeratin 18 detected using the antibody M30 which recognises a neoepitope of cytokeratin 18 formed after caspase cleavage. Positive immunohistochemistry was exhibited in both cases (arrows). Note the inhibition induced by the synthetic peptide Ac-DEVD-CMK in the bottom row.
