Expression of IL-32 is detected in different cells. Fragments of cutaneous or mucosal lesions were included in paraffin and sections were submitted to IHC for IL-32. The arrows show positive cells: In panel A: mononuclear cell and giant cell; and Panel B: endothelial cells and giant cell. In Panel C: positive keratinocytes; and Panel D: several positive mononuclear cells. The expression of IL-32 was determined, under light microscopy, in epithelium and infiltrate of CL (E, n = 22) and ML (F, n = 9). The data represent individual and median values.
