Galectin-3 expression in leprosy lesions. Galectin-3 protein expression in the skin lesions of lepromatous leprosy (L-lep; n = 3) and tuberculoid leprosy (T-lep; n = 3) patients was investigated by immunohistochemical staining with monoclonal mouse anti-human galectin-3 (B2C10). Four-micrometer tissue sections of leprosy skin biopsy specimens were incubated with anti–galectin-3 and labeled with an immunoperoxidase method followed by hematoxylin for visualization of histology. Tissue sections labeled with isotype control antibodies were negative. Photographs were taken using ×10 and ×40 objective lenses. Scale bars = 50 μm.
