Fig 2. Macrophage treated with different M. leprae antigens showed committed functional differentiation.
Live M. leprae-infected macrophages or killed M. leprae-treated macrophages were either restimulated with killed M. leprae, or cultured in plain culture medium for 6 days. Cytokine expression during the restimulation period was measured by Luminex assay. **: p < 0.01. ***: p < 0.001.
