 Figure 1. MGC show increased tyrosine nitration in response to mycobacteria and TLR2/MyD88 dependency. A Histological sections from biopsies of an osteolytic lesion of the calcaneus from a patient with M.xenopi infection, at onset of disease (1st) and 2 months later (2nd) were quantified by microscopy with hematoxylin/eosin staining and by liquid cultures (table). Image of immunohistochemistry for nitrotyrosine (red) and hematoxylin counterstaining of 2nd biopsy samples, dashed line indicating MGC; scale bar, 20µm.
