Lung iNOS expression in established TB lesions is similar between euglycemic and chronic diabetic mice. A euglycemic control C57BL/6 mouse (A), an STZ-treated chronic diabetic mouse (B), a euglycemic wild-type C57BL/6J control for the Akita mice (C), and a chronic diabetic Akita mouse (D) were infected with Mtb Erdman by aerosol. Lung sections prepared 16 weeks after infection were stained with anti-iNOS/NOS II. Cells expressing iNOS are identified by brown staining. Images are ×40 magnification.
