Neutralization of TNF or disruption of TNF-R1 leads to fatal Mycobacterium bovis BCG infection. Here we used TNF-LT-alpha-deficient mice to test whether a complete disruption of TNF and LT-alpha reduces further host resistance to BCG infection. The bacterial burden especially in the lungs of TNF-LT-alpha-deficient mice was significantly increased and the mice succumbed to infection between 8 and 10 weeks. In the absence of TNF-LT-alpha the granulomatous response was severely impaired and delayed. The cells in the granulomas of TNF-LT-alpha-deficient mice expressed low levels of MHC class II and ICAM-1. They contained a few T cells and F4/80-positive macrophages expressing little iNOS and acid phosphatase activity. By contrast, the lethal action of endotoxin was dramatically reduced in BCG-infected TNF-LT-alpha-deficient mice. In summary, in the absence of TNF-LT-alpha the recruitment and activation of mononuclear cells in response to BCG infection were significantly delayed and reduced resulting in immature granulomas allowing uncontrolled fatal infection.
