Tumor necrosis factor (TNF) is a critical mediator in the immune response to mycobacteria, particularly in the formation and maintenance of granulomas. Treatment of Mycobacterium bovis BCG-infected mice with TNF and a TNF-mimetic peptide (TNF70-80) altered the number and cellular composition of granulomas. This change was associated with a moderate decrease in the bacterial burden.
