• 5 macrophage populations: resting, activated, Mtb-infected in eclipse stage, Mtb-infected in productive stage, HIV-infected• 3 CD4+ T cells: susceptible, HIV-infected in eclipse stage, productively infected• 2 CD8+ (CTLs) populations: HIV-specific and Mtb-specific• No Mtb-HIV coinfected cells• Simulates HIV disease progression – early, late, AIDS• Inhibition of bacterial growth or bacterial death to simulate TB drugs (2 drugs)• ART is included by term that reduces HIV infection with modification for TB-HIV drug interaction (2 drugs). This evidence concerns the gene CD4 and AIDS.
