  ABSTRACT: Enhancement of the Human Immunodeficiency Virus (HIV) specific cytotoxic T-cells mechanisms in an HIV-1 and Mycobacterium tuberculosis (Mtb) co-infected individual seems to improve the clinical picture of an individual by reducing Acquired Immuno Deficiency Syndrome (AIDS) state progression rate. In this paper, we develop a system of deterministic differential equations representing the immune cells involved in an HIV-1 and Mtb co-infected individual. Results show that although the non-lytic arm of the HIV-1 cytotoxic T-cells affects the co-infection dynamics more than the lytic factors, a combination of both factors results in a more positive reduced progression to the AIDS state. This is due to the increased protection of the CD4+ T-cells by the CTL mechanisms by further reducing infections and replications by the HIV. Thus, HIV-1 specific CTLs mechanisms’ involvement is here recommended to be part of a solution to the HIV and Mtb co-infection problems.
