Tuberculosis (TB) is a bacterial infectious disease caused by Mycobacterium tuberculosis, still considered a serious public health problem. It is estimated that one-third of the world's population is infected with M. tuberculosis, with the latent form of the disease which can be reactivated. Moreover, the lack of rapid and sensitive diagnostic, inadequate adherence to treatment and the acquisition of resistance to antibiotics by bacteria, further jeopardize this frame. With this project, new molecular targets aiming diagnosis and therapy will be explored. To explore the signaling pathways of the Notch receptor and its ligands will be a challenge of our project. This pathway is described as important in maintaining the immune response and can influence the dynamics of the immunity against bacilli. Another challenge will be understand how hypomethylation of cells from innate immunity could modulate the host response to infection. Currently, the use of drugs that act by modifying the DNA methylation pattern, the "epidrugs", have been explored as modulators of the immune response in tumors. Exploring the effect of these drugs during infections, considering their possibilities of clinical use is relevant in this scenario. Therefore, we wonder to investigate those two gaps in the literature, revealing immune response pathways that can be correlated with clinical data, and thereafter, new diagnostic and treatment biomarkers could be explored in this pathology.
