Title of the Project
Cellular and molecular mechanisms involved in tuberculosis-mediated exacerbation of HIV-1 infection in macrophages: focus on Siglec-1 and tunneling nanotubes

Context and Project
Co-infection with Mycobacterium tuberculosis (Mtb), the etiological agent of tuberculosis (TB), and HIV-1 is major health issue in the world. The synergistic relationship between HIV-1 and Mtb is known to result in increased pathogen proliferation and associated pathogenesis. In this context, we recently demonstrated that tunneling nanotubes (TNT) are cellular structures induced by a TB-associated microenvironment that favors HIV-1 spread among macrophages, enhancing virus load as observed in HIV/TB co-infected patients.
