Towards a better diagnosis for HIV/tuberculosis co-infection

By 26th March 2019 June 11th, 2019 No Comments

1.2 million people in the world are co-infected by Mycobacterium tuberculosis, the bacteria which causes tuberculosis, and AIDS (HIV-1). This combination is deadly: it makes patient diagnosis and treatment difficult, and increases the pathogenicity of these two infectious agents. An international team led by researchers at the CNRS and Inserm have shown that in the presence of tuberculosis, HIV-1 moves from one cell to another via nanotubes which form between macrophages, drastically increasing the percentage of infected cells. These findings are reported in Cell Reports.
