1: To determine the evolution of Mtb-specific Th22 CD4+ cells during TB disease and treatment. 2: To define the dynamics of Mtb Th22 responses in LTBI and HIV co-infection after antiretroviral (ART). 3: To examine Mtb-specific Th22 cells along the spectrum of TB infection and disease.
Observational study
Tuberculosis (TB) remains a leading cause of death from an infectious disease. 10.6 million people developed TB in 2022, including over 1.3 million children, and 1.3 million people died of TB. The need for new and improved ways to prevent the spread of TB is greater than ever. An effective vaccine and biomarkers to identify those at greatest risk of disease will be key to reducing TB. The challenge with developing these interventions is that we lack an understanding of why some people who become infected with Mycobacterium tuberculosis (M.tb), the bacterium causing TB, do not develop disease, while others do. In this project, we are investigating a range of CD4 T helper cell subsets that form part of the adaptive response to M.tb. In the fifth year of the project, we have continued to study CD4 helper subsets in TB immunity, focusing on those who are highly exposed to TB due to occupational exposure, and yet appear to resist infection. http://www.idm.uct.ac.za/Wendy_Burgers

To examine the effect of HIV co-infection on the immune response to Mycobacterium tuberculosis. The proposed research aims to identify aspects of the immune response to M.tb which differ in persons latently infected with TB in the presence or absence of HIV co-infection.
