Periodic Reporting for period 1 - ESX-4 T7SS (Structure/function of a prototypic type VII secretion system from a fast-growing pathogenic mycobacteria)
Période du rapport: 2019-04-01 au 2021-03-31
This project aimed at studying a secretion system, specific to mycobacteria, called the Type VII Secretion system (T7SS). T7SS allows the bacteria to import important nutrients, while exporting virulent factors that lets the bacteria evade the human immune system. Therefore, this makes this study of T7SS so attractive: if we could design a drug that would block the import of essential nutrient for the bacteria, we could starve it to death; or we could attempt to block the secretion of the virulent factors and let our immune system take care of the bacteria. During this project, information was gathered on the 3D structure of the T7SS complex machinery and, in collaboration with laboratories from Germany and France, more information was gathered on the factors secreted by T7SS and their impact on our immune system.
