ABSTRACT (Mtb), the causative agent of tuberculosis, is one of the most successful human pathogens. One reason for its success is that Mtb can reside within host macrophages, a cell type that normally functions to phagocytose and destroy infectious bacteria. However, Mtb is able to evade macrophage defenses in order to survive for prolonged periods of time. Many intracellular pathogens secrete virulence factors targeting host membranes and organelles to remodel their intracellular environmental niche. We hypothesized that Mtb secreted proteins that target host membranes are vital for Mtb to adapt to and manipulate the host environment for survival. Thus, we characterized 200 secreted proteins from Mtb for their ability to associate with eukaryotic membranes using a unique temperature-sensitive yeast screen and to manipulate host trafficking pathways using a modified inducible secretion screen. We identified five Rabbit polyclonal to ABHD12B Mtb secreted protein that both connected with eukaryotic membranes and changed the web host secretory pathway. Among these secreted Calcium D-Panthotenate protein, Mpt64, localized towards the endoplasmic reticulum during Mtb infections of murine and individual macrophages and impaired the unfolded proteins response in macrophages. These data high light the need for secreted protein in Mtb pathogenesis and offer a basis for even more investigation to their molecular systems. IMPORTANCE Calcium D-Panthotenate Advances have already been made Calcium D-Panthotenate to recognize secreted proteins of during pet attacks. These data, coupled with transposon screens determining genes important.
