Mycobacterium tuberculosis PE/PPE family proteins, named after the presence of conserved PE (Pro-Glu) and PPE (Pro-Pro-Glu) domains at N-terminal, are prevalent in M. tuberculosis genome. The function of most PE/PPE family proteins remains elusive. To characterize the function of PE_PGRS18, the encoding gene was heterologously expressed in M. smegmatis, a nonpathogenic mycobacterium. The recombinant...
PE/PPE family proteins are mycobacteria unique molecules, named after their N-terminal conserved PE (Pro-Glu) and PPE (Pro-Pro-Glu) domains. Mycobacterium tuberculosis (Mtb) PE family gene encoded cell surface proteins are previously reported to be involved in virulence and interaction with host. To explore the role of a novel PE member (PE13, Rv1195), M. smegmatis was used as surrogate host. The...
Tuberculosis remains a serious human public health concern. The coevolution between its pathogen Mycobacterium tuberculosis and human host complicated the way to prevent and cure TB. Apoptosis plays subtle role in this interaction. The pathogen endeavors to manipulate the apoptosis via diverse effectors targeting key signaling nodes. In this paper, we summarized the effectors pathogen used to subvert...
