Type III Secretion in Chlamydia
Microbiology and Molecular Biology Reviews, 2023Type III secretion systems (T3SSs) are utilized by Gram-negative pathogens to enhance their pathogenesis. This secretion system is associated with the delivery of effectors through a needle-like structure from the bacterial cytosol directly into a target eukaryotic cell.

Regulation of type III secretion systems
Current Opinion in Microbiology, 2002Type III secretion systems are utilised by numerous Gram-negative bacteria to efficiently interact with a host. Appropriate expression of type III genes is achieved through the integration of several regulatory pathways that ultimately co-ordinate the activity of a central transcriptional activator usually belonging to the AraC family.

Port of entry – the type III secretion translocon
Trends in Microbiology, 2002Many Gram-negative plant and animal pathogenic bacteria use a specialized type III secretion system (TTSS) as a molecular syringe to inject effector proteins directly into the host cell. Protein translocation across the eukaryotic host cell membrane is presumably mediated by a bacterial translocon.

Type III secretion: what's in a name?
Trends in Microbiology, 2006The term 'type III secretion' has seen widespread use. However, problems persist in nomenclature. We propose that the standard abbreviation for this kind of secretion should be 'T3S' and that 'type III secretion system' should be abbreviated to 'T3SS'.

Type III Secretion: Building and Operating a Remarkable Nanomachine [PDF]
Trends in Biochemical Sciences, 2016 The Type III secretion system (T3SS) is a protein export pathway that is widespread in Gram-negative bacteria and delivers effector proteins directly into eukaryotic cells. At its core lie the injectisome (a sophisticated transmembrane secretion apparatus) and a complex network of specialized chaperones that target secretory proteins to the antechamber

The type III secretion injectisome
Nature Reviews Microbiology, 2006The type III secretion injectisome is a complex nanomachine that allows bacteria to deliver protein effectors across eukaryotic cellular membranes. In recent years, significant progress has been made in our understanding of its structure, assembly and mode of operation.

Expression and Secretion Hierarchy in the Nonflagellar Type III Secretion System
Future Microbiology, 2011Type III secretion systems that deliver bacterial proteins into eukaryotic cells are the basis for both symbiotic and pathogenic relationships between many Gram-negative bacteria and their hosts. Exploration of the structure, function and assembly of this secretion system has greatly enhanced our knowledge of bacterial ecology in the context of ...

Introduction to Type III Secretion Systems
2016Type III secretion (T3S) systems are found in a large number of gram-negative bacteria where they function to manipulate the biology of infected hosts. Hosts targeted by T3S systems are widely distributed in nature and are represented by animals and plants.

Analysis of Type III Secretion System Secreted Proteins
2016Secreted proteins of the T3SS vary from genus to genus. How secretion is induced in vitro also depends on the genus of bacteria. However, once those proteins are isolated the method for analyzing those proteins is largely the same. The following chapter outlines the specific induction of Yersinia secreted proteins and uniform analysis of those secreted

Type III secretion system (TTSS) is believed to have originally evolved from the flagellar export system and is now dispersed among a number of both animal- and plant-interacting gram-negative bacteria. The aim of much current research on TTSS is to understand the mechanisms involved in effector secretion/injection and what the effectors are doing ...
