Project Description

Chlamydia trachomatis remains the principal bacterial cause of sexually transmitted infections worldwide. In Developing nations, ocular infections cause trachoma, a form of blindness, which is designated by the World Health Organisation as a neglected tropical disease. Chlamydiae are obligate intracellular bacteria that adopt two distinct developmental forms, infectious elementary bodies (EB) force their own actin-dependent uptake into epithelial cells. Once internalised EB differentiate to form reticulate bodies (RB) that survive and replicate within a specialised intracellular compartment called an inclusion. RB re-differentiate into EB and induce inclusion egress or cell lysis to continue the lifecycle. Bacterial virulence effector proteins that are translocated into the host cell control inclusion biogenesis. These effectors integrate into the inclusion membrane, and disseminate into the cytosol and nucleus of the infected cell, where they hijack key host processes including intracellular trafficking, antigen presentation, cytoskeletal architecture, organelle interactions and host gene expression. This project will apply a multidisciplinary approach to investigate the structure and function of chlamydial effectors, involving protein biochemistry, cell biology and infection models in cultured cells, bioimaging and the application of genetic techniques that have only recently been developed in the field. The aim is to identify targets of effectors of unknown function, and to understand the role of the targetted host processes in inclusion biogenesis and disease. In parallel, the project will involve the characterisation of novel host targets we have already identified in ongoing work. Since little is known about the biogenesis of the inclusion this work not only provides training in a wide variety of techniques but also the opportunity to study new aspects of host cell biology.

Funding Notes

Funding* will cover the student’s stipend at the current Research Council rate and University Fees. The studentships will be funded for three years in the first instance subject to eligibility**, with the possibility of additional funding in the fourth year depending on circumstances.

**The studentships are available to students who qualify for Home/EU fees

Applications from ineligible candidates will not be considered.
