Pamela Cameron joined Moredun in 2003, after 4 years working at the Universities of Edinburgh and Strathclyde. Pam is interested in host/pathogen interactions and gained a BSc (Hons) in Immunology & Microbiology and a PhD in Immunology (University of Strathclyde). She also has an interest in Environmental Science and recently gained a Diploma in Environmental Studies (University of Exeter). Previous research has focused on understanding the signalling mechanisms behind E. coli O157:H7-induced pathophysiology in humans and cattle and the key differences between the two species. Pam also described how petidases from Leishmania mexicana selectively inhibit the NFkB pathway to thwart human immune defenses. Recent work has described key intracellular signalling molecules that are crucial to the pathogen-sensing mechanisms of intestinal epithelial cells, which are important in both E.coli O157:H7 and C. jejuni-mediated disease.
- Campylobacter jejuni is the number one cause of food poisoning in the UK, yet remarkably little is known about how C. jejuni initiates disease. Pam is using human intestinal cell models to investigate key intracellular events associated with infection.
- Analysing signalling pathways involved in the inflammatory and invasive properties of Campylobacter jejuni.
- Utilising proteomic approaches including SOSPA (sawn-off shotgun proteomic analysis), 2D gel electrophoresis, antibody microarray and signalling assays to understand the human pathogenic potential of C. jejuni.
- Applying proteomic approaches to investigate and compare the human pathogenic potential of a wide variety of C. jejuni sequence types (S.T.s).
