Phylogeographic diversity and mosaicism of the Helicobacter pylori tfs integrative and conjugative elements (2018)
Journal Article
Delahay, R. M., Croxall, N. J., & Stephens, A. D. (in press). Phylogeographic diversity and mosaicism of the Helicobacter pylori tfs integrative and conjugative elements. Mobile DNA, 9(5), https://doi.org/10.1186/s13100-018-0109-4

Background: The genome of the gastric pathogen Helicobacter pylori is characterised by considerable variation of both gene sequence and content, much of which is contained within three large genomic islands comprising the cag pathogenicity island (ca...

A role for the tfs3 ICE-encoded type IV secretion system in pro-inflammatory signalling by the Helicobacter pylori Ser/Thr kinase, CtkA (2017)
Journal Article
Alandiyjany, M. N., Croxall, N. J., Grove, J. I., & Delahay, R. M. (2017). A role for the tfs3 ICE-encoded type IV secretion system in pro-inflammatory signalling by the Helicobacter pylori Ser/Thr kinase, CtkA. PLoS ONE, 12(7), Article e0182144. https://doi.org/10.1371/journal.pone.0182144

Two distinct type IV secretion systems (T4SSs) can be identified in certain Helicobacter pylori strains, encoded on mobile genetic elements termed tfs3 and tfs4. Although their function remains unknown, both have been implicated in clinical outcomes...

A role for the vacuolating cytotoxin, VacA, in colonisation and Helicobacter pylori-induced metaplasia in the stomach (2014)
Journal Article
Winter, J., Letley, D., Cook, K., Rhead, J., Zaitoun, A., Ingram, R., …Atherton, J. (2014). A role for the vacuolating cytotoxin, VacA, in colonisation and Helicobacter pylori-induced metaplasia in the stomach. Journal of Infectious Diseases, 210(6), 954–963. https://doi.org/10.1093/infdis/jiu154

Carriage of Helicobacter pylori strains producing more active (s1/i1) forms of VacA is strongly associated with gastric adenocarcinoma. To our knowledge, we are the first to determine effects of different polymorphic forms of VacA on inflammation and...
