Gut metabolite L-lactate supports Campylobacter jejuni population expansion during acute infection

R. Sinha, R. M. LeVeque, S. M. Callahan, N. Stopnisek, M. Kuipel, J. G. Johnson, V. J. DiRita

This study identifies L-lactate as a key metabolite supporting Campylobacter jejuni growth during acute infection in ferrets, revealing a regulatory mechanism involving the LctR protein.

Battle for the histones: a secreted bacterial sirtuin from Campylobacter jejuni activates neutrophils and induces inflammation during infection

S. M. Callahan, T. J. Hancock, R. S. Doster, C. B. Parker, M. E. Wakim, J. A. Gaddy, J. G. Johnson

This study identifies a secreted bacterial sirtuin, SliP, from Campylobacter jejuni that deacetylates host histones, activates neutrophils, and drives inflammation during infection.

Campylobacter jejuni induces differentiation of human neutrophils to the CD16hi/CD62Llo subtype which possess cancer promoting activities

C. G. Dolislager, S. M. Callahan, D. R. Donohoe, J. G. Johnson

This study shows that Campylobacter jejuni induces human neutrophils to differentiate into CD16hi/CD62Llo subtype, which promotes cancer-related activities in T cells and colonocytes.
