Helicobacter chronic stage inflammation undergoes fluctuations that are altered in tlpA mutants

K. S. Johnson, C. Yang, J. E. Carter, A. Worthington, E. K. Robinson, R. Lopez Magana, F. Salgado, I. Arnold, K. M. Ottemann

This study shows that H. pylori chronic inflammation fluctuates over time, and tlpA mutants alter these dynamics without affecting colonization levels in later stages.

The immunomodulatory dCache chemoreceptor TlpA of Helicobacter pylori binds multiple attractant and antagonistic ligands via distinct sites

K. S. Johnson, B. Elgamoudi, F. E.- C. Jen, C. J. Day, E. G. Sweeney, M. L. Pryce, K. Guillemin, T. Haselhorst, V. Korolik, K. M. Ottemann

This study identifies multiple ligands bound by the H. pylori chemoreceptor TlpA, revealing both attractant and antagonist functions through distinct binding sites.

Gene expression and chromatin accessibility during progressive EMT and MET linked to dynamic CTCF engagement

K. S. Johnson, S. Hussein, S. Song, P. Chakraborty, M. K. Jolly, M. Toneff, Y. Lin, J. Taube

The paper examines gene expression and chromatin accessibility changes during reversible EMT and MET in mammary epithelial cells, highlighting CTCF's role in chromatin reorganization and stemness.
