Immune Regulation of Intestinal Stem Cell Proliferation and Differentiation in Drosophila.

M. Shin, M. Ferguson, R. J. Willms, L. O. Jones, K. Petkau, E. Foley

This study shows that immune signaling in Drosophila intestinal stem cells is critical for maintaining epithelial homeostasis, with impaired immunity leading to reduced stem cell numbers and defective differentiation.

Differential effects of commensal bacteria on progenitor cell adhesion, division symmetry and tumorigenesis in the Drosophila intestine.

M. Ferguson, K. Petkau, M. Shin, A. Galenza, D. Fast, E. Foley

This study shows that Lactobacillus brevis affects stem cell division symmetry and tumorigenesis in Drosophila intestine by altering integrin expression and distribution.

Complex symbiont-pathogen interactions inhibit intestinal repair

D. Fast, K. Petkau, M. Ferguson, M. Shin, A. Galenza, B. Kostiuk, S. Pukatzki, E. Foley

This study shows that Vibrio cholerae inhibits intestinal epithelial repair in Drosophila by interacting with symbiotic bacteria, highlighting the role of the type six secretion system in pathogenesis.

Constitutive Immune Activity Promotes Tumorigenesis in Drosophila Intestinal Progenitor Cells.

K. Petkau, M. Ferguson, S. Guntermann, E. Foley

This study shows that continuous immune activity in Drosophila intestinal progenitor cells disrupts homeostasis and promotes tumor formation.
