Drosophila TNF/TNFRs: At the crossroad between metabolism, immunity, and tissue homeostasis

J Colombani, DS Andersen - FEBS letters, 2023‏ - Wiley Online Library
Tumor necrosis factor (TNF)‐α is a highly conserved proinflammatory cytokine with important

Inter-cell type interactions that control JNK signaling in the Drosophila intestine

P Zhang, SM Pronovost, M Marchetti, C Zhang… - Nature …, 2024‏ - nature.com
JNK signaling is a critical regulator of inflammation and regeneration, but how it is controlled
in specific tissue contexts remains unclear. Here we show that, in the Drosophila intestine …

Tissue homeostasis and non-homeostasis: from cell life cycles to organ states

LE O'Brien - Annual review of cell and developmental biology, 2022‏ - annualreviews.org
Although tissue homeostasis—the steady state—implies stability, our organs are in a state of
continual, large-scale cellular flux. This flux underpins an organ's ability to homeostatically …

Multiscale analysis reveals that diet-dependent midgut plasticity emerges from alterations in both stem cell niche coupling and enterocyte size

A Bonfini, AJ Dobson, D Duneau, J Revah, X Liu… - Elife, 2021‏ - elifesciences.org
The gut is the primary interface between an animal and food, but how it adapts to qualitative
dietary variation is poorly defined. We find that the Drosophila midgut plastically resizes …

Stem cell mTOR signaling directs region-specific cell fate decisions during intestinal nutrient adaptation

J Mattila, A Viitanen, G Fabris, T Strutynska… - Science …, 2024‏ - science.org
The adult intestine is a regionalized organ, whose size and cellular composition are
adjusted in response to nutrient status. This involves dynamic regulation of intestinal stem …
