The matrix remembers.

Intestinal inflammation leaves a durable extracellular matrix imprint that influences stem-cell fate and promotes persistent immune activation.

• Why it matters: Understanding how inflammation causes lasting tissue changes is crucial for addressing chronic inflammatory diseases, yet the mechanisms remain poorly understood.
• What they did: Adir and colleagues used experimental approaches to show that inflammation modifies the extracellular matrix, which then redirects stem-cell fate and sustains epithelial and immune responses.
• The result: This extracellular matrix memory may serve as a mechanism linking resolved injury to chronic inflammation, offering potential targets for therapeutic intervention.
