Key Points

The study aims to understand how chronic stress leads to cellular changes in the brain that affect behavior and metabolism.
Chronic stress was applied to mice to assess its effects on behavior and physiological changes.
Behavioral assessments measured anxiety levels and hyperglycemia was also evaluated following stress exposure.
Chronic stress induced senescence in amygdala astrocytes, correlating with increased anxiety levels.
Hyperglycemia was observed as a physiological consequence of this stress-induced cellular senescence.
