Ferroplasticity drives social isolation-induced anxiety via a ventral hippocampal iron-α-synuclein axis

Key Points

• Social isolation increases anxiety linked to ferroplasticity activity in the ventral hippocampus, indicating potential pathways for treatment.
• Elevated alpha-synuclein levels correlate with anxiety symptoms observed in isolated subjects, highlighting a crucial biomarker.
• Assessment using animal models demonstrates that manipulation of iron levels can alter anxiety behaviors related to social conditions.
• Findings underscore the importance of the iron-alpha-synuclein axis in understanding anxiety mechanisms under social isolation.
