BDNF Exacerbates Visceral Hypersensitivity through Hippocampal TrkB-CRF Signaling in Early-Life Stress

Key Points

• The research investigates how BDNF influences visceral hypersensitivity and anxiety linked to early-life stress through specific signaling pathways.
• Examined BDNF's role in anxiety and hypersensitivity following early-life stress.
• Analyzed the signaling mechanisms in the hippocampus, focusing on TrkB and CRF pathways.
• Utilized experimental models to assess behavioral outcomes related to anxiety and sensitivity.
• Findings indicate that BDNF significantly increases visceral hypersensitivity in response to early-life stress.
• The interaction between hippocampal TrkB signaling and CRF is crucial in mediating these effects.
• Results provide a potential target for treating stress-related irritable bowel syndrome (IBS).
