大脑中的生长因子对于抑郁症及其治疗很重要,我们评估了外周给药的胰岛素样生长因子-I (IGF-I) 影响抑郁症相关行为的能力。我们发现,接受长期 IGF-I 治疗的小鼠在强迫游泳和新奇诱发的吞咽不足 (NIH) 测试中表现出抗抑郁样行为,并且在慢性轻度不可预测的压力暴露后,蔗糖消耗量增加。此外,在强迫游泳试验(FST)中,外周抗 IGF-I 给药可阻断运动诱发的抗抑郁作用。这些结果支持神经营养机制与抑郁症的功能相关性,并将这一想法扩展到包括外周神经营养因子。
Growth factors in the brain are important to depression and it’s treatment and we assessed the ability of peripherally administered insulin-like growth factor-I (IGF-I) to influence behavior related to depression. We found that mice that received chronic IGF-I treatment showed antidepressant-like behavior in forced-swim and novelty-induced hypophagia (NIH) tests and increased sucrose consumption after chronic mild unpredictable stress exposure. Additionally, peripheral anti-IGF-I administration blocked exercise-induced antidepressant effects in the forced-swim test (FST). These results support the functional relevance of neurotrophic mechanisms to depression and extend this idea to include neurotrophic factors in the periphery.
