641-脑-肠轴多突触环路调控结直肠癌生长

from 聊聊Sci

这项研究揭示了结直肠癌细胞如何通过“劫持”一种从大脑外侧隔区(LS)到肠道神经元的多级突触回路,来维持肿瘤的生长。研究发现,该大脑区域中的GABA能神经元与肠道中的胆碱能神经元相连,并共同构成了一条对压力刺激敏感的神经通路。当该回路被激活时,会促使肿瘤微环境中的神经纤维释放GABA,这种神经递质随后通过激活肿瘤细胞上的特定受体来加速病情恶化。实验证明,无论是心理压力还是人工激活该通路都会促进肿瘤扩张,而阻断这一回路则能显著抑制结直肠癌的发展。临床数据进一步证实,隔区神经活动较高的患者往往拥有更大的原发性肿瘤。该成果为通过干预脑-瘤轴及心理应激来治疗癌症提供了全新的科学依据。References: Li Y, Yu H, Li Z M, et al.
