564-感觉神经元驱动三阴性乳腺癌免疫逃逸及基质重塑

from 聊聊Sci

这项研究揭示了神经系统如何通过三阴性乳腺癌 (TNBC) 中的周围神经侵犯 (PNI) 影响病理进展和免疫治疗效果。研究发现,由感觉神经分泌的降钙素基因相关肽 (CGRP) 会诱导癌症相关成纤维细胞 (CAFs) 转化为肌成纤维细胞表型,进而加速胶原蛋白沉积并重塑肿瘤微环境。这种由神经介导的病理变化形成了免疫排斥屏障,阻碍了免疫细胞的浸润,使肿瘤对免疫检查点抑制剂产生耐药性。临床数据表明,正向 PNI 状态与患者预后不良及高转移率显著相关,且 CGRP 水平可作为预测疗效的生物标志物。实验证明,将 CGRP 抑制剂(如瑞美吉泮)与 PD-1 抗体联合使用,能有效降低组织纤维化并增强抗肿瘤免疫反应。这种创新疗法为攻克高度侵袭性且易耐药的三阴性乳腺癌提供了全新的临床策略。References: Zhang S W, Wang H, Xiao Y, et al.
