1610-压电微针贴片调节黑色素瘤神经免疫通讯研究

from 聊聊Sci

这篇文章介绍了一种前沿纳米医学研究,旨在通过压电微针贴片(MT MN)阻断黑色素瘤中的神经—免疫相互作用。研究人员开发出一种掺锰钛基金属有机框架材料,并为其包裹神经元细胞膜,使其能精准识别并靶向肿瘤内的痛觉受体。在超声波驱动下,该材料产生的纳米局部电场可诱导TRPV1受体内吞,并激活cGAS-STING信号通路,协同抑制神经递质CGRP和SP的释放。实验结果表明,这种疗法能够有效逆转肿瘤微环境的免疫抑制状态,提升CD8+ T细胞的抗肿瘤活性。该技术通过物理刺激与生化调节相结合,为增强癌症免疫治疗效果提供了一种创新的微创介入手段。References:Song A, Zhang Y, Ji Y, et al.
