The manipulation of cell surface receptors’ activity will open a new frontier for drug development and disease treatment. However, limited by the desensitization of drugs, effective physical intervention strategy remains challenging. Here, the controllable internalization of transient receptor potential vanilloid 1 (TRPV1) on neural cells by local piezoelectric field is reported. Single‐cell‐level local electric field is construct by synthesizing piezoelectric BiOIO3 nanosheets (BIONSs). Upon a mild ultrasound of 0.08 W cm−2, an electric field of 15.29 µV is generated on the surface of BIONSs, further inducing TRPV1 internalization in 5 min. The as‐downregulated TRPV1 expression results in the reduction of Ca2+ signal in a spinal neuron and the inhibition of the activity of wide range dynamic neurons, therefore effectively preventing the transmission of cancer‐induced bone pain (CIBP). This strategy not only charts a new course for CIBP alleviation, but also introduces a promising nanotechnology for regulating cell surface receptors, showing significant potential in neuropathological and receptor‐related diseases.

压电镇痛可阻止癌症引起的骨痛



细胞表面受体活性的操纵将为药物开发和疾病治疗开辟新领域。然而,受限于药物脱敏作用,有效的物理干预策略仍然具有挑战性。在此,报道了通过局部压电场对神经细胞的瞬时受体电位香草酸 1 (TRPV1) 的可控内化。通过合成压电 BiOIO3 纳米片(BIONS)构建单细胞级局部电场。在 0.08 W cm−2 的温和超声下,BIONS 表面产生 15.29 µV 的电场,在 5 分钟内进一步诱导 TRPV1 内化。 TRPV1表达下调导致脊髓神经元中Ca2+信号减少并抑制大范围动态神经元的活性,从而有效防止癌症引起的骨痛(CIBP)的传播。该策略不仅为缓解 CIBP 开辟了一条新路线,而且还引入了一种有前途的调节细胞表面受体的纳米技术,在神经病理学和受体相关疾病方面显示出巨大的潜力。
