用于癌症免疫治疗的基因组调控工具箱的超声控制

There remains a critical need for the precise control of CRISPR (clustered regularly interspaced short palindromic repeats)-based technologies.

Here, we engineer a set of inducible CRISPR-based tools controllable by focused ultrasound (FUS), which can penetrate deep and induce localized hyperthermia for transgene activation.

We demonstrate the capabilities of FUS-inducible CRISPR, CRISPR activation (CRISPRa), and CRISPR epigenetic editor (CRISPRee) in modulating the genome and epigenome.

We show that FUS-CRISPR-mediated telomere disruption primes solid tumours for chimeric antigen receptor (CAR)-T cell therapy.

We further deliver FUS-CRISPR in vivo using adeno-associated viruses (AAVs), followed by FUS-induced telomere disruption and the expression of a clinically validated antigen in a subpopulation of tumour cells, functioning as "training centers" to activate synthetic Notch (synNotch) CAR-T cells to produce CARs against a universal tumour antigen to exterminate neighboring tumour cells. The FUS-CRISPR(a/ee) toolbox hence allows the noninvasive and spatiotemporal control of genomic/epigenomic reprogramming for cancer treatment.
