High Intensity Focused Ultrasound (HIFU) Triggers Immune Sensitization of Refractory Murine Neuroblastoma to Checkpoint Inhibitor Therapy.

Magnetic frequencies are not the only alternatives:

"Combining HIFU with αCTLA-4 and αPD-L1 significantly enhances anti-tumor response, improving survival from 0 to 62.5%.
HIFU alone causes upregulation of splenic and lymph node NK cells and circulating IL-2, IFN-Ɣ, and DAMPs, whereas immune regulators like CD4+Foxp3+, IL-10, and VEGF-A are significantly reduced.
HIFU combined with checkpoint inhibitors induced significant increases in intratumoral CD4+, CD8ɑ+, and CD8α+CD11c+ cells, CD11c+ in regional lymph nodes, and decrease in circulating IL-10 compared to untreated group.
We also report significant abscopal effect following unilateral treatment of mice with large, established bilateral tumors using HIFU and checkpoint inhibitors compared to tumors treated with HIFU or checkpoint inhibitors alone (61.1% survival, p<0.0001).
This combination treatment significantly also induces CD4+CD44+hiCD62L+low and, CD8α+CD44+hiCD62L+low population and are adoptively transferable imparting immunity, slowing subsequent de novo tumor engraftment."
