RUSH3D-HR microscope reveals how electroacupuncture halts immune cell surge
Synopsis
Key Takeaways
A Chinese research team has used a next-generation RUSH3D-HR mesoscale microscope to capture, for the first time in real time, how electroacupuncture suppresses the movement of immune cells inside living mice — delivering direct visual evidence of the ancient therapy's anti-inflammatory mechanism. The findings were published in the peer-reviewed journal Nature Biotechnology on July 15, 2026.
What the microscope revealed
Scientists used RUSH3D-HR to observe thousands of immune cells swarming toward sites of induced inflammation in the mouse spleen. When electroacupuncture was applied to a specific acupoint below the knee — known as Zusanli (ST36) — the cellular surge was visibly and measurably suppressed. The imagery provided what researchers described as vivid, real-time evidence of acupuncture's biological anti-inflammatory action.
The team and the technology
The study was conducted by a collaborative team from Tsinghua University, Tongji Hospital, and Zhejiang Hehu Technology. According to the research team, 'millions of cells and organelles in mammals continuously migrate, interact and orchestrate to form sophisticated populational dynamics that drive diverse functionalities in different physiological or pathological states.' The RUSH3D-HR system was designed to address the longstanding challenge of imaging large volumes of living tissue at high resolution without causing significant damage.
Why it matters
Previous imaging methods required trade-offs between resolution, field of view, and tissue damage over extended observation periods. The new system reportedly allows scientists to study complex biological processes in live animals over long durations with reduced tissue disruption — potentially accelerating understanding of immune response, disease progression, and therapeutic targets. The direct visualisation of acupuncture's cellular effects marks a significant methodological leap for a field that has historically struggled to produce mechanistic evidence acceptable to Western biomedical standards.
The competitive backdrop
China has been systematically investing in advanced bioimaging and life-sciences instrumentation as part of its push for self-sufficiency in core scientific tools. Institutions such as Tsinghua University and industry partners like Zhejiang Hehu Technology are central to that effort. The publication in Nature Biotechnology — one of the most selective journals in the field — signals that the instrumentation and the underlying science have cleared rigorous international peer review.
What's next
The RUSH3D-HR platform is expected to be applied beyond acupuncture research to broader studies of immune dynamics, cancer progression, and drug response in living organisms. The team's work opens the door to a new class of longitudinal in-vivo studies that were previously impractical. Researchers and pharmaceutical developers studying inflammation pathways are likely to be among the earliest adopters of the technology.
