Electroacupuncture (EA) improves ovarian function by restoring neurovascular coupling, visualized using novel nanocrystals. This neuromodulation technique offers a new therapeutic strategy for conditions like polycystic ovary syndrome.
Area of Science:
- Biomedical Engineering
- Neuroscience
- Reproductive Biology
Background:
- Disrupted ovarian neurovascular coupling is linked to polycystic ovary syndrome.
- Electroacupuncture (EA) shows potential for improving ovarian function.
- Current methods lack real-time visualization of EA's neurovascular effects.
Purpose of the Study:
- To elucidate the mechanisms of EA-induced neurovascular changes in the ovary.
- To develop a real-time in vivo visualization strategy for ovarian neurovascular dynamics.
- To investigate the role of Netrin-1 in EA's therapeutic effects.
Main Methods:
- Utilized core-shell lanthanide nanocrystals for deep-tissue imaging in the NIR-II-L window.
- Performed real-time, high-resolution visualization of ovarian blood vessels during EA.
- Analyzed immediate (iEA) and cumulative (cEA) EA effects on vasodilation and perfusion.
- Validated the involvement of Netrin-1.
Main Results:
- EA induced transient ovarian vasodilation (iEA) and sustained improvements in perfusion and follicular development (cEA).
- EA strengthened sympathetic-vascular coupling.
- Netrin-1 was identified as a key mediator of EA's effects on ovarian neurovascular remodeling.
Conclusions:
- EA modulates ovarian function through specific neurovascular mechanisms.
- Lanthanide nanocrystals provide a powerful tool for visualizing in vivo neurovascular remodeling.
- This study offers insights into EA's therapeutic potential for ovarian disorders.
