Single-Cell RNA Sequencing Reveals the Therapeutic Effects of Electroacupuncture at BL23 on Hyperuricemia-Induced Nephritis.

Researchers investigated whether electroacupuncture at the BL23 acupuncture point could help treat hyperuricemia (high uric acid levels in the blood) and the kidney damage it can cause. Hyperuricemia affects millions of people and can lead to gout and serious kidney problems if left untreated. In this animal study, mice with experimentally induced hyperuricemia received electroacupuncture treatment at BL23, a point located on the lower back that traditional Chinese medicine associates with kidney function. The mice were treated once daily while being given substances that raised their uric acid levels. The results showed that electroacupuncture significantly reduced uric acid levels in the blood and improved multiple markers of kidney function. The treatment decreased creatinine and blood urea nitrogen levels, reduced protein in the urine, and increased the excretion of creatinine—all signs of better kidney health. The researchers also found that electroacupuncture reduced inflammation throughout the body by lowering inflammatory proteins like IL-1β, IL-6, and TNF-α. Using advanced genetic sequencing technology, they discovered that the treatment worked by suppressing specific inflammatory pathways in kidney cells, including the NLRP3 inflammasome and IL-6/JAK/STAT3 signaling pathway, while promoting autophagy, a cellular cleaning process. For patients with high uric acid levels or early kidney problems, this research suggests that electroacupuncture may offer a complementary treatment option to help protect kidney function and reduce inflammation. If you're considering acupuncture for metabolic or kidney conditions, seek treatment from a licensed acupuncturist with experience in these areas.

This study evaluated electroacupuncture at BL23 for hyperuricemia-induced nephritis in mice treated with potassium oxonate (500 mg/kg) and adenine (100 mg/kg). Daily EA administration significantly reduced serum uric acid, creatinine, and blood urea nitrogen while decreasing urinary protein and increasing creatinine excretion. Single-cell RNA sequencing revealed EA suppressed the NLRP3 inflammasome complex and IL-6/JAK/STAT3 signaling pathway in renal tissue. Western blot analysis confirmed EA inhibited NLRP3 inflammasome activation through autophagy promotion. Serum inflammatory markers (IL-1β, IL-6, TNF-α) were significantly reduced. The study demonstrates BL23 electroacupuncture exhibits nephroprotective effects through dual mechanisms: inhibiting inflammatory cascades and promoting cellular autophagy. Clinical implications suggest EA at BL23 may serve as an adjunctive intervention for hyperuricemia-associated kidney injury, warranting human clinical trials to establish dosing parameters and treatment duration for optimal therapeutic outcomes in patients with elevated uric acid and early-stage renal dysfunction.
