Effect of QingreHuoxue formula on Th17 cells and Tregs in mice with idiopathic membranous nephropathy

Objectives: This study aimed to evaluate the therapeutic effect of the QingreHuoxue formula on mice with Idiopathic Membranous Nephropathy (IMN) and its impact on Th17 cells and Tregs.

Methods: A mouse model of IMN was established, and the mice were treated with traditional Chinese medicine, western medicine, or a combination of both. The efficacy and immunomodulatory effects of the QingreHuoxue formula were evaluated by examining renal pathology, urinary protein levels, peripheral blood Th17 and Treg cell counts, and comparing the expression levels of IL-17 and transforming growth factor-β1 in renal tissues.

Results: Compared to the untreated IMN model group, the IMN mice treated with TCM, western medicine, or the combination showed significant improvements in proteinuria, renal pathology, peripheral T lymphocyte counts, and IL-17 expression in renal tissues. Notably, the group treated with a combination of Chinese and western medicine exhibited better outcomes than the group treated with western medicine alone.

Conclusions: The QingreHuoxue formula was effective in reducing proteinuria, modulating T cell immune function, and protecting renal tissue in mice with IMN.
