Traditional Chinese Medicine in Treating IgA Nephropathy: From Basic Science to Clinical Research

IgA nephropathy (IgAN) is a major cause of chronic kidney disease (CKD) and end-stage renal disease worldwide. Currently, clinical interventions for IgAN are limited, and many patients seek out alternative therapies such as traditional Chinese medicine (TCM). In the last several years, TCM has accumulated ample application experiences and achieved favorable clinical effects. This article summarizes high-quality research from basic science to clinical applications aimed to provide more evidence-based medicine proof for the clinical treatment of IgAN. In summary, qi and yin deficiency accounted for the largest proportion in IgAN patients, and the treatment of IgAN should be based on supplementing qi and nourishing yin. Further, for patients with severe IgAN, the treatment combination of Chinese and Western medicines is better than pure Chinese medicine or hormone therapy. In addition, the pharmacological mechanism of Chinese herbal medicines is mostly based on restoring the immune function, relieving the inflammation damage, and inhibiting proliferation of the glomerular mesangial cells.

CILAIR-Based Secretome Analysis of Obese Visceral and Subcutaneous Adipose Tissues Reveals Distinctive ECM Remodeling and Inflammation Mediators

In the context of obesity, strong evidences support a distinctive pathological contribution of adipose tissue depending on its anatomical site of accumulation. Therefore, subcutaneous adipose tissue (SAT) has been lately considered metabolically benign compared to visceral fat (VAT), whose location is associated to the risk of developing cardiovascular disease, insulin resistance, and other associated comorbidities. Under the above situation, the chronic local inflammation that characterizes obese adipose tissue, has acquired a major role on the pathogenesis of obesity. In this work, we have analyzed for the first time human obese VAT and SAT secretomes using an improved quantitative proteomic approach for the study of tissue secretomes, Comparison of Isotope-Labeled Amino acid Incorporation Rates (CILAIR). The use of double isotope-labeling-CILAIR approach to analyze VAT and SAT secretomes allowed the identification of location-specific secreted proteins and its differential secretion. Additionally to the very high percentage of identified proteins previously implicated in obesity or in its comorbidities, this approach was revealed as a useful tool for the study of the obese adipose tissue microenvironment including extracellular matrix (ECM) remodeling and inflammatory status. The results herein presented reinforce the fact that VAT and SAT depots have distinct features and contribute differentially to metabolic disease.
