Unraveling the proteomic landscape of fibrosis in lupus nephritis through CI-based analysis.

In conclusion, this study establishes molecular subgroups based on the CI score, providing novel insights into the molecular mechanisms governing chronicity in the kidneys of diverse LN patients. Key Points • Fibrosis is a fundamental and characteristic pathological process underlying the NIH-CI in LN. • Different EMT status presented variant clinical characteristics, immune features in LN.
