Resident immune cell neighborhoods associate with protein kinase pRIPK3 and fatty acid ligase FACL4 expression during cell injury in ANCA associated vasculitis and lupus nephritis

Study limitation reported by the research below: “Sample size is very small (n=5 per group); findings are explicitly hypothesis-generating and should not be interpreted as definitive. Reference tissue is nephrectomy-derived non-tumor kidney, which may differ from truly healthy kidney parenchyma. Study design is observational with no longitudinal or interventional component; causal inference is not possible.”
