Systematic Review Links Lysosomal Pathways to Autoimmune Kidney Disease Progression

This systematic review examines the role of lysosomal pathways in autoimmune kidney diseases, including lupus nephritis and ANCA-associated vasculitis. The authors synthesize evidence from basic and translational studies, focusing on how lysosomal functions regulate the initiation and progression of renal autoimmunity.

Key findings indicate that lysosomes serve as checkpoints through mechanisms involving autoantigen processing and presentation, immune cell activation, breakdown of tolerance, and metabolic-immune crosstalk. These processes are implicated in the pathogenesis of autoimmune kidney diseases, suggesting that lysosomal dysfunction may contribute to disease onset and progression.

The review identifies targeting lysosomal pathways as a potential novel therapeutic strategy. However, the evidence is derived from preclinical and mechanistic studies; no clinical trials or patient-level data are reported. The authors do not discuss specific limitations, but the absence of pooled effect sizes, sample sizes, and comparator data limits the strength of conclusions.

For clinicians, this review provides a conceptual framework for understanding lysosomal contributions to renal autoimmunity. While the therapeutic potential is intriguing, direct clinical applicability remains uncertain until further research, including human studies, validates these mechanisms and explores targeted interventions.
