| contents | Abstract The kidney is traditionally conceptualized as a homeostatic filtration organ regulating fluid balance, electrolyte composition, and metabolic waste. Recent advances in psychoneuroimmunology and stress physiology, however, indicate that renal tissue is deeply embedded within systemic neuro-endocrine-immune networks. Chronic psychosocial stress, through sustained activation of the hypothalamic–pituitary–adrenal (HPA) axis and sympathetic nervous system, generates a persistent inflammatory milieu that directly alters glomerular permeability, tubular transport, and microvascular integrity. This theoretical study proposes a reconceptualization of the kidney as a central neuro-inflammatory regulator that encodes cumulative stress exposure and allostatic load, rather than merely a passive target of metabolic dysregulation. Using an integrative conceptual analysis, findings from nephrology, stress neurobiology, and immunology are synthesized to construct a unified model explaining how narrative-level chronic stress (sustained cognitive–emotional burden) is transduced into renal microinflammation and progressive functional decline. A novel framework, the Neuro-Renal Allostatic Load Model (NRALM), is introduced. The model demonstrates that prolonged HPA-axis activation, sympathetic overdrive, and cytokine signaling converge on the renal microcirculation, producing endothelial dysfunction, oxidative stress, and fibrotic signaling that accelerate chronic kidney disease (CKD) independent of classical metabolic risk factors. The kidney should be understood as a dynamic organ of neuro-inflammatory regulation, structurally and functionally shaped by chronic stress physiology. This perspective offers a new epistemological layer for nephrology and provides a theoretical basis for integrating psychophysiological stress assessment into renal risk stratification and disease progression models. |
