A new era in the treatment of kidney diseases: NLRP3 inflammasome and cytokine-targeted therapies

Abstract

The kidneys are crucial for filtering blood, managing overall body water, electrolyte, and acid-base balance, and regulating blood pressure. They remove metabolic waste products, toxins, and drugs. In addition, they limit inflammation by clearing cytokines and reduce immune cell activation by removing bacterial components. Dendritic cells (DCs) in the kidney maintain peripheral tolerance. About 85% of filtered water is reabsorbed by the proximal tubule, exposing distal nephron cells to high concentrations of low molecular weight antigens. These antigens are captured by DCs, helping to inactivate potentially autoreactive T cells and maintain tolerance to circulating antigens. In kidney failure, immune function is severely compromised due to the retention of toxins and cytokines, which activate immune cells and increase systemic inflammation. The kidneys are also vulnerable to immune-mediated diseases. Loss of immune homeostasis, characterized by over- or under-activity of the immune response, can adversely affect kidney function. With advances in immunology and cellular biology, biologic therapies targeting various pathways involved in the pathophysiology of kidney diseases are being developed. In this review, the immunologic aspects of kidney diseases and focus on cytokine-based therapies that may hold promise for the treatment of kidney diseases in the future will be presented.

Keywords: Cytokine-targeted therapies; Kidney diseases; NLRP3 inflammasome.
