Neutrophils in Liver Diseases: Functions and Challenging Therapies

Abstract This review explores the pivotal and multifaceted roles of neutrophils in the context of liver pathophysiology. Although traditionally recognized as primary effectors of antibacterial immunity, recent evidence reveals that these abundant leukocytes function as complex regulators in the development and progression of various hepatic conditions. Neutrophils act as double-edged swords: they serve as critical instigators of inflammatory cascades and fibrogenesis, yet simultaneously provide essential contributions to immune defense and the orchestration of tissue repair. This paper synthesizes current research regarding neutrophil behavior within diverse hepatic microenvironments and evaluates their specific contributions to disease resolution versus exacerbation. Furthermore, we deliberate on the emerging potential of targeting neutrophil-specific pathways as a novel therapeutic strategy for liver diseases. Understanding these intricate balances is essential for transitioning from broad anti-inflammatory approaches to precise, neutrophil-modulated interventions. In conclusion, given their status as a dynamic research hotspot, a deeper mechanical understanding of neutrophil functions is imperative for the development of targeted clinical treatments for liver disorders.
