The pathophysiology of MASLD: an immunometabolic perspective.
Introduction: Metabolic-associated liver diseases have emerged pandemically across the globe and are clinically related to metabolic disorders such as obesity and type 2 diabetes. The new nomenclature and definition (i.e. metabolic dysfunction-associated steatotic liver disease - MASLD; metabolic dysfunction-associated steatohepatitis - MASH) reflect the nature of these complex systemic disorders, which are characterized by inflammation, gut dysbiosis and metabolic dysregulation. In this review, we summarize recent advantages in understanding the pathophysiology of MASLD, which we parallel to emerging therapeutic concepts.
Areas covered: We summarize the pathophysiologic concepts of MASLD and its transition to MASH and subsequent advanced sequelae of diseases. Furthermore, we highlight how dietary constituents, microbes and associated metabolites, metabolic perturbations, and immune dysregulation fuel lipotoxicity, hepatic inflammation, liver injury, insulin resistance, and systemic inflammation. Deciphering the intricate pathophysiologic processes that contribute to the development and progression of MASLD is essential to develop targeted therapeutic approaches to combat this escalating burden for health-care systems.
Expert opinion: The rapidly increasing prevalence of metabolic dysfunction-associated steatotic liver disease challenges health-care systems worldwide. Understanding pathophysiologic traits is crucial to improve the prevention and treatment of this disorder and to slow progression into advanced sequelae such as cirrhosis and hepatocellular carcinoma.
期刊介绍:
Expert Review of Clinical Immunology (ISSN 1744-666X) provides expert analysis and commentary regarding the performance of new therapeutic and diagnostic modalities in clinical immunology. Members of the International Editorial Advisory Panel of Expert Review of Clinical Immunology are the forefront of their area of expertise. This panel works with our dedicated editorial team to identify the most important and topical review themes and the corresponding expert(s) most appropriate to provide commentary and analysis. All articles are subject to rigorous peer-review, and the finished reviews provide an essential contribution to decision-making in clinical immunology.
Articles focus on the following key areas:
• Therapeutic overviews of specific immunologic disorders highlighting optimal therapy and prospects for new medicines
• Performance and benefits of newly approved therapeutic agents
• New diagnostic approaches
• Screening and patient stratification
• Pharmacoeconomic studies
• New therapeutic indications for existing therapies
• Adverse effects, occurrence and reduction
• Prospects for medicines in late-stage trials approaching regulatory approval
• Novel treatment strategies
• Epidemiological studies
• Commentary and comparison of treatment guidelines
Topics include infection and immunity, inflammation, host defense mechanisms, congenital and acquired immunodeficiencies, anaphylaxis and allergy, systemic immune diseases, organ-specific inflammatory diseases, transplantation immunology, endocrinology and diabetes, cancer immunology, neuroimmunology and hematological diseases.
