Abstract
Introduction: The liver is a central metabolic organ, but is also hosting a unique immune microenvironment to sustain homeostasis and proper defense measures against injury threats in healthy individuals. Liver macrophages, mostly represented by the tissue-resident Kupffer cells and bone marrow- or monocyte-derived macrophages, are intricately involved in various aspects of liver homeostasis and disease, including tissue injury, inflammation, fibrogenesis and repair mechanisms.
Areas covered: We review recent findings on defining the liver macrophage landscape and their functions in liver diseases with the aim of highlighting potential targets for therapeutic interventions. A comprehensive literature search in PubMed and Google Scholar was conducted to identify relevant literature up to date.
Expert opinion: Liver macrophages orchestrate key homeostatic and pathogenic processes in the liver. Thus, targeting liver macrophages represents an attractive strategy for drug development, e.g. to ameliorate liver inflammation, steatohepatitis or fibrosis. However, translation from fundamental research to therapies remains challenging due to the versatile nature of the liver macrophage compartment. Recent and major technical advances such as single-cell and spatially-resolved omics approaches deepened our understanding of macrophage biology at a molecular level. Yet, further studies are needed to identify suitable, etiology- and stage-dependent strategies for the treatment of liver diseases.
期刊介绍:
The enormous health and economic burden of gastrointestinal disease worldwide warrants a sharp focus on the etiology, epidemiology, prevention, diagnosis, treatment and development of new therapies. By the end of the last century we had seen enormous advances, both in technologies to visualize disease and in curative therapies in areas such as gastric ulcer, with the advent first of the H2-antagonists and then the proton pump inhibitors - clear examples of how advances in medicine can massively benefit the patient. Nevertheless, specialists face ongoing challenges from a wide array of diseases of diverse etiology.
