Liver macrophages as the key regulators of tissue homeostasis in organ

Abstract

   Introduction. View about hepatic macrophages as key regulators of tissue homeostasis, acting via innate and adaptive immune reactions, stimulated by exogenous and/or endogenous alarm signals of tissue injury or cell stress is substantiated in the review. From one hand, environmental signals determine macrophage polarization and production, but, on the other hand, macrophages affect tissue microenvironment and cells and tissue function at whole.   The review was aimed to provide recent evidence of macrophage role in maintenance of tissue homeostasis in liver.   Materials and Methods. Review is based on the 67 scientific articles, devoted to the study and analysis of macrophage role in the maintenance of tissue homeostasis in liver, found in PubMed database. Most of the analyzed articles (40 from 67) were published in 2017-2023.   Results and Discussion. Information of origin and morpho-functional heterogeneity of hepatic macrophages was summarized in the review.   Conclusion. The information presented in the review allow to conclude that macrophages are key regulators of homeostasis in the liver due to their ability to perceive many endogenous and exogenous signals in tissues and quickly respond to them in the direction of stabilizing the tissue microenvironment.
