Background: Bone marrow-derived macrophages (BMDMs) regulate hepatic progenitor cells (HPCs) differentiation, potentially via the Wnt signaling pathway. While M1-polarized BMDMs (M1-BMDMs) exert anti-fibrotic effects in the liver, Wnt5a is implicated in fibrosis progression. The specific influence of Wnt5a levels within M1-BMDMs on HPCs fate and cirrhosis development remains unclear. This study aimed to elucidate the relationship between M1-BMDM-derived Wnt5a and HPCs differentiation during cirrhosis progression.
Methods: First, Wnt5a protein expression was assessed in liver biopsy tissues from patients with hepatitis B-associated liver fibrosis. Second, cirrhosis was induced in rats using CCl/2-AAF. In week 9, rats received intravenous injections of M1-BMDMs with Wnt5a knockdown (M1-BMDM ) or overexpression (M1-BMDM ); peripheral BMDMs recruitment was blocked using a CCR2 inhibitor. Fibrosis progression, ductular reaction (DR), and HPC differentiation were evaluated. In vitro, WB-F344 cells subjected to 2 (2) knockdown (WB-F344 ) or overexpression (WB-F344 ) were cultured with conditioned medium from M1-BMDM (CM ) or M1-BMDM (CM ).
Results: In patients with hepatitis B-related fibrosis, hepatic Wnt5a expression increased progressively with METAVIR fibrosis grade. In the rat cirrhosis model, M1-BMDMs attenuated fibrosis, whereas M1-BMDMs exacerbated it. Mechanistically, in vivo injection of M1-BMDMs significantly inhibited HPCs differentiation into biliary epithelial cells (BECs), while M1-BMDM promoted this differentiation. In vitro, CM inhibited the differentiation of WB-F344 cells into BECs; this inhibition was potentiated by knockdown in WB-F344 cells but abrogated by overexpression. Conversely, under CM conditions, WB-F344 cells exhibited increased cholangiocytic differentiation, an effect largely negated by knockdown.
Conclusions: M1-BMDMs demonstrated superior therapeutic efficacy against cirrhosis compared to unmodified M1-BMDMs. Wnt5a/Fzd2 signaling mediated the crosstalk between M1-BMDMs and HPCs, revealing a novel therapeutic target for cirrhosis treatment.

Unlabelled: Drug-induced liver injury (DILI) is a major cause of acute liver failure and drug withdrawal. Cytochrome P450 (CYP) 2E1 is involved in the metabolism of several drugs, and can induce liver injury through the production of toxic metabolites and the generation of reactive oxygen species. This study aimed to elucidate the role of Wnt/β-catenin signaling in CYP2E1 regulation for drug-induced hepatotoxicity.
