CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

Advanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

Chronic Viral Hepatitis: Etiology, Pathogenesis of Liver Damage and Mechanisms of Persistence [PDF]

, 2004
Chronic hepatotropic viruses commonly evade the antiviral defence systems of the body and cause a long - lasting persistent infection. The prolonged nature of the infection ensures that every infected person has ample opportunity to transmit the virus to

p16Ink4a‐Positive Hepatocytes Drive Liver Fibrosis Through Activation of LIFR Family Pathway

Advanced Science, EarlyView.
This study found that, following the long‐term CCl4 treatment, p16high hepatocytes appeared in zone 3, spatially co‐localizing with fibrotic areas. A specific cluster of p16high hepatocytes upregulated CTF1/LIF expression which induced HSC activation and further liver fibrosis, as revealed by single cell transcriptomic analysis.

Initiation of hepatitis C virus infection is dependent on cholesterol and cooperativity between CD81 and scavenger receptor B type I. [PDF]

, 2006
In the past several years, a number of cellular proteins have been identified as candidate entry receptors for hepatitis C virus (HCV) by using surrogate models of HCV infection.

Nuclear Factor I‐B Delays Liver Fibrosis by Inhibiting Chemokine Ligand 5 Transcription

Advanced Science, EarlyView.
This study identifies the transcription factor Nuclear Factor I‐B (NFIB) as a key suppressor of liver fibrosis. NFIB expression declines during hepatic stellate cell activation, and its overexpression reduces fibrosis in mice models. The mechanism involves NFIB directly repressing chemokine C─C motif ligand 5 (CCL5), thereby alleviating oxidative ...

Requirement of Activation for Hepatitis B Virus Infection [PDF]

, 2007
Although _in vitro_ models of human hepatitis B virus replication are established, so far none could approximate infection efficiency as expected from _in vivo_ observations.

Pathogenesis of hepatitis B virus infection [PDF]

World Journal of Gastroenterology, 2007
Infection with hepatitis B virus (HBV) leads to a wide spectrum of clinical presentations ranging from an asymptomatic carrier state to self-limited acute or fulminant hepatitis to chronic hepatitis with progression to cirrhosis and hepatocellular carcinoma. Infection with HBV is one of the most common viral diseases affecting man.

Inhibition of SLC11A1‐Mediated Lysosomal Iron Accumulation in Microglia Promotes Repair Following White Matter Stroke

Advanced Science, EarlyView.
Genetic and pharmacological inhibition of SLC11A1 functioning as an H+/Fe2+ antiporter–mediated lysosomal iron accumulation in microglia promotes lysosomal lumen acidification, increases CTSD expression, enhances lysosomal myelin debris uptake and degradation, and promotes repair following white matter stroke. ABSTRACT White matter stroke (WMS) results

Host–virus interactions in hepatitis B virus infection [PDF]

Current Opinion in Immunology, 2015
Hepatitis B virus (HBV) is a noncytopathic, hepatotropic, double-stranded DNA virus that causes acute and chronic hepatitis. Although HBV does not induce a measurable innate immune response in the infected liver, the outcome of infection is determined by the kinetics, breadth, vigor, trafficking, and effector functions of HBV-specific adaptive T cell ...

Cleavage‐Resistant CYLD Protects Against Autoimmune Hepatitis

Advanced Science, EarlyView.
Proteolytic cleavage of the deubiquitinase CYLD emerges as a critical driver of autoimmune hepatitis. TNFα‐induced CYLD loss in macrophages amplifies S100A9‐triggered MAPK activation, leading to excessive chemokine production and hepatic inflammation. Pharmacological inhibition of MEK signaling effectively attenuates experimental disease, highlighting ...
