Pregnant rhesus macaques were infected with HEV to explore the pathogenesis of genotype 4 HEV infection during pregnancy. Active HEV infections were established with shedding viruses in the feces and blood, and elevated liver enzymes.

A newly-designed water-soluble far-red emitting polymer probe, 19K-6H, with a large Stokes shift, was thus evaluated for the tracking of primary immune CD8 T cells. 19K-6H-labelled primary CD8 T cells were injected to mice in a classical model of immune mediated hepatitis.

Researchers found that decreased tyrosine-protein phosphatase nonreceptor type 13 (PTPN13) expression was associated with hepatitis B virus/hepatitis B x protein. Patients with low PTPN13 expression showed a poor prognosis. Functional assays revealed that PTPN13 inhibited proliferation and tumorigenesis in vitro and in vivo.

Aligos Therapeutics, Inc. announced that the company has received approval for a clinical trial application for a first-in-human Phase Ia/b proof-of-concept clinical trial. Aligos may now commence study ALG-000184-201 to evaluate ALG-000184, a small molecule class II capsid assembly modulator that targets hepatitis B virus capsid assembly as well as the establishment of covalently closed circular DNA.

Researchers studied 76 DAA-treated hepatitis C virus (HCV)-positive patients and 18 non-infected controls. Flow cytometry measured pretreatment frequencies of CD4+PD-1+, CD4+PD-1+Tim-3+ and CD8+PD-1+Tim-3+ T-cells and IL-10 levels measured by ELISA were significantly higher and CD4+PD-1−Tim-3− and CD8+PD-1−Tim-3− T-cells were significantly lower in patients than in controls.
