Inhibition of replication of hepatitis B virus using transcriptional repressors that target the viral DNA

BMC Infectious Diseases, 2019
Background Chronic infection with hepatitis B virus (HBV) is a serious global health problem. Persistence of the virus occurs as a result of stability of the replication intermediate comprising covalently closed circular DNA (cccDNA).

The redox transformations and nucleophilic replacements as possible metabolic reactions of the drug “Triazaverin”. The chemical modeling of the metabolic processes [PDF]

, 2015
As a model of metabolic transformations of antiviral drug “Triazaverin” and its analogues‑2-alkylthio‑6-nitro‑1,2,4-triazolo[5,1-c][1,2,4]triazine‑7-ones 1a-d examined the oxidation of alkylthio groups to the corresponding sulfoxides 2a-d and sulfones 3a-

Type I Interferon Signaling Augments Autoimmunity in Neuromyelitis Optica Spectrum Disorder

Advanced Science, EarlyView.
The cGAS‐STING innate immune pathway is excessively activated both in peripheral monocytes and CNS microglia in patients with NMOSD, leading to an overproduction of IFN‐I. IFN‐I subsequently acts on AQP4‐specific autoreactive T cells. Blocking this pathway may offer novel therapeutic options for individuals with NMOSD.

The CXCL10‐CXCR3 Axis Induces Tumor‐Associated Neutrophils to Interfere with CTLs‐Mediated Antitumor Activity in EBV‐Associated Epithelial Cancers

Advanced Science, EarlyView.
Compared with EBV‐negative epithelial cancer cells, EBV‐associated epithelial cancer cells exhibit enhanced secretion of chemokines, including CXCL10 and CCL5, to attract neutrophils. Via the CXCL10‐CXCR3 axis‐mediated positive feedback loop, neutrophils within EBV‐associated epithelial cancer cells are induced to form abundant NETs, which facilitate ...

Efficacious control of cytomegalovirus infection after long-term depletion of CD8+ T lymphocytes [PDF]

, 1990
Although the relative contribution of different immune effector functions to clearing tissues of cytomegalovirus is controversial, the contribution of CD8+ T lymphocytes has generally been accepted as essential. In this report, we show that under certain

Hepatitis E Virus ORF1 Polyprotein Harbors a Pocket‐Like Cavity That Is Vital for Virus Replication and Represents a Novel Antiviral Target

Advanced Science, EarlyView.
Within the hepatitis E virus (HEV) ORF1 polyprotein, the X domain interacts with viral RNA‐dependent RNA polymerase (RdRp), forming a functional “pocket‐like” cavity (PC) that is crucial for viral replication. Structure‐based screening, surface plasmon resonance (SPR) assays, and HEV model validation collectively identify saikosaponin D and ...

Mechanistic insights into post-translational modifications in hepatic fibrosis: pathogenic roles and therapeutic potentials

Journal of Translational Medicine
Hepatic fibrosis, a critical progression in liver disease, has been widely studied. While the activation of stellate cells and the accumulation of extracellular matrix components are recognized as key mechanisms, additional research is necessary to ...

Therapeutic mitigation of measles-like immune amnesia and exacerbated disease after prior respiratory virus infections in ferrets

Nature Communications
Measles cases have surged pre-COVID-19 and the pandemic has aggravated the problem. Most measles-associated morbidity and mortality arises from destruction of pre-existing immune memory by measles virus (MeV), a paramyxovirus of the morbillivirus genus ...

Structure-function analysis of the ATPase domain of African swine fever virus topoisomerase

mBio
Type II topoisomerase utilizes the energy from ATP hydrolysis to alter DNA topology during genome replication and transcription. The ATPase domain of this enzyme is required for ATP hydrolysis and plays a crucial role in coupling DNA binding and ATP ...
