Characterization of the Phosphorylated Forms and the Phosphorylated Residues of Hepatitis Delta Virus Delta Antigens [PDF]

Journal of Virology, 1999
ABSTRACT Hepatitis delta virus (HDV) replication requires both the cellular RNA polymerase and one virus-encoded protein, small delta antigen (S-HDAg). S-HDAg has been shown to be a phosphoprotein, but its phosphorylation status is not yet clear. In this study, we employed three methods to address this question.

Contribution of endosomal proteins EHD1 and EHD4 to the HIV‐1 replication cycle

The FEBS Journal, EarlyView.
EHD1 and EHD4, two key trafficking proteins, regulate multiple stages of HIV‐1 infection: In producer cells, they help produce fully infectious virus particles, regulate Envelope protein incorporation in a cell‐type‐dependent manner, and limit the accumulation of antiviral IFITM proteins in virions.

Mutational analysis of delta antigen: effect on assembly and replication of hepatitis delta virus [PDF]

Journal of Virology, 1994
Hepatitis delta virus requires a helper function from hepatitis B virus for packaging, release, and infection of hepatocytes. The assembly of large delta antigen (HDAg) is mediated by copackaging with the small surface antigen of hepatitis B virus (HBsAg), and the assembly of small HDAg requires interactions with large HDAg.

Antibiotic‐mediated immune modulation in periodontitis

Periodontology 2000, EarlyView.
Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...

Characterization of RNA-binding domains of hepatitis delta antigen

Journal of General Virology, 1993
Hepatitis delta antigen (HDAg), the only protein encoded by the hepatitis delta virus (HDV), binds specifically genomic and antigenomic strands of the HDV RNA. In a previous study, three recombinant HDAg subdomains were synthesized, covering residues 11 to 78, 79 to 163 and 164 to 212, and only the middle domain was shown to be responsible for the ...

Hepatitis B virus infection with high HBsAg and undetectable DNA levels in untreated blood donors: Viral mechanisms and transfusion safety implications

Transfusion, EarlyView.
Abstract Background Blood donor screening occasionally identifies individuals with high HBV surface antigen (HBsAg) levels despite undetectable or extremely low HBV DNA. Molecular basis and transfusion risk of this discordant profile remain unclear. Study Design and Methods Seventy‐five blood donors with HBsAg >100 IU/mL and undetectable or very low ...

Seroepidemiology of hepatitis B virus in Addis Ababa Ethiopia: transmission patterns and vaccine control [PDF]

, 2003
A community-based seroepidemiological survey of Addis Ababa, Ethiopia was conducted in 1994 to inform on the transmission dynamics and control of hepatitis B virus (HBV) infection.

Cloning and expression of an immunodominant region of the hepatitis delta antigen

Journal of General Virology, 1990
A cDNA clone prepared from hepatitis delta virus (HDV) RNA extracted from human serum was subcloned in the bacterial expression vector pPL31 to produce a fusion protein consisting of the first 98 amino acids of MS2 polymerase and of 64 amino acids from near the N-terminal region of hepatitis delta antigen (HDAg).

HIV Testing and Care Among Publicly Insured Enrollees With Schizophrenia: Is There a Benefit to Dual Eligibility?

Psychiatric Research and Clinical Practice, EarlyView.
Background Patients with schizophrenia experience gaps in the human immunodeficiency virus (HIV) care continuum. We examined the impact of dual enrollment in Medicare upon HIV testing and retention among Medicaid‐enrolled patients with schizophrenia.

Deciphering the Role of Post-Translational Modifications and Cellular Location of Hepatitis Delta Virus (HDV) Antigens in HDV-Mediated Liver Damage in Mice

Viruses
Hepatitis D virus (HDV) infection represents the most severe form of chronic viral hepatitis. We have shown that the delivery of HDV replication-competent genomes to the hepatocytes using adeno-associated virus (AAV-HDV) as gene delivery vehicles offers ...
