Insights

Mutations in the Hepatitis B virus (HBV) S gene were identified in most children with HBV-associated glomerulonephritis (HBV-GN). These genetic changes, particularly those affecting phosphorylation sites, may contribute to the development of HBV-GN.

Area of Science:

  • Virology
  • Nephrology
  • Genetics

Context:

  • Hepatitis B virus-associated glomerulonephritis (HBV-GN) is an immune complex-mediated kidney disease.
  • Understanding the genetic basis of HBV-GN is crucial for developing targeted therapies.

Purpose:

  • This study aimed to identify mutations in the Hepatitis B virus (HBV) S gene in children diagnosed with HBV-GN.
  • The research also investigated the impact of these mutations on protein structure and potential pathogenic mechanisms.

Summary:

  • Serum HBV DNA from 53 children (30 with HBV-GN, 5 with HBV-carrying nephrosis, 18 HBV carriers) was analyzed for HBV S gene mutations using PCR and sequencing.
  • Seventy percent of HBV-GN patients exhibited single nucleotide changes in the HBV S gene, with 76.2% resulting in amino acid substitutions.
  • Most amino acid substitutions involved threonine, serine, and tyrosine, which are potential phosphorylation sites, suggesting a role in HBV-GN pathogenesis.

Impact:

  • Identifies specific HBV S gene mutations associated with glomerulonephritis in children.
  • Highlights the potential role of altered HBV protein phosphorylation in the pathogenesis of HBV-GN.
  • Provides insights for future research into diagnostic markers and therapeutic strategies for HBV-GN.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
