Update on HHV-8-Associated Malignancies.
Current Infectious Disease Reports
|May 13, 2010
Summary
Human herpesvirus 8 (HHV-8) drives Kaposi's sarcoma and related cancers. Research explores HHV-8 transmission, molecular biology, and targeted therapies, seeking better treatments for these neoplasms.
Area of Science:
- Oncology
- Virology
- Molecular Biology
Background:
- Human herpesvirus 8 (HHV-8) is linked to Kaposi's sarcoma (KS) and lymphoproliferative disorders.
- KS remains a significant malignancy in HIV-infected individuals, despite advances in antiretroviral therapy.
- HHV-8 uses molecular mimicry to activate cellular pathways and evade immune responses, contributing to tumorigenesis.
Purpose of the Study:
- To review recent advancements in understanding HHV-8.
- To summarize developments in HHV-8 transmission, molecular biology, and treatment strategies.
- To highlight ongoing research into prognostic factors for HHV-8-related neoplasms.
Main Methods:
- Literature review of recent scientific publications.
- Synthesis of information on HHV-8 molecular pathology and tumorigenesis.
- Analysis of current therapeutic strategies and their efficacy.
Main Results:
- HHV-8 oncogenesis involves viral proteins mimicking cellular functions, activating signaling cascades.
- Multiple targeted therapies show activity against HHV-8-related cancers but are not curative.
- Research is actively identifying prognostic factors for these neoplasms.
Conclusions:
- Understanding HHV-8 molecular mimicry has informed targeted therapeutic development.
- Current treatments offer activity but not a cure for HHV-8-associated malignancies.
- Continued research into transmission, biology, and prognostication is crucial for improving patient outcomes.

01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
01:51Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

01:03Rous 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...

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...
