Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

6.7K
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...

Rous Sarcoma Virus (RSV) and Cancer

6.1K
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...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

1.8K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Area of Science:

  • Oncology
  • Virology
  • Hematology

Background:

  • Human T-cell leukemia virus type 1 (HTLV-1) is a retrovirus linked to adult T-cell leukemia/lymphoma (ATL).
  • ATL affects approximately 5% of infected individuals after a long latency period.
  • ATL presents in various subtypes (smoldering, chronic, lymphoma, acute) with distinct prognoses.

Purpose of the Study:

  • To review the key characteristics and pathogenesis of ATL.
  • To summarize current therapeutic approaches for ATL.
  • To discuss future perspectives and novel treatments for ATL.

Main Methods:

  • Literature review of HTLV-1 and ATL.
  • Analysis of clinical classifications and subtypes of ATL.
  • Compilation of data on existing and emerging ATL treatments.

Main Results:

  • ATL development involves a multi-step process following HTLV-1 infection.
  • Treatment efficacy varies by ATL subtype, with options ranging from watchful waiting to stem cell transplantation.
  • Survival rates differ significantly across ATL subtypes.

Conclusions:

  • ATL is a complex malignancy with a long preclinical phase.
  • Multidisciplinary treatment strategies are essential for managing ATL.
  • Ongoing research into targeted therapies and immunotherapy holds promise for improving ATL outcomes.
