Abstract:
DNA oncoviruses represent an intriguing subject due to their involvement in oncogenesis. These viruses have evolved mechanisms to manipulate the host immune response, facilitating their persistence and actively contributing to carcinogenic processes. This paper describes the complex interactions between DNA oncoviruses and the innate immune system, with a particular emphasis on the cGAS-STING pathway. Exploring these interactions highlights that DNA oncoviruses strategically target and subvert this pathway, exploiting its vulnerabilities for their own survival and proliferation within the host. Understanding these interactions lays the foundation for identifying potential therapeutic interventions. Herein, we sought to contribute to the ongoing efforts in advancing our understanding of the innate immune system in oncoviral pathogenesis.
Insights
DNA oncoviruses manipulate host immunity, targeting the cGAS-STING pathway for survival. Understanding these interactions is key to developing new therapies against virus-induced cancers.
Area of Science:
- Immunology
- Virology
- Oncology
Background:
- DNA oncoviruses are implicated in human cancers.
- These viruses possess mechanisms to evade host immune surveillance.
- The innate immune system plays a critical role in controlling viral infections.
Purpose of the Study:
- To elucidate the intricate interplay between DNA oncoviruses and the innate immune system.
- To specifically investigate the targeting of the cGAS-STING pathway by DNA oncoviruses.
- To identify potential therapeutic strategies by understanding these viral-host interactions.
Main Methods:
- Review of existing literature on DNA oncoviruses and innate immunity.
- Analysis of molecular mechanisms employed by viruses to subvert immune pathways.
- Focus on the cyclic GMP-AMP synthase (cGAMP) -stimulator of interferon genes (STING) signaling cascade.
Main Results:
- DNA oncoviruses actively manipulate host immune responses.
- These viruses strategically target and exploit the cGAS-STING pathway.
- Viral subversion of cGAS-STING facilitates persistence and oncogenesis.
