Insights

Human oncogenic viruses manipulate innate immunity by altering pattern recognition receptor (PRR) signaling, leading to altered interferon responses and promoting tumor development. Understanding these viral pathways is key to targeting cancer therapies.

Area of Science:

  • Virology
  • Immunology
  • Oncology

Background:

  • Human oncogenic viruses (oncoviruses) strategically manipulate host innate immune responses.
  • These viruses alter pattern recognition receptor (PRR) signaling to ensure persistence without complete immune evasion.
  • Such immune reprogramming can lead to altered interferon responses and inflammation, favoring tumor establishment.

Purpose of the Study:

  • To provide a conceptual framework for understanding common viral pathways (convergent) and virus-specific effects (divergent) of oncovirus-innate immunity interactions.
  • To review the impact of oncoviruses like HPV, HBV, and EBV on the tissue microenvironment (TME) and tumorigenesis.
  • To propose a spatial-temporal model of PRR modulation and identify knowledge gaps for therapeutic targeting.

Main Methods:

  • Review of existing literature on oncovirus-innate immunity interactions.
  • Focus on common oncoviruses: human papillomavirus (HPV), hepatitis B virus (HBV), and Epstein-Barr virus (EBV).
  • Conceptualization of a spatial-temporal model for PRR modulation.

Main Results:

  • Oncoviruses selectively modulate PRR signaling to control immune responses.
  • Viral manipulation leads to altered interferon production and inflammatory signaling, contributing to tumorigenesis.
  • Distinct viral strategies result in both common (convergent) and specific (divergent) effects on the TME.

Conclusions:

  • Oncovirus-induced innate immune reprogramming plays a critical role in shaping the TME and promoting cancer.
  • A proposed model distinguishes convergent interferon dampening from divergent microenvironmental reprogramming.
  • Targeting innate sensing pathways presents a potential therapeutic strategy against virus-associated cancers.

Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms 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...

Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

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...
