Insights

Oncolytic viruses (OVs) can eliminate cancer by infecting cells. New strategies leverage the tumor microenvironment to enhance OV effectiveness against malignancies.

Area of Science:

  • Oncology
  • Virology
  • Immunology

Background:

  • Oncolytic viruses (OVs) are engineered to infect and lyse cancer cells.
  • The tumor microenvironment (TME) can hinder OV delivery and efficacy.
  • OVs can also exploit TME features for therapeutic benefit.

Purpose of the Study:

  • To discuss strategies that enhance OV therapy by manipulating the TME.
  • To explore the complex interactions between OVs and the host-TME.
  • To improve OV-mediated anticancer activity.

Main Methods:

  • Literature review of OV mechanisms and TME interactions.
  • Analysis of strategies to enhance OV toxicity within the TME.
  • Discussion of host-tumour interactions.

Main Results:

  • OVs can be designed to overcome TME barriers.
  • The TME can be altered by OVs to potentiate anticancer effects.
  • Multifaceted interactions between OVs and the TME enhance therapeutic outcomes.

Conclusions:

  • Strategies capitalizing on OV-TME interactions can improve oncolytic virotherapy.
  • Understanding and manipulating the TME is crucial for effective OV treatment.
  • Enhanced OV toxicity to tumors is achievable through TME modulation.

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
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...

Cancer Therapies02:49

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
