Insights

Oncolytic virus (OV) therapy is advancing, with modifications to viral proteins enhancing cancer cell targeting. Understanding virus-receptor interactions aids in developing OVs for improved tumor specificity and broader cancer treatment applications.

Area of Science:

  • Oncology
  • Virology
  • Structural Biology

Background:

  • Oncolytic virotherapy utilizes viruses to selectively target and destroy cancer cells.
  • Modifying viral surface proteins is a key strategy for enhancing oncolytic virus (OV) efficacy and specificity.
  • Structural insights into virus-receptor interactions are crucial for understanding OV tropism.

Purpose of the Study:

  • To review strategies for developing novel oncolytic viruses (OVs) for cancer therapy.
  • To discuss the role of structural knowledge in understanding and engineering OV tumor targeting.
  • To explore repurposing OVs through modifications for improved cancer treatment.

Main Methods:

  • Review of current literature on oncolytic virotherapy.
  • Analysis of structural data on OV-receptor interactions.
  • Discussion of viral protein modification techniques for cancer targeting.

Main Results:

  • Detailed structural understanding of OV-natural receptor interactions informs tumor specificity.
  • Receptor re-targeting strategies can broaden tumor tropism or enhance selectivity.
  • Viral envelope and coat protein modifications are effective for repurposing OVs.

Conclusions:

  • Structural biology provides critical insights for advancing oncolytic virus therapy.
  • Engineering OVs through protein modification offers promising avenues for cancer treatment.
  • Targeted modifications can optimize OV tropism for enhanced anti-cancer efficacy.

Receptor-mediated Endocytosis01:20

Receptor-mediated Endocytosis

Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

Viral Structure00:56

Viral Structure

Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

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...

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Leaky Scanning02:28

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...
