Insights

Oncolytic virus therapy, including adenoviruses, is advancing with staged clinical trials and new virus platforms. Future developments focus on improving systemic delivery and efficacy for metastatic cancers.

Area of Science:

  • Oncolytic virotherapy
  • Cancer gene therapy

Background:

  • Adenoviruses like Onyx-015 and H101 paved the way for oncolytic virus development.
  • Early clinical trials demonstrated the success of a staged approach, from intratumoral injection to combination therapies.

Purpose of the Study:

  • To review the evolution of oncolytic virus development, focusing on adenoviruses.
  • To discuss the strategies for second-generation oncolytic viruses aiming for enhanced systemic delivery and efficacy.

Main Methods:

  • Review of clinical development pathways for adenoviral oncolytic viruses.
  • Analysis of strategies for engineering new oncolytic virus platforms.

Main Results:

  • Staged clinical development is a judicious approach for oncolytic viruses.
  • Second-generation viruses aim for improved tumor cell killing, intravenous delivery, and intratumoral spread.

Conclusions:

  • Improving efficacy in metastatic cancer requires enhanced tumor cell killing and systemic delivery.
  • Tumor specificity of oncolytic viruses is complex and may involve multiple factors beyond a single predictive pathway.

Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...

Introduction to Virus

Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...

Inhibitors Of Virion Release

Viral replication and dissemination rely on efficient mechanisms for host cell entry, genome replication, assembly, and release. Influenza viruses, such as types A and B, are negative-sense single-stranded RNA viruses with a segmented genome, that depend on two critical surface glycoproteins to carry out these processes: hemagglutinin (HA) and neuraminidase (NA). HA initiates infection by binding to sialic acid residues on the surface of host epithelial cells, facilitating receptor-mediated...
Viral Replication: Lytic Cycle01:20

Viral Replication: Lytic Cycle

Bacteriophages, or phages, are viruses that specifically infect bacteria. Among them, T-even bacteriophages, such as T4, exhibit a well-characterized lytic replication cycle in Escherichia coli (E. coli). This process ensures the rapid proliferation of the virus while ultimately leading to the destruction of the bacterial host.Attachment and DNA InjectionThe infection process begins with the recognition and binding of the T4 phage to the E. coli cell surface. Tail fibers of the phage...

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...
