Summary
Oncolytic adenoviruses are engineered viruses that target cancer cells. Current research focuses on combining them with immune checkpoint inhibitors for improved cancer therapy, though immune system interactions require further study.
Area of Science:
- Oncolytic virotherapy
- Cancer immunology
- Viral gene therapy
Background:
- Adenoviruses were early candidates for oncolytic virus therapy.
- The field has progressed, with herpesvirus-based Talimogene laherparepvec approved in 2015.
- Recombinant adenoviruses represent a significant portion of ongoing clinical trials for oncolytic agents.
Purpose of the Study:
- To review current oncolytic adenovirus strategies in clinical trials.
- To explore how viral mutational backgrounds may affect efficacy in oncolysis and immunotherapy.
- To highlight the understudied interactions between adenoviruses and the immune system.
Main Methods:
- Review of clinical trial strategies for oncolytic adenoviruses.
- Analysis of viral factors influencing innate and adaptive immunity.
- Speculation on the impact of mutational backgrounds on therapeutic outcomes.
Main Results:
- Oncolytic adenoviruses are widely used in clinical trials, particularly in combination with immune checkpoint inhibitors (ICIs).
- Early combination studies with ICIs show promising results.
- Existing engineering strategies often prioritize tumor cell replication over immune system modulation.
Conclusions:
- Further research into adenovirus-immune system interactions is crucial for designing next-generation oncolytic viruses.
- Optimizing adenovirus engineering to enhance immunogenicity and efficacy is needed.
- The combination of oncolytic adenoviruses and ICIs holds significant therapeutic potential.

5.3K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

5.2K
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...

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

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...
