Insights

Oncolytic viruses (OVs) are engineered to target cancer cells, offering a promising cancer therapy. Genetic modifications enhance their safety and effectiveness, paving the way for innovative treatments.

Area of Science:

  • Oncology
  • Virology
  • Immunotherapy

Background:

  • Oncolytic viruses (OVs) selectively destroy cancer cells with minimal harm to healthy tissues.
  • Historical observations noted tumor regression during systemic viral infections.
  • Modern technology allows for harnessing OVs as anti-cancer therapeutics.

Purpose of the Study:

  • To review strategies for enhancing OV therapeutic potential.
  • To explore the synergistic effects of combining OVs with other cancer treatments.
  • To elucidate the oncolytic mechanism of OVs.

Main Methods:

  • Genetic modification of OVs to reduce virulence, increase specificity, and boost immunogenicity.
  • Review of current research on OV therapeutic strategies.
  • Analysis of clinical trial outcomes for selected OVs.

Main Results:

  • OVs demonstrate selective cancer cell elimination.
  • Genetic engineering improves OV safety and efficacy.
  • Combination therapies with OVs show synergistic benefits.

Conclusions:

  • Oncolytic virus therapy is a promising approach for cancer treatment.
  • Advancements in OV technology, including Plant virus-based Nanoparticles (PVNPs) and Zika virus applications, offer new therapeutic avenues.
  • Further research and clinical trials are essential to fully realize the potential of OV immunotherapy.

Cancer Vaccines

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

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...

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.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
