Cancer Vaccines

1.3K
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...

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.

Rous Sarcoma Virus (RSV) and Cancer

6.6K
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.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Vaccines

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the...

Area of Science:

  • Vaccinology
  • Molecular Biology
  • Immunology

Background:

  • Messenger RNA (mRNA) vaccines represent a significant advancement over traditional vaccines.
  • They offer advantages in rapid development, immunogenicity, and antigen design flexibility.

Purpose of the Study:

  • To systematically review the research progress of mRNA vaccines.
  • To cover structural composition, novel subtypes, immune activation mechanisms, and delivery systems.
  • To detail clinical applications in infectious diseases and cancer therapy, and discuss limitations and future directions.

Main Methods:

  • Systematic review of core research progress in mRNA vaccine technology.
  • Analysis of structural elements, subtypes, immune mechanisms, and delivery systems.
  • Examination of clinical application status and future prospects.

Main Results:

  • mRNA vaccines utilize five functional elements and novel subtypes (linear, self-amplifying, circular RNA).
  • Immune activation mimics viral infection, engaging innate and adaptive immunity.
  • Various delivery systems (LNP, DC, protamine, exosomes, polymers) show distinct performances.
  • Promising preclinical and clinical results exist for infectious diseases (influenza, SARS-CoV-2, HIV) and cancer therapy.
  • Limitations include delivery inefficiency, production costs, and cold chain requirements.
