Cancer Vaccines

1.0K
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...

Viral Mutations00:36

Viral Mutations

39.9K
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...

Second Law of Thermodynamics

26.9K
In the quest to identify a property that may reliably predict the spontaneity of a process, a promising candidate has been identified: entropy. Processes that involve an increase in entropy of the system (ΔS > 0) are very often spontaneous; however, examples to the contrary are plentiful. By expanding consideration of entropy changes to include the surroundings, a significant conclusion regarding the relation between this property and spontaneity may be reached. In thermodynamic models, the...

Gibbs Free Energy

One of the challenges of using the second law of thermodynamics to determine if a process is spontaneous is that it requires measurements of the entropy change for the system and the entropy change for the surroundings. An alternative approach involving a new thermodynamic property defined in terms of system properties only was introduced in the late nineteenth century by American mathematician Josiah Willard Gibbs. This new property is called the Gibbs free energy (G) (or simply the free...

Area of Science:

  • Biotechnology
  • Immunology
  • Virology

Background:

  • Many deadly viruses lack approved vaccines, necessitating novel therapeutic strategies.
  • Existing vaccines, like for Hepatitis B virus (HBV), are highly effective.
  • Viral Universal Vaccines (VUVs) are engineered to redirect existing immunity against different viral infections.

Purpose of the Study:

  • To biomolecularly engineer an HIV universal vaccine (HIVUV).
  • The HIVUV incorporates CD4 or anti-gp120 for HIV targeting and HBsAg for immune response.
  • The aim is to redirect, accelerate, and amplify HBV-induced immunity against HIV.

Main Methods:

  • Biomolecular engineering of HIVUV with CD4/anti-gp120 and HBsAg domains.
  • Immunoblotting and magnetic activated molecular sorting to confirm specificity.
  • Flow cytometry and nuclear magnetic resonance to assess efficacy in engaging immune response.

Main Results:

  • Engineered HIVUV demonstrated high specificity for binding HIV.
  • The vaccine effectively engaged the immune system of HBV-immunized patients against HIV.
  • Administration of HIVUV led to undetectable HIV viremia and protected CD4+ cells.

Conclusions:

  • Proof of concept for the high efficacy of VUV, specifically HIVUV, in eliminating HIV.
  • The developed methods are adaptable for creating VUVs against other deadly viral infections.
  • Further development is underway to apply this technology to a broader range of viral diseases.
