Microorganisms in Medicine and Therapeutics

868
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.

Gene Therapy00:59

Gene Therapy

27.2K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Cancer Vaccines01:30

Cancer Vaccines

882
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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

1.7K
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.

Combination Therapies and Personalized Medicine

5.8K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Area of Science:

  • Immunology
  • Vaccinology
  • Gene Therapy

Background:

  • Therapeutic vaccines are needed to restore immune function in conditions like cancer and persistent viral infections.
  • Effective immunization relies on dendritic cells (DCs) presenting antigens to T lymphocytes.
  • Existing vaccine design faces challenges due to the complexity of reprogramming downregulated immune systems.

Purpose of the Study:

  • To propose a novel immunization protocol for designing more effective therapeutic vaccines.
  • To leverage advancements in dendritic cell biology and viral vector technology for improved vaccine strategies.

Main Methods:

  • Engineering viral vectors to express antigens.
  • Targeting antigen expression to activated dendritic cells (DCs).

Main Results:

  • The proposed method aims to enhance the priming of immune responses.
  • This approach is expected to overcome challenges in reprogramming suppressed immune systems.

Conclusions:

  • Engineering viral vectors for antigen expression in activated DCs represents a rational and potentially highly effective vaccine design.
  • This strategy holds promise for developing next-generation therapeutic vaccines against challenging diseases.
