Questions and Answers

What is the primary mechanism by which Catherine Wu's personalized cancer vaccines work?

  • Introducing healthy DNA into tumor cells to correct mutations.
  • Blocking the blood supply to tumors, causing them to starve and shrink.
  • Directly attacking tumor cells with synthetic antibodies.
  • Enhancing the immune system's ability to recognize and target tumor neoantigens. (correct)

Why are tumor neoantigens crucial for the effectiveness of personalized cancer vaccines?

  • They are present in all healthy cells, ensuring broad immune activation.
  • They suppress the immune system, preventing autoimmune reactions.
  • They are unique to tumor cells, allowing the immune system to specifically target cancer without harming healthy tissue. (correct)
  • They are universally identical across all types of cancer.

What distinguishes Catherine Wu's approach to cancer treatment from traditional methods like chemotherapy and radiation?

  • It focuses on broadly suppressing the immune system to reduce inflammation.
  • It relies on synthetic chemicals to directly kill cancer cells.
  • It is a personalized treatment that utilizes the patient's own tumor mutations to create a targeted vaccine. (correct)
  • It involves the direct surgical removal of tumors.

Study Notes

  • Catherine Wu has made significant progress in cancer research, specifically in the development of a cancer vaccine.
  • Wu's work enables the creation of personalized vaccines for cancer patients.
  • This progress offers a potential treatment option for various cancers, including currently incurable types.

Melanoma

  • Melanoma, a type of skin cancer, is a common and threatening cancer.
  • Current treatments for melanoma have improved, but new strategies are needed.
  • Some patients do not respond well to current melanoma treatments, creating a need for new treatments.
  • Catherine Wu's research focuses on improving outcomes for melanoma patients and those with other cancers lacking effective treatments.

Tumors and Mutations

  • Tumors consist of cells that divide and grow uncontrollably.
  • Tumor cells accumulate mutations (DNA faults) over time.
  • The immune system often struggles to recognize cancer cells, but can attack with assistance.

Catherine Wu's Research

  • Catherine Wu is an oncologist and haematologist.
  • Since 2000, she has led a research team at the Dana-Farber Cancer Institute in Boston.
  • Wu's research focuses in new methods to assist the immune system in recognizing tumors, leading her into a new field.
  • Wu aimed to develop a therapy that strengthens the immune system through personalized vaccines.
  • The personalized vaccine are based on small DNA mutations in the patient’s tumor cells.
  • As tumors grow, genetic mutations often occur in their cells.
  • These mutations cause slight differences in proteins within tumor cells compared to healthy cells.

Tumour Neoantigens

  • These differing proteins generate tumour neoantigens, enabling recognition by the immune system’s T cells.
  • Wu has successfully characterized these neoantigens as well as identified which are on the cell's surface, enabling patient-specific cancer vaccines.
  • Wu's work has enables the development of tumour-specific cancer vaccines.
  • Wu developed a prototype for a tumour-specific cancer vaccine.
  • The vaccine is made from a number of the patient’s tumour neoantigens, produced in a laboratory.
  • The neoantigens are injected into the patient to activate the immune system.
  • The activated immune system discovers, attacks, and sometimes destroys cancer cells.
  • This treatment is exceptional because it utilizes the unique characteristics of a patient's tumor cells to produce a tumour-specific vaccine.
  • This treatment exemplifies a personalized treatment strategy.
  • Early stage research is seeing responses in certain forms of cancer considered to be almost incurable.

Impact and Hope

  • Camilla Lindfors received two years of standard treatment for her skin cancer, which resulted in the disappearance of her cancer.
  • Lindfors states this is a vital milestone on the road to developing a cancer vaccine for melanoma.
  • Wu's research gives hope for developing vaccines for numerous cancer types in the future.

Sjöberg Prize

  • Catherine J. Wu is awarded the 2024 Sjöberg Prize.
  • Wu expresses immense gratitude for the prize, recognizing it as a shared vision with her research group.
  • Wu is hopeful that the impact of her work will be seen across broad populations and become part of standard cancer treatment offerings.
  • The Sjöberg Prize is awarded by the Royal Swedish Academy of Sciences and financed by the Sjöberg Foundation.
