Questions and Answers

What is the primary reason cancer cells are often able to evade the immune system?

Cancer cells produce antibodies that suppress immune cell activity.

Cancer cells multiply very rapidly creating an overwhelming amount of cells that immune cells can't keep up with.

Cancer cells are very similar to healthy cells and therefore evade detection by the immune system. (correct)

Cancer cells have a unique cellular structure that is unrecognizable by T cells.

What is the key role of neoantigens in the development of personalized cancer vaccines?

To neutralize chemotherapy drugs in the body.

To prevent the cancer from spreading to other parts of the body.

To act as markers that make cancer cells distinguishable from healthy cells, enabling the immune system to target them. (correct)

To boost a patient’s overall immune response, making them resistant to infections.

What is the specific process Dr. Wu's team uses to create personalized cancer vaccines?

Isolating and producing a patient's specific neoantigens in a lab to activate the immune system. (correct)

Using radiation therapy to create new neoantigens on cancer cells.

Genetically engineering T cells to recognize all types of cancer cells.

Administering a general vaccine that targets many different types of cancer cells.

Study Notes

Catherine Wu and the Development of a Cancer Vaccine

Catherine Wu received the 2024 Sjöberg Prize for groundbreaking cancer vaccine research.
She has led a research team at the Dana-Farber Cancer Institute in Boston since 2000.
Her research focuses on personalized cancer vaccines, targeting unique DNA mutations in individual tumors.
These mutations create neoantigens, proteins slightly different from healthy cells, recognizable by the immune system's T cells.

How Personalized Cancer Vaccines Work

The immune system typically struggles to identify and attack cancer cells due to their similarities to healthy cells.
Wu's team identified and characterized these neoantigens, enabling personalized cancer vaccines.
The vaccines are created by isolating and producing a patient's specific neoantigens in a lab.
Injected neoantigens activate the immune system to target and destroy cancer cells.

Potential Impact on Cancer Treatment

Wu's research shows promise in treating various cancers, including melanoma.
This research offers hope for effective treatments for previously difficult-to-cure cancers.
The Sjöberg Prize, awarded by the Royal Swedish Academy of Sciences and funded by the Sjöberg Foundation, acknowledges Wu's contribution to cancer research.
