IMMUNE RESPONSE

Specific

Immunotherapy treatment activates T cells and B cells that target specific tumor antigens3-5

  • The activated immune system is primed to recognize tumor antigens expressed by each patient’s unique and frequently changing population of cancer cells3
  • Some activated T cells kill tumor cells directly or indirectly3
  • Some activated T cells activate B cells, which become antibody-producing plasma cells3

Adaptable

Immunotherapy treatment is designed to support the immune system’s ability to adapt its attack over time3,5-8

  • Each patient’s population of tumor cells mutates over time, which may result in resistance to traditional anticancer therapies3
  • When a tumor cell is killed, additional antigens are released, stimulating activation of new populations of T cells and B cells that recognize tumor antigens3,4,6,7
  • This can result in an expanding cascade of immune cells able to recognize cancer cells bearing a variety of tumor antigens as the tumor mutates over time5-8

Durable

Immunotherapy treatment stimulates immunologic memory, which
may lead to a prolonged antitumor response3,9-10

  • Some activated immune cells become memory cells, which remain primed to stimulate an immune response when tumor cells bearing target antigens are encountered within the body3,9-10

A natural immune response involves 3 different types of cells1:

Antigen Presenting Cells(APCs) identify and uptake foreign antigens to present them to T cells

antigen-presenting-cells

T cells are activated by APCs to recognize and destroy cells containing foreign antigens

t-cells

B cells produce antibodies specific to foreign antigens

b-cells
