AQA A Level Biology復習筆記2.5.5 The Role of Antigen-Presenting Cells
The Role of Antigen-Presenting Cells
- T-lymphocytes produce an immune response when they are exposed to a specific antigen
- T cells will only bind to an antigen if it is present on the surface of an?antigen-presenting cell
- These cells present the antigens from toxins, foreign cells and ingested pathogens
- They help to recruit other cells of the immune system to produce a specific immune response
- An?antigen-presenting?cell is one of the host's cells
- It might be a?macrophage?or a body cell that has been invaded by a pathogen and is?displaying the antigen on its cell surface membrane
- Once the surface receptor of the T cell binds to the specific complementary antigen it becomes sensitised and starts dividing to produce a clone of cells
