Cell mediated immunity
Storyboard Text
- 1. Macrophage encounters and eats a pathogen floating in the blood.
- I am a Macrophage
- I am a Pathogen
- Macrophage and Helper t cell communicating through their antigens
- 2. A helper t cell comes and interacts with the macrophage in order to activate the killer t cell this time.
- I am a Killer t cell
- I am Helper t cell
- Pathogen spliting into multiple parts once infecting the cell
- Regular Blood cells
- 3. The helper t and Macrophage activates the killer t cell because a pathogen has gotten into the cell.
- 4. The killer t cell interacts with the helper t cell to make a memory b cell and another killer t cell to remember the antigen of the killer t cell.
- I am Memory b cell
- 5. The killer t cell that was just made will connect to the infected cell’s antigen using it’s antigens so that it could destory the infected cell
- Killer t cell and infected cell connecting with both of their antigens
- 6. Once connected with the infected cell’s antigen, the killer t cell will be able to destroy the infected cell by shooting it with perforin, a protein that can kill bacteria
- Killer t cell shooting perforin, a protein like substance similar to antibody
