Humoral immunity
Storyboard Text
- 1. Macrophage encounters and eats a pathogen floating in the blood so it wouldn't enter the cells
- I am a Macrophage
- I am a pathogen
- Helper t cell and Macrophage interacting through their antigens
- 2. A helper t cell comes and interacts with the macrophage.
- I am a Helper T cell
- Pathogen floating around in the blood
- 3. This activates the b cell because a pathogen is floating in the blood and has not entered the cells
- Regular Cells
- I am a B cell
- 4. The b cell replaces the Macrophage for now, and interacts with the helper t cell to make a memory b cell and plasma b cell so that it will be easier to fight the pathogen next time around.
- I am a Memory B cell
- I am a Plasma cell
- Plasma cell tags pathogen with Antibody, a protein that can recognise the pathogen
- 5. The plasma b cell tags the pathogen using antibody so it doesn't enter any of the cells
- Infected pathogen
- 6. The Macrophage comes in again and eats the cell that is infected with antibiotics, to get rid of it from the immune system
