Snemalna Knjiga Besedilo

  • Macrophage encounters, eats a pathogen floating in the blood.
  • Oh no! I am being eaten!
  • NOSE
  • I am a macrophage. I am eating this pathogen.
  • PATHOGENS ENTER THROUGHTHE NOSE AND ENTER THE BLOOD STREAM
  • The macrophage displays an antigen (a molecule on the outside of pathogens that signals the body to generate immune response) specific to the pathogen it ate to helper T cells. The helper T cell activates the other parts of the acquired immune system.
  • I will display the pathogen's antigens to helper T cells, who will activate other types of white blood cells.
  • I am an antigen.
  • I am a helper T cell. I interact with the antigen and activate memory T and killer T cells specific to this pathogen.
  • I am a memory T cell I remember a specific pathogen.
  • I connect with T cells, activating and differentiating them into Killer T cells and Memory T cells.
  • T cells interact with Helper T cells, which activates and differentiates the T cells into Killer T cells and Memory T cells.
  • I am a T cell. I interact with the helper T cell to be activated and differentiated into two types of cells.
  • I am a killer T cell. I attack and destroy cells infected with a specific pathogen.
  • I am shooting perforin at the infected cell.
  • Killer T cells attack infected cells with perforin, a protein that binds to their cell membranes.
  • I watch this happening from the side.
  • I made the infected cell burst, which destroyed it.
  • This causes the cell membrane to burst, and destroys the infected cell before it has a chance to help the pathogen reproduce.
  • I watch this happening from the side.
  • Memory T cells remember the pathogen, which results in a faster Killer T cell response in future infections, which would result in infected cells being more quickly destroyed, leading to less chances for the pathogen to reproduce.
  • We saw the Killer T cells destroy the infected cells, which stopped the pathogen from further reproducing.
  • We will make sure our body remembers these pathogens. If they come back, we will be prepared and they will be destroyed even faster.
