Jemima was infected with SARS-CoV-2 virus.  She started feeling very sick, but fortunately her adaptive immune response was activated to fight the virus.

Part C

Before the adaptive response became activated, natural killer cells interacted with epithelial cells in Jemima’s lungs.  Describe the molecular interactions that occurred between the NK cells and both infected and uninfected epithelial cells. 

On a clean sheet of paper, draw shapes like those below, and show the molecular interactions that happened between the cells on the drawing. Photograph your drawing and upload* here to receive feedback.
