T cells sniff other cells

Categories: Comparisons

An example of metaphor in public science discourse:

"[A T cell] goes around sniffing other cells, basically touching them and trying to find out whether they have been altered in some way, particularly if they are carrying inside them a virus or any other kind of pathogen, and if it finds this pathogen or a virus in your body, it is going to go and kill that virus or pathogen"

Dr Siddhartha Mukherjee, Columbia University
