Then, if you ever encounter the real pathogen, your body can fight it off. In this medical biotechnology science project, you will make a model of the immune system in the human body and investigate how memory cells help the body fight off an infection.f a pathogen has memory cells that remember it, then the immune system should be making more antibodies to fight off the pathogen. As a result, you will use your model to test how having more antibodies helps the immune system fight off pathogens. 1  In your lab notebook, create a data table like Table 1 below.
