Chapter 9, Problem 9TY
Summary Introduction
Introduction:
In the war against pathogens, the body has many cells in its arsenal, each of which performs a different role. The immune system either produces antibodies to mark the pathogen for destruction or deploys armies of cytotoxic T cells (TC), which can directly phagocytose the antigen. As each antigen is different, the mechanism employed for their elimination is varied too.
