And then the cytotoxic T cell can release powerful proteins that ultimately poke holes in this cell and lies the cell, killing that cell off. And then a macrophage can swim by and pick up the remaining debris from that infected cell. So, mechanism number three, we can also actually have a process known as Aglutination. And what Aglutination is, when we form the antibody antigen complex, many of these complexes can actually aggregate to form an insoluble complex. And this insoluble complex also inactivates our pathogen. And then that entire insoluble complex can be picked up by the macrophage.
