Summary: Dr Ian MacLennan talks about ways in which the immune system brings about the destruction of foreign cells in the body. This is both a good and a bad thing for the body - good, for instance, if the foreign cells are virus-infected, but bad if the foreign cells are due to, among other things, graft rejection. MacLennan looks in technical detail at some of the reasons for foreign cell rejection, explaining the process by which rejection occurs in depth. 7 segments.
