Chapter 27, Problem 7SA
Summary Introduction
To analyze:
How it is possible to receive transplanted organs from another person, when the body attacks non-self cells.
Introduction:
Regardless of whether a foreign cell is a pathogen, or from another multicellular organism, the body will attack it if it recognizes it as foreign.

If the main criteria for an antigen is that it is foreign, I'm curious how the body responds in the case of tissue/organ transplant. I've heard of cases where the body rejects the new organ. Is this why? What makes some bodies of recipients reject the donor organs while others will accept?
An antigen acts is a molecule that acts like a name tag, allowing
the immune system to recognize the cell it is attached to. The
name tag might say: "Hello I'm... a deadly virus," or “Hello
I'm... a healthy human cell." It is very important that an
antigen for a deadly virus and a healthy human cell are very
different, so that the immune system does not make a mistake
and attack healthy human body cells.
Which of the following molecules do you think would make
good antigens for recognizing a pathogen? Justify your
answer.
You may choose more than one.
1) a cell wall protein
2) a piece of DNA inside a cell
3) a protein that is part of a flagella
4) a uniquely shaped protein that is part of a virus
5) a protein that is only made by prokaryotic cells
6) a protein that is only made by eukaryotic cells
Which cells are involved in transplant rejection?
