Question 2

What tends to be poor antigens because of their wide distribution, relative simplicity, structure instability, and rapid metabolism?

Answer 2

Lipids

Question 3

Answer 3

Good

Question 4

What MHC molecules can present lipid, lipoprotein, and glycolipid antigens to lymphocytes?

Answer 4

CD1

Question 5

What are very poor antigens because they are relatively simple, flexible, and are very rapidly degraded?

Answer 5

Mammalian nucleic acids

Question 13

What is both antigenic and immunogenic?

Answer 13
