HMX IMMUNOLOGY FINAL 2026
STUDY GUIDE PRACTICE
QUESTIONS DETAILED SOLUTIONS
◉ Which of the statements below correctly describes innate immune
cells? Answer: Innate immune cells recognize conserved pathogen-
associated molecular patterns
◉ Some of the steps of an acute inflammatory response are listed below.
Which of these steps would occur first in a given episode of
inflammation? Answer: microbial molecules bind to innate immune
receptors
◉ Which of these factors does NOT contribute to antibody diversity?
Answer: millions of different inherited antibody genes
◉ Which of the statements below best describes the differences in
antigen recognition by B cells and T cells? Answer: B cells can
recognize extracellular antigens of any kind while T cells can only
recognize complexes of peptides bound to cell surface display molecules
◉ What is the source of peptides presented on MHC class I molecules
and MHC class II molecules? Answer: Peptides from proteins broken
down in lysosomes are presented on MHC class II molecules. Peptides
from proteins broken down in proteasomes are presented on MHC class
I molecules
