Question 1 of 5
In comparison toαβ T cells, δγ T cells and are hypothesized to be a line of immune defense.
Correct Answer: B
Rationale: δγ T cells do not typically use MHC for antigen recognition and are considered a primary line of defense.
Question 2 of 5
Genes involved in antigen processing
Correct Answer: D
Rationale: LMP and TAP genes are involved in antigen processing for MHC class I presentation.
Question 3 of 5
Because of a lack of genetic recombination in the MHC, blocks of alleles (haplotypes) are inherited together, and they are identical in families. Which of the following is the likely result of this?
Correct Answer: A
Rationale: Identical HLA haplotypes in families simplify tissue transplantation due to matched alleles.
Question 4 of 5
Multiple sclerosis
Correct Answer: B
Rationale: Multiple sclerosis is associated with HLA-DR2.
Question 5 of 5
generated in vesicles (extracellular infection, e.g. bacteria) bind to MHC molecules for presentation to T cells.
Correct Answer: B
Rationale: Extracellular antigens (e.g., bacteria) are processed in vesicles and presented by MHC Class II to CD4+ T cells, while intracellular antigens are presented by MHC Class I to CD8+ T cells.
