Question 1 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 2 of 5
Multiple sclerosis
Correct Answer: B
Rationale: Multiple sclerosis is associated with HLA-DR2.
Question 3 of 5
generated in vesicles (extracellular infection, e.g. bacteria) bind to MHC molecules for presentation to T cells.

Immunoreceptor tyrosine-based activation motifs (ITAMs) are essential for signal transduction in cells.
Correct Answer: D
Rationale: ITAMs are critical for signal transduction in both B cells (via BCR) and T cells (via TCR).
