The Antigen-Binding Receptor Expressing Hepatitis Antigen in an Infected Liver

Question

The antigen-binding receptor expressing hepatitis antigen in an infected liver cell would be
A) TCR.
B) MHC II.
C) MHC I.
D) CD4.
E) CD8.

Accepted Answer

MHC I is responsible for presenting intracellular antigens, such as hepatitis antigens in infected liver cells, to CD8+ T cells. Therefore, the antigen-binding receptor in this scenario would be the CD8 molecule, which is a co-receptor that binds to the MHC I complex.
