Use the following information to answer the following questions.
An otherwise healthy student in your class is infected with EBV, the virus that causes infectious mononucleosis. The same student had already been infected when she was a child, and she had merely experienced a mild sore throat and swollen lymph nodes in her neck. This time, though infected, she does not get sick.
-The EBV antigen fragments will be presented by the virus-infected cells along with which of the following?
A)complement
B)antibodies
C)class I MHC molecules
D)class II MHC molecules
E)Dendritic cells

Question

Quizplus · Accepted Answer

Class I MHC molecules present antigens to CD8+ T cells, and are used to present intracellular antigens such as those derived from viruses. Since the student is infected with EBV, the virus-infected cells will be expressing viral antigens on their surface along with class I MHC molecules, allowing CD8+ T cells to recognize and eliminate the infected cells. Complement, antibodies, and dendritic cells do not directly present antigens to T cells. Class II MHC molecules present extracellular antigens to CD4+ T cells, which are not the primary cells involved in fighting intracellular viral infections.
