Antigen-presenting cells infected by a virus can present processed viral antigen on their surface to T cells through these.

Question

Quizplus · Accepted Answer

Antigen-presenting cells infected by a virus will present viral antigen on their surface through MHC I molecules to CD8+ T cells, which will then be activated to attack and eliminate the virus-infected cells. MHC II molecules are typically used to present antigen from extracellular sources to CD4+ T cells, but are not involved in presenting antigens from intracellular sources, such as viruses. Interleukin 2, tumor necrosis factor alpha, and interferon gamma are all cytokines that are produced by T cells and other cells of the immune system, but are not directly involved in the presentation of viral antigen.
