Answer
Presentation of viral antigens on the macrophage surface
Solution
a
Antigen processing: After a virus is degraded within a macrophage, viral proteins are processed into peptides
b
Antigen presentation: These peptides are then presented on the macrophage surface bound to major histocompatibility complex (MHC) molecules
c
Activation of T cells: The presented antigens are recognized by T cells, leading to their activation and initiation of an adaptive immune response
Key Concept
Antigen presentation by MHC molecules
Explanation
After degradation of a virus, the macrophage presents viral antigens on its surface to activate T cells and initiate an adaptive immune response.
