Animation: Cytotoxic T-cell Activity against target cells
1. Peptide fragments from an infected virus are complexed with
and displayed
on the surface of the infected cell.
2. A cytotoxic T cell interacts with the virus-infected cells by recognizing both the
and the
3. The cytotoxic T cell releases cytotoxins which induce

2. Antigen-presenting macrophages interact with a
that can
recognize the same antigen.
3. During the interaction, the macrophage releases
which stimulates the T-
