6 Questions
What is the role of MHC class I proteins in the immune response to viruses?
They display pieces of protein from inside the infected cell on the cell surface
What is the function of cytotoxic T cells in the immune response to viruses?
They kill cells that are infected with viruses
How do cytotoxic T cells recognize virally-infected cells?
They have specialized proteins on their surface
What happens when a cell is infected with a virus in terms of MHC class I proteins?
Pieces of peptide, including viral protein fragments, are displayed on the cell surface
What is the primary role of T cells in the immune response to viruses?
To recognize and eliminate virally-infected cells
Match the following components of the immune system with their functions:
Cytotoxic T cell = Kills cells infected with viruses MHC class I proteins = Display pieces of protein from inside the cell T cell = Circulates looking for infections Toxic mediators = Used by cytotoxic T cells to kill infected cells
Test your knowledge of the immune system's response to viral infections with this quiz. Explore how cytotoxic cells work to fight off viruses by displaying infected cells to the immune system. Gain insight into the role of class I major histocompatibility complex molecules in this process.
