10 Questions
What is the main function of T cells in the adaptive immune system?
T cells play a central role in the adaptive immune system.
Where do T cells mature, differentiate, and develop their specific functions?
T cells mature, differentiate, and develop their specific functions in the thymus gland.
Describe the process of T cell activation.
T cell activation involves antigen recognition by a TCR with CD4 or CD8 proteins, followed by co-stimulation.
What are the two signals required for T cell activation?
The first signal is antigen recognition by a TCR with CD4 or CD8 proteins, and the second signal is co-stimulation.
How do B cells transform into antibody-secreting plasma cells?
B cells transform into antibody-secreting plasma cells by binding to activated helper T cells.
What is the difference between active and passive immunity?
Active immunity involves the production of antibodies, while passive immunity involves the transfer of pre-formed antibodies.
How are antibodies acquired in passive immunity?
Antibodies in passive immunity are acquired through transfer from another source, either naturally (such as from the mother) or artificially (such as through immune serum).
What is the role of Class II MHC proteins in the immune response?
Class II MHC proteins help B cells present antigen fragments to activated helper T cells.
Why are T cells named after the thymus gland?
T cells are named after the thymus gland because it is where they mature, differentiate, and acquire their specific functions.
What is the significance of the B cell receptor in the immune response?
The B cell receptor is used by B cells to bind to their matching antigens.
