Cellular immune response 2 Flashcards
1
Q
What is the main difference between TCR binding between a conventional antigen vs. a super antigen?
A
conventional antigen fills the binding groove while super antigen binds only to the beta chain
2
Q
Do super antigens require MHC antigen presentation?
A
no
3
Q
What are some examples of outcomes of super antigen binding to a TCR?
A
powerful T cell response
high cytokine production
toxic shock syndrome
4
Q
What type of immune response do Th1 cells promote?
A
cellular immune response
5
Q
What type of immune response do Th2 cells promote?
A
humeral immune response
6
Q
What occurs after a naive T cell interacts with a dendritic cell?
A
asymmetrical division: side touching the dendritic cell becomes a helper T cell, other side becomes a memory T cell
