Chapter 8 Immuno

Front

What is the initial step for naïve T cells when they encounter an antigen during recirculation through lymphoid organs?

Back

T cells enter a lymph node across high endothelial venules in the cortex.

Front

What happens when a naïve T cell encounters its specific antigen for the first time?

Back

T-cell activation or T-cell priming.

Front

What happens to T cells that do not encounter their specific antigen?

Back

They leave the lymph node in the efferent lymph.

Front

Where does the immune system take the pathogen after capturing it?

Back

To the secondary lymphoid tissues.

Front

What are the finger-like processes called that mature dendritic cells have?

Back

Dendrites.

Front

What is the role of high endothelial venules in T cell migration?

Back

They facilitate the entry of naïve T cells into lymph nodes.

Front

What is T-cell activation?

Back

The process by which a naïve T cell recognizes its specific antigen and begins to proliferate and differentiate.

Front

What is the significance of secondary lymphoid tissues in the immune response?

Back

They are sites where immune cells interact with antigens and initiate adaptive immune responses.

Front

What is the function of dendritic cells in the immune system?

Back

They capture and present antigens to T cells, initiating the immune response.

Front

How do T cells exit the lymph node after not encountering an antigen?

Back

Through the efferent lymphatic vessels.
