12 Questions
What type of antigens can membrane-bound antibodies of B lymphocytes recognize?
Many types of chemical structures
What do the antigen receptors of B and T lymphocytes have in common?
Transmit biochemical signals that are fundamentally the same
What is unique about the function of T cell antigen receptors (TCRs) compared to antibodies (immunoglobulins)?
TCRs only function as membrane receptors
How do most T cell antigen receptors recognize antigens?
Only peptides bound to major histocompatibility complex (MHC) molecules
What is essential for signaling in lymphocytes, despite single antigens being shown in recognition?
Binding of two or more receptors to adjacent antigen molecules
What is a critical characteristic of membrane-bound antibodies serving as B lymphocyte antigen receptors?
Ability to recognize many types of chemical structures
What is the principal function of cellular receptors in the immune system?
Triggering responses of the cells
Why do antigen receptors of lymphocytes need to be able to bind to and distinguish between many different chemical structures?
To recognize a large variety of different antigens
Which type of receptors do B lymphocytes express to recognize antigens?
Membrane-bound antibodies
Why are antigen receptors considered clonally distributed in lymphocytes?
To ensure each clone is specific for a distinct antigen
What makes up the immune repertoire?
The total number of distinct lymphocyte clones
In adaptive immunity, what do effector T cells and antibodies recognize to perform their functions?
Antigens
