Choose the incorrect:
Characteristics of both T and B cell (TCR and BCR) antigen receptors:
A.
B.
C.
D.
E.
Both have a non-covalently associated signaling subunit.
Both have a transmembrane domain.
Both consist of heavy and light chains.
They recognize epitopes.
Generation of several millions of different variable domains is possible.
These receptors are able to bind to pathogens directly:
A.
B.
C.
D.
E.
most cell surface toll like receptors (TLR)
B cell receptors (BCRs)
mannose receptors
T cell receptors (TCRs)
scavenger receptors
Characteristics of the antigen presentation by B cells:
A.
B.
C.
D.
E.
When antigens of intracellular pathogens are presented T lymphocytes increase the activity of the
presenting B cells.
DNA recognized by B cells is not presented to T cells.
Both MHC I- and MHC II-associated peptides can be presented.
Various peptides can be presented simultaneously in complex with the MHC.
Antigen presentation to T helper cells occurs primarily in the secondary lymphoid organs/tissues.
