B-1 B Cells Are Considered a Component of the Innate

Multiple Choice

B-1 B cells are considered a component of the innate rather than the adaptive immune response. The antibodies produced by B-1 B cells generally recognize capsular polysaccharide antigens found on many bacteria and viruses. These antibodies are considered part of the innate immune response because:

A) They recognize pathogens rather than innocuous harmless antigens.
B) They are produced prior to the exposure to the pathogen.
C) They are specific for carbohydrate rather than protein antigens.
D) They are secreted by B-1 B cells starting at 48 hour post-infection.
E) They are not generated by the process of VD-J recombination of immunoglobulin genes.
