10 Questions
Which type of cells are CD3+ and CD4+?
T helper cells
What is the difference between generative lymphoid organs and peripheral (secondary) lymphoid organs?
Generative organs activate immune responses, while peripheral organs host mature lymphocytes
What is the difference between a naïve lymphocyte and an effector lymphocyte?
Naïve lymphocytes recognize antigens but do not perform the functions required to eliminate antigens, while effector lymphocytes have the ability to eliminate antigens
What is the key distinction between naive lymphocytes and effector lymphocytes in the B lymphocyte lineage?
Naive lymphocytes primarily act as receptors for antigens, while effector lymphocytes actively produce molecules such as antibodies.
Where do memory cells come from?
Memory cells are generated from the progeny of antigen-stimulated lymphocytes or B lymphocytes.
What is the main function of effector lymphocytes in the B lymphocyte lineage?
To actively produce molecules such as antibodies to contribute to the elimination of antigens.
What represents the characteristic migration of naive lymphocytes in the B lymphocyte lineage?
Peripheral lymphoid tissues upon encountering antigens.
What is the frequency of cells responsive to a particular antigen for effector lymphocytes?
High frequency
Which immunoglobulin (Ig) isotype is primarily associated with naive lymphocytes in the B lymphocyte lineage?
IgM, IgD
What happens to the level of plasma cells during an immune response?
Increase during immune response
