20 Questions
What is the key functional distinction between naive B lymphocytes and effector B lymphocytes?
Naive lymphocytes are primarily receptors for antigens, while effector lymphocytes actively produce molecules such as antibodies.
What is the characteristic migration of activated lymphocytes?
Peripheral lymphoid inflamed tissues upon encountering antigens.
What is the membrane immunoglobulin (Ig) isotype characteristic of naive B lymphocytes?
IgM, IgD
What cells produce memory cells?
Memory cells are produced from the progeny of antigen-stimulated lymphocytes or B lymphocytes.
Which cells are CD3+ and CD4+?
Regulatory T cells and Helper T lymphocytes
Where do naive lymphocytes mature?
Bone marrow
What is the main function of peripheral (secondary) lymphoid organs?
Activating immune responses
What is the difference between generative lymphoid organs and peripheral (secondary) lymphoid organs?
Location of lymphocyte maturation
What happens when naive lymphocytes recognize microbial antigens?
They undergo proliferation and differentiation into memory cells
Which cells are the differentiated progeny of naive cells?
Effector cells
What is the key distinction between naive B lymphocytes and effector B lymphocytes?
Naive lymphocytes primarily act as receptors for antigens, while effector lymphocytes actively produce molecules like antibodies.
Where do effector B lymphocytes migrate to during an immune response?
Peripheral tissues and organs encountering antigens
What is the membrane immunoglobulin (Ig) isotype characteristic of effector B lymphocytes?
IgG, IgA, and IgE
What cells are the differentiated progeny of antigen-stimulated B lymphocytes?
Memory B cells
