Memory B cells provide the quick anamnestic antibody response that follows after antigen reexposure. ... Plasma cells are terminally differentiated cells of the B lymphocyte lineage, the cells uniquely able to secrete antibody and thus the cell responsible for antibody-mediated immunity.

Are B cells and plasma cells the same thing?
Plasma cell, short-lived antibody-producing cell derived from a type of leukocyte (white blood cell) called a B cell. ... B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell.
Are plasma cells B cells?
Plasma cells, also called plasma B cells, are white blood cells that originate in the bone marrow and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens.
What are the functions of plasma cells and memory B cells?
Humoral immunity appears to be based on immunological memory provided by memory plasma cells, which secrete protective antibodies, and memory B cells, which react to antigen challenge by differentiating into plasma cells.
What do B cells do in the body?
B cells are at the centre of the adaptive humoral immune system and are responsible for mediating the production of antigen-specific immunoglobulin (Ig) directed against invasive pathogens (typically known as antibodies).
What happens if you have no B cells?
Without B-cells, your body would not be as effective at fighting off a number of common bacteria and viruses; and you would lack the long-lasting "memory antibody" function that is typical after recovering from an infection or after being immunized against a specific infectious invader.
Are B cells white blood cells?
B cells are a type of lymphocyte that are responsible for the humoral immunity component of the adaptive immune system. These white blood cells produce antibodies, which play a key part in immunity. Each B cell contains a single round nucleus.
Do plasma cells circulate in the blood?
Plasma cells are not normally found in the circulation, but rather remain residents in their organ of choice for life; any antibody-secreting cells in the blood en route to, for example the bone marrow, are plasmablasts. ... Plasma cells are easily distinguished from mature B cells by their morphological appearance.
Do plasma cells divide?
The plasma cells are terminally differentiated, meaning they do not divide and are short-lived. The impressive thing about plasma cells is not their lifespan, but their function. Plasma cells secrete antibodies at an incredible rate: thousands of molecules per second.
Why are plasma cells important?
Plasma cells (PCs) represent the terminal differentiation step of mature B lymphocytes. These cells are most recognizable for their extended lifespan as well as their ability to secrete large amounts of antibodies (Abs) thus positioning this cell type as a key component of humoral immunity.
What is the main function of plasma cells?
Plasma cells are differentiated B-lymphocyte white blood cells capable of secreting immunoglobulin, or antibody. These cells play a significant role in the adaptive immune response, namely, being the main cells responsible for humoral immunity.
What is the function of plasma cells in the immune system?
Plasma cells are terminally differentiated B cells that secrete antibodies, important for immune protection, but also contribute to any allergic and autoimmune disease.
What is the role of plasma cells in the blood?
Plasma cells develop from B lymphocytes (B cells), a type of white blood cell that is made in the bone marrow. Normally, when bacteria or viruses enter the body, some of the B cells will change into plasma cells. The plasma cells make antibodies to fight bacteria and viruses, to stop infection and disease.
