B LYMPHOCYTES AND HUMORAL IMMUNITY Flashcards
How does the antigen enter the B cell
endocytosis
What happens after endocytosis
it gets presented on the surfaced (processed), and T-cells bind to the processes antigens & stimulates the B-cell to divide by mitsos
What does the division of B-cells produce
plasma cells
What do plasma cells produce
a group of antibodies all complementary to a specific foreign antigen
Give an example of a pathogen that also causes toxins
cholera
What does each toxin molecule also act as
an antigen
What are monoclonal antibodies produced by
the clones of B cells (plasma cells)
What are monoclonal antibodies
antibodies that target the same antigens
What do the cells produced in the clone of B cells become (2 points)
1) plasma cells
2) memory cells
What do plasma cells do
secrete antibodies usually into blood plasma
How long do plasma cells survive for
for a few days
Are B cells present since and what happens when a pathogen is present
birth, they multiply
How many antibodies can each plasma cell make every second
2000
What do the antibodies secreted by plasma cells do
destroy the antigen
What is the production of antibodies and memory cells known as
primary immune response
