Specific Immune Response: B-Lymphocytes Flashcards
1
Q
What are the steps of immune response?
A
1) phagocytosis
2) t-cells activated
3) b-cells activated
2
Q
What are b-cells activated by?
A
interleukins released by activated t-helper cells
3
Q
What does each b-cell have?
A
its own antibody on its surface
4
Q
What do b-cells with a complimentary antibody to the pathogen’s antigen form?
A
an antigen-antibody complex
5
Q
What kind of cloning do b-cells go through?
A
clonal selection and clonal expansion
only the B-cells that form an antigen-antibody complex will divide to make many clones of itself called plasma cells + memory cells
6
Q
What are plasma cells?
A
clones of the clonally selected b-cell
they make many copies of antibodies and secrete them into the blood stream
7
Q
What are memory cells?
A
plasma cell that is kept after infection is over
