B Lymphocytes And Humoral Immunity Flashcards
1
Q
Why is it called humoral immunity?
A
It involves antibodies and they are soluble in the blood and tissue fluid of the body.
2
Q
What happens after a pathogen enters a B cell by endocytosis?
A
It is presented on the surface and the helper cells bind to it stimulating the cloning of B cells (clonal selection). As each clone produces a specific antibody they are called monoclonal antibodies.
3
Q
What do plasma cells do?
A
They secrete antibodies usually into the blood plasma.
Responsible for primary immune response.
4
Q
What are memory cells responsible for?
A
Secondary immune response. When they encounter an antigen they rapidly dive and develop into plasma and memory cells. They provide long term immunity.
