Lesson Flashcards: Specific Immune Response: Antibodies Biology

Clonal selection

The process by which T cells and B cells with receptors that bond with specific antigens are selected to multiply and proliferate

Clonal expansion

The production of daughter cells all arising from a single parent cell that occurs during a humoral immune response

Antibody (immunoglobulin, Ig)

A globular protein produced by B lymphocytes that is adapted to bind with a specific antigen

Antigen-presenting cell (APC)

A type of immune cell that helps to trigger an immune response by presenting antigens bound to its surface to other immune cells

Antigens

Substances that can trigger an immune response

B lymphocytes

Lymphocytes that mature in bone marrow and secrete antibodies

B cell receptor (BCR)

An antibody attached to the cell membrane of a B lymphocyte that stimulates B cell activation when it binds with a complementary antigen

Plasma cell

A type of immune cell that makes large amounts of a specific antibody
