Term
Antigens
Definition

Antibody generating

Molecule that induces an immune response

Term
Epitopes
Definition
Specific regions of an antigen to which antibodies bind
Term
Antibodies are produced by
Definition
B-lymphocytes
Term
Antibodies
Definition
Bind to specific antigens
Term
Epitopes
Definition
Specific regions of an antigen to which antibodies bind
Term
Agglutination
Definition

 

Response to antibody

Clumps the antigen and things bound to it

Term
Precipitation
Definition

Response to antibody

Binding to antigen makes it insoluble in solution

Term
Neutralization
Definition
Binding of antigen to AB inhibits antigen function
Term
Opsonization
Definition
Binding of AB to antigen to encourage phagocytosis by macrophages
Term
Complement response
Definition
Binding of antigen to antibody promotes the insertion of a pore
Term
Clonal selection
Definition

Preexisiting population of specific B cells only bind to specific antigens

When binding occurs, the specific B cell proliferates to produce more antibodies

Term
How are antibodies encoded? From where does AB diversity arise?
Definition
  • Shuffling of different domains that are encoded by genes
  • Deletion of part of the constant region can create a new Ig, too
