CELL CULTIVATIONS QUIZ

IgG

IgD

IgM

IgA

added to dimeric IgA by the M cell

made by plasma cells that secrete dimeric IgA

formed by cleavage of an epithelial cell receptor used to transport the dimeric IgA across the epithelial cell

made by T cells

Clonal selection theory

Side chain theory

Indirect template theory

Direct template theory

IgD type

IgE type

IgA type

IgG type

Major antibody in serum

Activates or fixes complement

First antibody type produced against an antigen during the primary antibody response

Involved in opsonization

IgG

IgA

IgM

IgE

Both (a) and (b)

IgA

IgM

IgE

B cells that are stimulated via their surface bound antibody in the absence of T cell help to commit suicide

self reactive B cells are killed by CD8 T cells

it is impossible to generate a self-reactive antibody

self reactive B cells switch to IgA which is all secreted and not present in serum

Fc region of the antibody

light chain alone

Fab regions of the antibody

heavy chain alone

IgM

IgE

All are similar

IgG
