Question 0

WHat are the effector molecules of humoral immunity?

Answer 0

Antibodies

Question 1

What does CD3 do?

Answer 1

mediates signal transduction functions from TCRs (T cell receptors) upon binding antigen from the MHC of an APC

Question 2

Fab Region

Answer 2

The portion of an antibody that contains a whole light chain, attached to the V and C domains of the heavy chain; this is the portion responsible for antigen recognition and antigen binding. (Fab = fragment, antigen binding)

Question 3

IgA
Secreted form?
Funciton

Answer 3

Secreted ass a dimer

fx = mucosal immunity

Question 4

IgD
Secreted form?
Fx?

Answer 4

No secreted form

Fx= naive B cell antigen receptor

Question 5

IgE
Secreted form?
Fx?

Answer 5

Secreted ass monomer

Fx= mast cell activation (hypersensitivity rxn) + parasite defense

Question 6

IgG
Secreted form?
Fx?

Answer 6

Secreted as monomer,
fx= opsonization, complement activation, ab dependant cell-mediated cytotoxicity, neonate immunity, B cell feedback inhibition

Question 7

IgM
Secreted?
Fx=

Answer 7

Secreted as Pentamer

fx= Naive B cell antigen receptor, complement activation
