39
Q

What does Th-2 secrete? activate? what inhibits it?

A

Secretes IL-4, 5, 6, 13
Recruits eosinophils for parasite defense & promotes IgE production by B cells
Inhibited by IFN-y (from Th-1 cell)

40
Q

Define acute phase reactants

A

factors whose serum [ ] change significantly in response to inflammation => produced by liver in both acute & chronic inflammatory states

41
Q

What induces production of acute phase reactants?

A

IL-6, IL-1, TNF-alpha, IFN-y

42
Q

What acute phase reactants are upregulated in inflammatory states? what is the result?

A

Serum Amyloid A => prolonged elevation leads to amyloidosis
CRP => opsonin; fixes complement & facilitates phagocytosis & measure of ongoing inflammation
Ferritin => binds & sequesters Fe++ to inhibit microbial Fe+ scavenging
Fibrinogen => Coag factor; promotes endothelial repair; correlates w/ ESR
Hepcidin => prevents release of Fe+ bound by ferritin indicating anemia of chronic dz

43
Q

What acute phase reactants are downregulated in inflammatory states? what is the purpose?

A

Albumin => reduction conserves AA for positive reactants

Transferrin => internalized by macrophages to sequester iron

44
Q

C3 deficiency has what affects?

A

Increases risk of severe, recurrent pyogenic sinus and respiratory tract infections;
increases susceptibility to type III hypersensitivity reactions.

45
Q

What is contraindicated in C1 esterase inhibitor deficiency?

A

ACE inhibitors

46
Q

What is the result of DAF (GPI anchored enzyme) deficiency?

A

Causes complement-mediated lysis of RBCs & paroxysmal nocturnal hemoglobinuria.

47
