What does Th-1 secrete? activate? what inhibits it?
Secretes IFN-y
Activates macs & CD8 (CTLs)
Inhibited by IL-4, IL-10 (from Th-2 cell)
What does Th-2 secrete? activate? what inhibits it?
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)
Define acute phase reactants
factors whose serum [ ] change significantly in response to inflammation => produced by liver in both acute & chronic inflammatory states
What induces production of acute phase reactants?
IL-6, IL-1, TNF-alpha, IFN-y
What acute phase reactants are upregulated in inflammatory states? what is the result?
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
What acute phase reactants are downregulated in inflammatory states? what is the purpose?
Albumin => reduction conserves AA for positive reactants
Transferrin => internalized by macrophages to sequester iron
C3 deficiency has what affects?
Increases risk of severe, recurrent pyogenic sinus and respiratory tract infections;
increases susceptibility to type III hypersensitivity reactions.
What is contraindicated in C1 esterase inhibitor deficiency?
ACE inhibitors

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