# Mediators of inflammation are all EXCEPT:
A. TNF
B. IFN
C. PG
D. Myeloperoxidase
The correct answer is D. Myeloperoxidase.
Myeloperoxidase is not an inflammatory mediator. It is an enzyme in neutrophils that convert Cl-, I- and SCN- ions to corresponding acids -HOCl etc. These acids are potent oxidants and help in destroying the invading organisms.
