Functions of Eosinophils.

http://en.wikipedia.org/wiki/Eosinophil_granulocyte

Following activation, eosinophils effector functions include production of:

• cationic granule proteins and their release by degranulation.
• reactive oxygen species such as hypobromite, superoxide, and peroxide (hypobromous acid, which is preferentially produced by eosinophil peroxidase).
• lipid mediators like the eicosanoids from the leukotriene (e.g., LTC₄, LTD₄, LTE₄) and prostaglandin (e.g., PGE₂) families.
• enzymes, such as elastase.
• growth factors such as TGF beta, VEGF, and PDGF.
• cytokines such as IL-1, IL-2, IL-4, IL-5, IL-6, IL-8, IL-13, and TNF alpha.
