Airway remodelling in asthma: from benchside to clinical practice. Can Respir J 17 4 :e85— Airway structural alterations selectively associated with severe asthma. However, although eosinophilia commonly accompanies helminthic infections and eosinophils are toxic to helminths in vitro, there is no direct evidence that they kill parasites in vivo. Although they are phagocytic, eosinophils are less efficient than neutrophils in killing intracellular bacteria.

Eosinophils may modulate immediate hypersensitivity reactions by degrading or inactivating mediators released by mast cells, such as histamine, leukotrienes which may cause vasoconstriction and bronchoconstriction , lysophospholipids, and heparin. Eosinophil production appears to be regulated by T cells through the secretion of the hematopoietic growth factors granulocyte-macrophage colony-stimulating factor GM-CSF , interleukin-3 IL-3 , and interleukin-5 IL Eosinophil granules contain major basic protein and eosinophil cationic protein; these proteins are toxic to several parasites and to mammalian cells.

These proteins bind heparin and neutralize its anticoagulant activity. Eosinophil-derived neurotoxin can severely damage myelinated neurons. Eosinophil peroxidase, which differs significantly from peroxidase of other granulocytes, generates oxidizing radicals in the presence of hydrogen peroxide and a halide.

Charcot-Leyden crystals are primarily composed of phospholipase B and are located in sputum, tissues, and stool in disorders in which there is eosinophilia eg, asthma Asthma Asthma is a disease of diffuse airway inflammation caused by a variety of triggering stimuli resulting in partially or completely reversible bronchoconstriction. Symptoms and signs include dyspnea Peripheral blood eosinophilia Peripheral eosinophilia is characterized as.

Diurnal levels vary inversely with plasma cortisol levels; the peak occurs at night and the trough in the morning. CCR3, the receptor for CCL11 , which allow them to respond to a multitude of cytokines, chemokines and lipid mediators.

Eosinophils are recruited from the blood into the tissues at sites of inflammation. Upon activation eosinophils can release an array of inflammatory mediators Figure 1.
