Physiological Consequences of Altering Gene Expression
CCR3 receptor knockout mice lack allergen-induced eosinophil accumulation in the esophagus normally seen with the wild-type eosinophilic esophagitis mouse model.
Species:  Mouse
Tissue: 
Technique:  Gene targeting in embryonic stem cells.
References:  6
CCR3 receptor knockout mice with induced pulmonary inflammation exhibit reduced trafficking of eosinophils from the blood into the lung parenchyma and increased numbers of intraepithelial mast cells in the trachea. Cholinergic stimulation resulted in airway hyperresponsiveness.
Species:  Mouse
Tissue: 
Technique:  Gene targeting in embryonic stem cells.
References:  21
CCR3 knockout mice with induced skin inflammation exhibit impaired recruitment of eosinophils to lung parenchyma and bronchoalveolar lavage. Cholinergic stimulation did not result in airway hyperresponsiveness.
Species:  Mouse
Tissue: 
Technique:  Gene targeting in embryonic stem cells.
References:  28
CCR3 receptor knockout mice have decreased levels of eosinophils in the blood, spleen and jejunum. Following induced inflammation, the knockout mice exhibit a 6-fold increase in the number of eosinophils in the blood compared to the wild-type.
Species:  Mouse
Tissue: 
Technique:  Gene targeting in embryonic stem cells.
