Physiological Consequences of Altering Gene Expression
CCR4 receptor knockout mice exhibit decreased mortality upon administration of high or low dose bacterial lipopolysaccharide.
Species:  Mouse
Tissue: 
Technique:  Gene targeting in embryonic stem cells.
References:  4
Following infection with A. fumigatus spores, CCR4 receptor knockout mice exhibit increased numbers of airway neutrophils and macrophages, as well as reduced numbers of peribronchial and airway eosinophils. Cholinergic stimulation induces airway hyperresponsiveness, which then subsides to a lower level in the knockout mice than wild-type. The elimination of the pathogen from the knockout mice was more rapid compared to the wild-type.
Species:  Mouse
