Comparative analysis of the phenotypic characteristics of neutrophils from patients with specific granule deficiency and mice deficient for C/EBPϵ protein.
Phenotypic Characteristics . | Specific Granule Deficiency . | C/EBPϵ Knockout Mouse . |
---|---|---|
Clinical Presentation | Multiple bacterial infections | Bacterial infections and MDS-like disorder |
Neutrophil morphology | Bilobed nuclei | Bilobed nuclei |
Absent 20 granules by Wright staining | Absent 20 granules by Wright staining | |
Absent eosinophils by Wright staining | Absent eosinophils by Wright staining | |
Neutrophil migration | Decreased (by Rebuck skin window) | Decreased (by thioglycollate challenge) |
Disaggregation | Decreased | Not tested |
Phagocytosis | Normal | Decreased |
Superoxide generation: | ||
PMA | Decreased | Decreased |
A23187 | Decreased | Not tested |
Fmet-leu-phe | Normal | Not tested |
Bactericidal activity | Decreased | Decreased |
