Cytosolic free calcium changes induced by chemotactic peptide in neutrophils from patients with chronic granulomatous disease.
Cytoplasmic free calcium concentration (Ca2+)i was measured in neutrophils from patients with the classical X-linked form of chronic granulomatous disease (CGD) by trapping the fluorescent calcium indicator Quin 2 in intact cells. CGD neutrophils do not produce superoxide and are only slightly depolarized upon stimulation by the chemotactic peptide. N-formyl-methionyl-leucyl-phenylalanine (FMLP...
متن کاملDeficiency in immune complex uptake by chronic granulomatous disease neutrophils.
Receptor-mediated binding and endocytosis by normal and chronic granulomatous disease (CGD) polymorphonuclear (PMN) leucocytes have been investigated. Our results suggest that activation of the respiratory burst is a requisite for normal immune complex internalization. Cell-associated immune complexes were detected by fluorescence microscopy, electron microscopy and flow cytometric techniques. ...
متن کاملChronic Granulomatous Disease, Case Report and Review of Literature
Chronic granulomatous disease (CGD) is a rare inherited disorder characterized by inability of phagocytes to generate oxygen radicals needed for intracellular killing of phagocytic microorganisms. We report a 2.5-year-old Iranian female with multiple liver abscesses. She was admitted in surgical ward because of abdominal pain and fever for one month duration that had no response to conventio...
متن کاملEffects of phorbol myristate acetate on the metabolism and ultrastructure of neutrophils in chronic granulomatous disease.
Previous investigations have demonstrated that phorbol myristate acetate (PMA), the active principle of croton oil, stimulates alterations in normal polymorphonuclear leukocytes (PMN) that resemble closely the changes that develop in the cells after phagocytosis of bacteria. The present study has compared the effects of PMA and heat-killed bacteria on the oxygen uptake, glucose oxidation, nitro...
متن کاملOsteomyelitis and lung abscess due to Aspergillus fumigatus in a chronic granulomatous disease patient
Background and Purpose: Chronic granulomatous disease (CGD) is an inherited disorder of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. This disorder results in recurrent life-threatening bacterial and fungal infections. Aspergillus species are the most common fungal infections in these patients. Case Report: Herein, we present a case of fungal infection in a girl wi...
