Defective polymorphonuclear leukocyte metabolism and function in canine cyclic neutropenia.
Humans and grey collie dogs with cyclic neutropenia are known to suffer from an increased rate of bacterial infection. Because of the previously described microanatomic abnormalities of lysosome formation found in the polymorphonuclear leukocytes (PMNs) of dogs with canine cyclic neutropenia, studies of these cells were undertaken. PMNs from grey collie dogs were found to have significant metab...
متن کاملCyclic neutropenia.
Cyclic neutropenia is a rare hematologic disorder, characterized by repetitive episodes of fever, mouth ulcers, and infections attributable to recurrent severe neutropenia. Fluctuations in blood cells are due to oscillatory production of cells by the bone marrow. Recent genetic, molecular, and cellular studies have shown that autosomal-dominant cyclic neutropenia and sporadic cases of this dise...
متن کاملCyclic neutropenia in mammals.
Cyclic neutropenia (CN) has been well documented in humans and the gray collie. A recent model of the architecture and dynamics of hematopoiesis has been used to provide insights into the mechanism of cycling of this disorder. It provides a link between the cycling period and the cells where the mutated ELA2 is expressed. Assuming that the biologic defect in CN is the same in dogs, and the obse...
متن کاملTreatment of canine cyclic neutropenia by lentivirus-mediated G-CSF delivery.
Cyclic neutropenia is a rare disease that occurs both in humans and gray collie dogs and is characterized by recurrent severe neutropenia leading to bacterial infections and shortened life expectancy. Daily injections of recombinant granulocyte colony-stimulating factor (rG-CSF) are effective in shortening the period of severe neutropenia and reducing infections. After demonstrating that rG-CSF...
متن کاملCanine cyclic neutropenia: Erythropoietin and platelet cycles after bone marrow transplantation.
The marrow of a dog affected with cyclic neutropenia (CN) was transplanted into an unaffected supralethally irradiated litermate. Prompt engraftment occurred, and cyclic rises and falls in numbers of platelets, reticulocytes, and granulocytes were noted in the recipient soon after engraftment. Prior to transplantation and under hypoxic conditions, the donor had serum erythropoietin (ESF) peak l...
