چکیده

The effect of recombinant granulocyte colony-stimulating factor (rG-CSF) on acute disseminated Candida albicans infection in nonneutropenic mice was investigated. Mice treated with a single dose of rG-CSF showed a significantly reduced mortality (28% vs. 90%; P < .001). The outgrowth of C. albicans from the kidneys, spleens, and livers of rG-CSF-treated mice was significantly reduced (log cfu/g of kidney, 5.54 vs. 7.13; P < .001), as were circulating tumor necrosis factor-alpha and interleukin-1beta. After rG-CSF, the kidneys showed fewer infectious infiltrates, enhanced granulocyte influx, and almost complete absence of hyphal outgrowth. During peritoneal C. albicans infection, rG-CSF enhanced influx of granulocytes to the site of infection, and exudate granulocytes showed increased oxygen radical production. These results indicate that rG-CSF enhances host resistance to disseminated candidiasis in nonneutropenic mice through activation of granulocytes and their recruitment to the site of infection.

Lactoferrin peptide increases the survival of Candida albicans-inoculated mice by upregulating neutrophil and macrophage functions, especially in combination with amphotericin B and granulocyte-macrophage colony-stimulating factor.

To develop a new strategy to control candidiasis, we examined in vivo the anticandidal effects of a synthetic lactoferrin peptide, FKCRRWQWRM (peptide 2) and the peptide that mimics it, FKARRWQWRM (peptide 2'). Although all mice that underwent intraperitoneal injection of 5 x 10(8) Candida cells with or without peptide 2' died within 8 or 7 days, respectively, the survival times of mice treated...

Efficacy of liposomal amphotericin B combined with gamma interferon or granulocyte-macrophage colony-stimulating factor for treatment of systemic zygomycosis in mice.

Granulocyte-macrophage colony-stimulating factor enhanced the efficacy of liposomal amphotericin B (LAMB) in a murine model of disseminated infection by Rhizopus oryzae, significantly prolonging survival and reducing tissue burden. The use of gamma interferon (IFN-gamma) alone was ineffective, and IFN-gamma combined with LAMB did not improve the results obtained with LAMB alone.

Treatment of intra-abdominal abscesses caused by Candida albicans with antifungal agents and recombinant murine granulocyte colony-stimulating factor.

The aim of the present study was to assess the influence of immunomodulation of host defense with recombinant murine granulocyte colony-stimulating factor (rmG-CSF) on intra-abdominal abscesses caused by Candida albicans. Mice received prophylaxis or therapy with 1 microg of rmG-CSF/day in the presence or absence of antifungal treatment consisting of amphotericin B (0.75 mg/kg of body weight/da...

"Emergency" granulopoiesis in G-CSF-deficient mice in response to Candida albicans infection.

Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein believed to play an important role in regulating granulopoiesis both at steady state and during an "emergency" situation. Generation of G-CSF and G-CSF receptor-deficient mice by gene targeting has demonstrated unequivocally the importance of G-CSF in the regulation of baseline granulopoiesis. This study attempted to define the phy...

IL-1 Coordinates the Neutrophil Response to C. albicans in the Oral Mucosa

Mucosal infections with Candida albicans belong to the most frequent forms of fungal diseases. Host protection is conferred by cellular immunity; however, the induction of antifungal immunity is not well understood. Using a mouse model of oropharyngeal candidiasis (OPC) we show that interleukin-1 receptor (IL-1R) signaling is critical for fungal control at the onset of infection through its imp...
