Mucosal and systemic candidiasis in IL-8Rh-/- BALB/c mice.

چکیده
Germ-free BALB/c mice, genetically engineered to be deficient for interleukin-8 (IL-8) receptor homolog (IL-8Rh-/-), were more susceptible to gastric candidiasis after oral challenge and to acute systemic candidiasis after intravenous challenge than IL-8Rh+/+ controls. In comparison to IL-8Rh+/+ mice, the IL-8Rh-/- mice had slower influx of polymorphonuclear neutrophils (PMN) into Candida albicans-infected tissues and a lower percentage of PMN in peritoneal exudate cells (PEC) elicited with heat-killed C. albicans. PEC from IL-8Rh-/- mice exhibited less luminol-dependent chemiluminescence in response to C. albicans and did not kill C. albicans hyphae as well as PEC from IL-8Rh+/+ mice. C. albicans-colonized IL-8Rh-/- mice showed no histological evidence of systemic candidiasis. These results suggest a role for the IL-8Rh in murine resistance to gastric and acute systemic candidiasis, but not in resistance to systemic candidiasis of endogenous origin.

Efficacy of Spirulina platensis on immune functions in cancer mice with systemic candidiasis
The aim of this study was to investigate the immunomodulatory effects of Spirulina platensis (S.platensis) by measuring the levels of serum interleukin (IL)-4, IL-10, IL-17, tumor necrosis factor(TNF)-α and interferon (IFN)-|γ| in mice suffered from systemic candidiasis and breast cancer. Theaqueous extract of S. platensis was selected for this study. Balb/C female mice were inoculated withCand...
متن کاملNatural history of renal scarring in susceptible mIL-8Rh-/- mice.
BACKGROUND Urinary tract infections (UTIs) cause end-stage renal disease (ESRD) but the molecular mechanisms have remained unclear. Recently, the interleukin (IL)-8 receptor was shown to control disease susceptibility in mice and low IL-8 receptor expression was observed in pyelonephritis-prone patients. METHODS Intravesical Escherichia coli infection was established in mIL-8Rh-/- or Balb/c c...
متن کاملIn vitro lymphoproliferative response and cytokine production in mice with experimental disseminated candidiasis
Objective(s): Systemic candidiasis is an infection of Candida albicans (C. albicans) causing disseminated disease and sepsis, invariably when host defenses are compromised. We investigated the histopathological changes as well as the lymphoproliferative responses and cytokine production of splenic cells after stimulation with Concanavalin A (Con A) and Pokeweed mitogen (PWM) in mice with dissem...
متن کاملColonization of congenitally athymic, gnotobiotic mice by Candida albicans.
Colony counts, scanning electron microscopy, and light microscopy were used to assess the capacity of Candida albicans to colonize (naturally) and infect the alimentary tract of adult and neonatal (athymic [nu/nu] or heterozygous [+/nu] littermates) germfree BALB/c mice. When exposed to yeast-phase C. albicans, the alimentary tract of adult germfree mice (nu/nu or +/nu) is quickly (within 24 to...

Host protection against Candida albicans infection in a model of oral candidiasis involving infection-prone [DBA/2 (H-2(d))] and less infection-prone [BALB/c (H-2(d))] mouse strains was analyzed in terms of antibody and cellular responses, and in terms of cytokine patterns from regional lymph node cells. There was a selective expansion of gamma/delta(+) T-cell receptor cells, which correlated w...
