title: Characterization of effector cells with anti-Candida activity obtained from murine bone marrow cells cultured in the presence of rhG-CSF: comparison between normal and CY-treated mice.
abstract: Bone marrow cells (BMC) obtained from normal and cyclophosphamide (CY)-treated mice were cultured in the presence of recombinant human granulocyte-colony stimulating factor (rhG-CSF) and their effector cell activities inhibiting growth of C. albicans were examined. When BMC from CY-treated mice were preincubated with 0.05 ng/ml of rhG-CSF, effector cells with enhanced anti-C. albicans activity were recovered in the adherent cell population, whereas anti-C. albicans activity of BMC from normal mice was found in the non-adherent cell population. During culture without the presence of rhG-CSF, nonadherent BMC, seemingly granulocytes, from normal mice showed apoptotic change, but addition of rhGCSF clearly inhibited this change. On the other hand, when BMC from CY-treated mice were cultured with rhG-CSF, adherent cells as the main effector had the appearance of monocytes. These differences between the effectors with anti-C. albicans activity obtained from normal and CY-treated mice are discussed.
