In Vitro production of tumor necrosis factor by murine splenic macrophages stimulated with mannoprotein constituents of Candida albicans cell wall

Abstract

Mannoprotein components from Candida albicans were investigated for their ability to induce production of tumor necrosis factor (TNF) by cultured splenocytes from naive or Candida-infected mice. Two chromatographically separated mannoproteins preparations, designated F1 and F2, were as able as the heat-inactivated Candida cells to induce the production of TNF from splenocytes of naive animals. In addition, they caused a significant augmentation of basic TNF secretion by splenocytes of Candida-infected animals. Experiments using plastic and/or nylon wool adherence, as well as treatments with antibodies depleting T or NK cells, consistently indicated that most if not all TNF was produced by splenic macrophages. In cultures of splenocytes from Candida-infected mice, mannoprotein addition also stimulated interferon-gamma (IFN-gamma) production by Thy 1.2 positive cells. Depletion of these cells or addition of anti-IFN-gamma antibodies abolished IFN production and reduced TNF secretion by adherent cells to the levels found in the cultures of mannoprotein-stimulated spleen cells from naive mice. These data add further evidence to the immunomodulatory properties possessed by some cell wall constituents of the human commensal microorganism C. albicans and suggest that IFN-gamma is endowed with a regulatory role in TNF production by mouse macrophages in vitro.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
