Tc. Caesartonthat et Je. Cutler, A MONOCLONAL-ANTIBODY TO CANDIDA-ALBICANS ENHANCES MOUSE NEUTROPHIL CANDIDACIDAL ACTIVITY, Infection and immunity, 65(12), 1997, pp. 5354-5357
A monoclonal antibody (MAb) to Candida albicans (MAb B6.1) that protec
ts against candidiasis and the nonprotective MAB B6 were compared for
ability to support neutrophil (polymorphonuclear leukocyte [PMN]) cand
idacidal activity. Both MAbs are immunoglobulin M, and each recognizes
distinct C. albicans mannan cell wall determinants. PMN candidacidal
activity was assessed by transmission electron microscopy and by an in
vitro killing assay. The results indicated that MAB B6.1, but not MAb
B6, enhances ingestion and killing of yeast cells by PMN in the prese
nce of serum complement.
