✦ Synopsis

Recently, Kanbe and Cutler [1] reported that the a-linked oligo-o-mannosyl sidechains of a cell-wall o-mannan of the pathogenic yeast Candida albicans is in large part responsible for the binding of yeast cells to the marginal zone of mouse spleen. Stratford [2] also noted the importance of a-linked oligo-D-mannosyl side-chains of cell wall D-mannan in the mechanism of several types of yeast flocculation. Furthermore, Nelson and co-workers [3,4] reported that the alkali-released a-linked D-manno-oligosaccharides obtained from a C. albicans cell-wall D-mannan were potent inhibitors of lymphoproliferation induced by the parent D-mannan. These facts seem of interest from the viewpoints of both host-parasite interactions and the biological roles of carbohydrates.

The outer chain moiety of many yeast D-mannans has a long backbone consisting solely of a-(1 ~ 6)-linked o-mannopyranose units to which are attached many sidechains containing various kind of linkages attached to 0-2 of D-mannopyranose residues * Corresponding author.
