Capsular polysaccharides of Cryptococcus neoformans

Rev Infect Dis. Sep-Oct 1984;6(5):619-24. doi: 10.1093/clinids/6.5.619.


Polysaccharides of Cryptococcus neoformans are considered to have a role in the virulence of this encapsulated fungus. The structure has been determined for the most abundant polysaccharide, a glucuronoxylomannan of varying xylose and ester content. The structural complexity of the capsular material increases from serotype D to A to B to C, but even for the simplest capsule (type D), the immunodeterminants seem to occur only on the side chains. The interactions of some of these groups with antibodies is discussed.
