Carbohydrate Name

Glucurunoxylomannan

Carbohydrate Class

Miscellaneous

Source Microbe

Cryptococcus neoformans Serotype A [strain 24064]

Basic Structure

The major component of C. neoformans capsular polysaccharide is glucurunoxylomannan [GXM] consisting of an unbranched mannose backbone substituted with xylose, glucuronic acid and O-acetyl residues

Proposed functions

C. neoformans has a large polysaccharide capsule that is a determinant of virulence. The capsular polysaccharide causes immunologic paralysis and inhibits phagocytosis by macrophages. Soluble C. neoformans capsular polysaccharide enhances human immunodeficiency virus [HIV] infection in cultured cells, suggesting a new pathogenic role in AIDS

Antigenic Nature used to produce antibodies

Glycoconjugates

Carrier Name

Tetanus toxoid

Conjugation Method

GXM was conjugated to tetanus toxoid using CDAP precipitation

Antibodies

Polysera

Antibody type and class

IgG [predominantly IgG1]

Assay System

ELISA
