Fig. 1 — This model shows the three basic components of the cell wall present in almost all fungal pathogens. Mannoproteins have polymers of mannose that decorate the proteins through O-linkages or N-linkages and are predominately found in the outer portion of cell wall. β-glucans are the most abundant constituent of the cell wall and tend to be in the middle with β-1,3-glucans forming the scaffold and β-1,6-glucans forming the branches, while chitin is found in the inner portion of the cell wall and linked to β-1,3-glucan. Other components of the cell wall in some fungi include α-glucan, galactomannan, chitosan, and melanin. In addition, the cryptococcal capsule is linked to the cell wall.
