標靶描述
Glucuronoxylomannan (GXM), a polysaccharide, is the principal constituent of the Cryptococcus neoformans capsule that modulates the inflammatory response of human monocytes in vitro and exerts many immunoregulatory effects. Its basic structure is a tri-mannose repeat with a glucuronic acid residue in the first mannose. Its structure is shown to be further modified in individual strains by the addition of xylose substitutions on the mannan backbone. Six triads known as M1-M2 are shown to be present in various proportions in GXM from the various serotypes and M2 is reported to be the most common triad in serotype A GXM. Soluble GXM serves as an important virulence factor and contributes to the pathogenesis of infection. High levels of GXM are found in serum of patients with cryptococcosis. Clone 3E5 is a class II monoclonal Abs that is reported to possess hydrolytic activity against a 12 amino acid P1 peptide (SPNQHTPPWMLK) at positions 1, 2, and 10. (Ref.: Bowen, A., et al. (2017). J. Biol. Chem. 292(2); 417-434; Tissi, L., et al. (2004). Infect. Immun. 72(11); 6367-6372; Lendvai, N., and Casadevall, A. (1999). J. Infect. Dis. 180(3); 791-801).
