Inhibition of zymosan-induced alternative complement pathway activation by concanavalin A

Infect Immun. 1982 Dec;38(3):1279-84. doi: 10.1128/iai.38.3.1279-1284.1982.

Abstract

Zymosan, a polysaccharide composed primarily of glucan and mannan residues, activates the complement system through the alternative complement pathway. We showed that zymosan-induced complement activation is inhibited by zymosan-bound lectins with carbohydrate specificities for mannosyl and glycosyl residues. Lectins unable to bind mannosyl or glucosyl residues did not inhibit zymosan-induced complement activation.
