Oral immunization with a recombinant cysteine-rich section of the Entamoeba histolytica galactose-inhibitable lectin elicits an intestinal secretory immunoglobulin A response that has in vitro adherence inhibition activity.

By D E Beving, C J Soong and J I Ravdin

Abstract

The LC3-encoded 52-kDa recombinant protein includes amino acids 758 to 1134 of the 170-kDa subunit of the galactose-inhibitable lectin. Oral immunization of BALB/c mice with the LC3-encoded protein and cholera holotoxin induced an intestinal secretory immunoglobulin A (IgA) response (P < 0.01 compared with the control). There was a negative correlation (P = 0.001) between intestinal anti-LC3 IgA and serum IgA and IgG antibody responses. Intestinal secretions from immunized mice completely inhibited the galactose-specific adherence of axenic trophozoites ot Chinese hamster ovary cells (P < 0.01)
