溶组织内阿米巴感染是发展中国家的一个重要卫生问题。急性阿米巴结肠炎是其最常见的表现,需由阿米巴滋养体对结肠粘膜上皮细胞及肠粘蛋白的粘附而致病。在体外,此附着过程是通过滋养体的一种可抑制半乳糖的植物血凝素170kDa亚单位介导的,这种半乳糖特异的粘附在体外可被针对植物血凝素170kDa亚单位单抗所抑制。已发现作为重组融合蛋白表达的170kDa亚单位的富 Entamoeba histolytica infection is an important health problem in developing countries. Acute amebic colitis is its most common manifestation and is caused by the adhesion of amoebae to colonic mucosal epithelial cells and intestinal mucin. In vitro, this attachment process is mediated through a 170 kDa subunit of the trophozoite that inhibits galactose, which galactose-specific adhesion can be targeted in vitro to the 170 kDa subunit of phytohemagglutinin Anti-suppressed. The 170 kDa subunit abundance has been found to be expressed as a recombinant fusion protein
