IgA-antibody (AB) activities have been elicited in rat bile against several antigens such as bacteria, erythrocytes, tumour cells, haptens and proteins (Lemaître-Coelho, Jackson & Vaerman, 1978; Hall et al., 1979; Montgomery, Lemaître-Coelho & Vaerman, 1980; Peppard et al., 1982). However, their biological significance, except for plasma clearance of immune complexes (Peppard et al., 1982) and bacterial agglutination, remains conjectural, despite their possible major contribution to rat intestinal immunity. The importance of local intestinal immunity in protection against cholera is today widely admitted (Jertborn, Svennerholm & Holmgren, 1984). Intraintestinally given cholera toxin (CT) is a potent immunogen in rats whose intestinal mucosa then harbours numerous anti-CT IgA plasma cells (Pierce, 1978). Since bile IgA in rats is largely, but not entirely, derived from intestinal synthesis (Vaerman, Lemaître-Coelho & Jackson, 1978; Manning et al., 1984), rats intestinally immunized with CT could display high levels of anti-CT IgA AB in their bile, and these AB might neutralize CT in the biologically relevant intestinal loop assay (Lange & Holmgren, 1978).
针对多种抗原,如细菌、红细胞、肿瘤细胞、半抗原和蛋白质,大鼠胆汁中已诱导出IgA抗体(AB)活性(勒梅特 - 科埃略、杰克逊和瓦尔曼,1978年;霍尔等人,1979年;蒙哥马利、勒梅特 - 科埃略和瓦尔曼,1980年;佩珀德等人,1982年)。然而,除了免疫复合物的血浆清除(佩珀德等人,1982年)和细菌凝集作用外,它们的生物学意义仍然是推测性的,尽管它们可能对大鼠肠道免疫有重要贡献。如今,人们普遍承认局部肠道免疫在预防霍乱中的重要性(耶特伯恩、斯文纳霍尔姆和霍尔姆格伦,1984年)。肠道内给予霍乱毒素(CT)对大鼠是一种有效的免疫原,其肠道黏膜随后含有大量抗CT IgA浆细胞(皮尔斯,1978年)。由于大鼠胆汁中的IgA很大程度上但并非完全来自肠道合成(瓦尔曼、勒梅特 - 科埃略和杰克逊,1978年;曼宁等人,1984年),用CT进行肠道免疫的大鼠胆汁中可能会显示出高水平的抗CT IgA AB,并且这些AB可能在生物学相关的肠袢试验中中和CT(兰格和霍尔姆格伦,1978年)。
