人类AB0血型决定因素是简单的碳水化合物结构,在自然界中广泛分布。关于A和B抗原的结构已经做了很多工作,但对抗A和抗B免疫反应的调节知之甚少。为了建立一个模型系统,我们对正常Balb/c小鼠的AB0免疫进行了鉴定,发现血清中有显著水平的天然抗-A,但几乎没有抗-B。这一发现以及在Balb/c小鼠产生的免疫抗-A中已知的IgM优势表明,该品系小鼠的AB0免疫水平与人B血型个体相当。用人红细胞免疫Balb/c小鼠后,正常小鼠和无淋巴细胞Balb/c小鼠产生相似水平的抗-A,表明抗-A反应不依赖于T细胞。此外,在CBA/XID小鼠中没有产生抗A或抗B抗体,表明存在2型T细胞非依赖性免疫反应。这些结果可能有助于更好地理解人类AB0反应,并建立小鼠作为研究AB0抗原免疫生物学的合适模型。
The human AB0 blood group determinants are simple carbohydrate structures which are widely distributed in nature. Much work has been done on the structure of the A and B antigens but little is known on the regulation of anti‐A and anti‐B immune responses. To develop a model system, we have characterized the AB0 immunity of normal Balb/c mice and found a significant level of serum natural anti‐A but almost no anti‐B. This finding and the known IgM predominance among immune anti‐A produced in the Balb/c mouse indicate that the AB0 immunity of this mouse strain is comparable to the one of human blood group B individuals. Following immunization with human red blood cells, similar levels of anti‐A were produced in normal and athymic Balb/c mice showing that the anti‐A response is T cell independent. Furthermore, no anti‐A or anti‐B antibodies were produced in CBA/xid mice indicating a type 2 T‐cell‐independent immune response. These results may contribute to a better understanding of human AB0 responses and establish the mouse as a suitable model to study the immunobiology of AB0 antigens.
