Abstract

Immune adherence assays revealed that 10 out of 18 melanoma patients had demonstrable antibody to surface antigens of autologous cultured melanoma cells, with serum titers ranging from 1/4 to 1/160. Autologous fibroblasts showed no reactions with these sera. Antibody from individual patients showed reproducible temperature preference for maximal reactivity. Two new melanoma antigenic systems were defined in this study. The first, BD, was restricted to autologous melanoma and could not be demonstrated in absorption tests on 12 allogeneic melanoma cell lines. The other, AH, was found on 5 of 12 melanomas and represents a class of shared melanoma surface antigens. Neither BD nor AH antigen was found on normal cells from autologous, allogeneic, or xenogeneic sources or on any nonmelanoma tumor cell line. Methods are now available to develop a comprehensive serological classification of the surface antigens of melanoma.

摘要

免疫黏附试验显示,18名黑色素瘤患者中有10名对自体培养的黑色素瘤细胞表面抗原有可检测到的抗体,血清滴度范围为1/4至1/160。自体成纤维细胞与这些血清无反应。来自个体患者的抗体显示出对最大反应性具有可重复的温度偏好。本研究定义了两个新的黑色素瘤抗原系统。第一个是BD,仅限于自体黑色素瘤,在对12种同种异体黑色素瘤细胞系的吸收试验中未得到证实。另一个是AH,在12种黑色素瘤中的5种中发现,代表一类共享的黑色素瘤表面抗原。在来自自体、同种异体或异种来源的正常细胞以及任何非黑色素瘤肿瘤细胞系上均未发现BD或AH抗原。现在已有方法可用于对黑色素瘤表面抗原进行全面的血清学分类。
