研制了针对免疫优势的HHV-6(GS分离株)晚期和早期蛋白的单抗。主要的晚期蛋白被鉴定为一种可能的糖蛋白,其分子量约为110 kDa(GP 110)。早期抗原的免疫印迹分析得到41和38 kDa的蛋白(p41/38)。抗HHV-6早期蛋白的单抗与14株不同HHV-6分离株感染的细胞发生反应。相反,针对晚期蛋白的单抗只与其中10个分离物发生反应,表明该糖蛋白存在菌株变异。不同献血员血清中gp110抗体阳性率在56%~96%之间。相比之下,除了非洲伯基特淋巴瘤(ABL)和霍奇金病(HD)患者的血清外,只有10%-30%的血清p41/38抗体阳性。这些抗体模式表明在ABL和HD患者中存在活跃的HHV-6复制。
Monoclonal antibodies (MAbs) were developed against immunodominant HHV‐6 (GS isolate) late and early proteins. The major late protein was identified as a probable glycoprotein with a molecular weight of approximately 110 kDa (gp 110). Immunoblotting of the early antigen yielded proteins of 41 and 38 kDa (p41/38). The MAb to the early protein reacted with cells infected with 14 different HHV‐6 isolates. In contrast, the MAb against the late protein reacted with only 10 of these isolates, indicating that there was strain variation in this glycoprotein. The percentage of antibody‐positive sera reactive with gp110 in the ELISA ranged from 56% to 96% among the different serum donor categories. In contrast, only 10‐30% of the sera were positive for antibodies to p41/38 with the exception of sera from patients with African Burkitt's lymphoma (ABL) and Hodgkin's disease (HD). These antibody patterns denote the presence of active HHV‐6 replication in patients with ABL and HD.
