E2 protein, including hypervariable region 1 (HVR1) in the N-terminal region, contains some epitopes that can induce neutralizing antibodies.

包括高变区的E2蛋白含有中性抗，能诱导机体产生中性抗体。

After the tolerizing regimen, the host is withdrawn from the suppressive agents, but is able to maintain specific immune tolerance to the immunogenic epitopes present on the toleragen.

在致耐受方，免疫抑制剂从宿主撤离，宿主仍能保持对存在于耐受上的免疫性的特异性免疫耐受。
