Abstract

We used an ELISPOT (enzyme-linked immunosorbent spot) assay to quantitate the long-term rotavirus-specific intestinal antibody response in a murine model. The frequency of murine intestinal antibody-secreting cells (ASCs) was followed for a period of 1 year after a single dose of rhesus rotavirus (10(6) PFU) was administered at 10 days of age. Some animals were boosted at that time with a second dose. One year after infection, virus-specific ASCs declined from acute-phase levels, but they were still present at significant levels (1.32 x 10(4) virus-specific ASCs per 10(6) intestinal mononuclear cells; approximately 17% of the previously reported response at 1 month after infection). A booster dose 1 year after the primary infection produced a 100% increase in virus-specific ASCs but did not restore the response to that of the primary infection.

摘要

我们使用酶联免疫斑点(ELISPOT)测定法在小鼠模型中定量长期轮状病毒特异性肠道抗体反应。在10日龄时给予单剂量恒河猴轮状病毒(10⁶ PFU)后,跟踪小鼠肠道抗体分泌细胞(ASC)的频率长达1年。当时一些动物用第二剂进行加强免疫。感染1年后,病毒特异性ASC从急性期水平下降,但仍以显著水平存在(每10⁶肠道单核细胞中有1.32×10⁴病毒特异性ASC;约为感染后1个月时先前报道反应的17%)。初次感染1年后的加强剂量使病毒特异性ASC增加了100%,但未将反应恢复到初次感染时的水平。
