Abstract

The classes of immunoglobulin-containing cells in the lungs of mice after primary infection with Sendai virus were studied using an indirect immunofluorescence technique. It was found that during the first 5 days of the infection there was a considerable increase in all classes of immunoglobulin-containing cells with the IgA-containing cells retaining their pre-infection predominance. By the 6th day of the infection both IgG and IgA cells were present in equal numbers. This 1:1 ratio persisted for nearly 30 days and was followed by a gradual reversion to IgA excess. IgM-containing cells represented only 1/15–1/30 of all immunoglobulin-containing cells at any time during the infection.

摘要

利用间接免疫荧光技术研究了仙台病毒初次感染后小鼠肺中含免疫球蛋白细胞的类别。结果发现,在感染的前5天,所有含免疫球蛋白细胞的数量都有显著增加,其中含IgA的细胞保持了感染前的优势地位。到感染第6天,IgG细胞和IgA细胞数量相等。这种1:1的比例持续了近30天,随后逐渐恢复到IgA过量。在感染期间的任何时候,含IgM的细胞仅占所有含免疫球蛋白细胞的1/15 - 1/30。
