An attempt was made to correlate murine cytomegalovirus-induced immuno-suppression with the presence of virus-infected cells in the spleen. For this purpose, SWR/J mice were infected with murine cytomegalovirus, and spleens were removed periodically and assayed for the presence of infectious centers in different cell populations and for their capacity to respond to mitogens. The maximal degree of immunosuppression correlated with the peak in adherent cell infectious centers. This was followed by a rapid rise in the number of cells per spleen (splenomegaly), a more gradual return to normal responsiveness to mitogens, and a rapid disappearance of infectious centers. These results add more support to the hypothesis that murine cytomegalovirus-induced immunosuppression is caused indirectly by infection of adherent spleen cells.
人们试图将鼠巨细胞病毒诱导的免疫抑制与脾脏中病毒感染细胞的存在联系起来。为此,用鼠巨细胞病毒感染SWR/J小鼠,并定期切除脾脏,检测不同细胞群体中感染中心的存在情况及其对有丝分裂原的反应能力。免疫抑制的最大程度与黏附细胞感染中心的峰值相关。随后脾脏细胞数量迅速增加(脾肿大),对有丝分裂原的反应能力逐渐恢复正常,感染中心迅速消失。这些结果进一步支持了以下假说:鼠巨细胞病毒诱导的免疫抑制是由脾脏黏附细胞感染间接引起的。
