Abstract

Characterization of interferon (IFN) induced by a second challenge with specific antigen was investigated during the development of hyporeactivity established after challenge of Mycobacterium bovis BCG-sensitized mice with BCG cell wall fraction (BCG-CW). When BCG-sensitized mice were challenged with BCG-CW, IFN-gamma was detected in the circulation 4 h later and rapidly disappeared. After IFN-gamma disappeared from their blood, mice became completely hyporeactive to the second challenge with BCG-CW for 1 day, and thereafter they recovered from this hyporeactive state. However, we always observed that IFN induced at first by the second challenge with BCG-CW during the hyporeactive state was type I IFN-alpha/beta, but thereafter was entirely IFN-gamma. Induction of IFN-alpha/beta by the specific antigen during restoration from the hyporeactive state in BCG-sensitized mice is discussed.

摘要

在卡介苗(BCG)致敏小鼠用卡介苗细胞壁成分(BCG-CW)攻击后建立低反应性的过程中,研究了第二次用特异性抗原攻击诱导的干扰素(IFN)的特征。当BCG致敏小鼠用BCG-CW攻击时,4小时后在循环中检测到IFN-γ,且其迅速消失。当IFN-γ从血液中消失后,小鼠对第二次BCG-CW攻击完全低反应1天,此后它们从这种低反应状态恢复。然而,我们始终观察到,在低反应状态下最初由第二次BCG-CW攻击诱导的IFN是I型IFN-α/β,但此后完全是IFN-γ。本文讨论了在BCG致敏小鼠从低反应状态恢复过程中特异性抗原对IFN-α/β的诱导作用。
