Abstract

Cholera toxin added into cell cultures together with human leukocyte interferon inhibited the establishment of the antiviral state by interferon but not the anticellular activity of interferon in human cells. Sensitivities of various human cell lines to anticellular activities of interferon and cholera toxin were compared, but no direct correlation between both activities were demonstrated. These results suggest that antiviral and anticellular activities of interferon are due to different mechanism of actions, and cholera toxin does not act directly on the receptor site for interferon.

摘要

将霍乱毒素与人白细胞干扰素一同添加到细胞培养物中,可抑制干扰素建立抗病毒状态,但不会抑制干扰素在人体细胞中的抗细胞活性。比较了各种人类细胞系对干扰素和霍乱毒素抗细胞活性的敏感性,但未证明两者活性之间存在直接相关性。这些结果表明,干扰素的抗病毒和抗细胞活性是由不同的作用机制引起的,并且霍乱毒素不会直接作用于干扰素的受体位点。
