Abstract

Interferon (IFN) production by human peripheral lymphocytes stimulated with M. pneumoniae was investigated. The hydrogen peroxide released from M. pneumoniae was responsible for the induction of IFN from lymphocytes, since horseradish peroxidase inhibited the IFN production and abrogated the activity of IFN production in the supernatant of M. pneumoniae. The antiserum neutralizing IFN alpha and IFN beta failed to neutralize partially interferon produced by lymphocytes. Treatment either with pH 2.0 or antiserum neutralizing human IFN gamma resulted in a partial reduction of interferon. These results indicate that interferon produced by human lymphocytes stimulated with M. pneumoniae includes both types of IFN gamma and IFN beta.

摘要

研究了肺炎支原体刺激后人外周淋巴细胞产生干扰素(IFN)的情况。肺炎支原体释放的过氧化氢可诱导淋巴细胞产生IFN,因为辣根过氧化物酶可抑制IFN的产生,并消除肺炎支原体上清液中IFN的产生活性。中和IFNα和IFNβ的抗血清不能部分中和淋巴细胞产生的干扰素。用pH 2.0处理或用中和人IFNγ的抗血清处理,均可使干扰素部分减少。这些结果表明,肺炎支原体刺激人淋巴细胞产生的干扰素包括IFNγ和IFNβ两种类型。
