Abstract

Natural killer (NK) activity is increased in both spleen and lung early in pulmonary infection by murine Chlamydia trachomatis in both susceptible nude and resistant heterozygous (nu/+) mice. Ablation of the rise in NK activity by giving the mice antiasialo GM-1 antibody or stimulation of NK activity by immunomodulators did not affect quantitative tissue counts of the mouse pneumonitis biovar of C. trachomatis or significantly affect survival. Studies are needed to further define the role of NK cells in host defense, immunoregulation, and immunopathology during chlamydial infection.

摘要

在易感性裸鼠和抗性杂合子(nu/+)小鼠中,鼠沙眼衣原体肺部感染早期,脾脏和肺中的自然杀伤(NK)活性均会升高。给小鼠注射抗唾液酸GM-1抗体消除NK活性的升高,或用免疫调节剂刺激NK活性,均不影响沙眼衣原体小鼠肺炎生物变种的定量组织计数,也未显著影响存活率。需要开展研究以进一步明确NK细胞在衣原体感染期间宿主防御、免疫调节和免疫病理学中的作用。
