摘 要:为观察鸡防御素Gal-13对雏鸡淋巴细胞增殖功能的影响,以Gal-13为研究对象,在体外培养雏鸡淋巴细胞,运用MTT法首先研究不同质量浓度的Gal-13对抗原刺激的雏鸡外周血淋巴细胞增殖功能的影响,然后选取1mg/L的Gal-13饲喂雏鸡,观察其各免疫器官和外周血淋巴细胞增殖功能的变化。结果发现:体外Gal-13(0.625~1.250mg/L)提高淋巴细胞的增殖功能,但过高剂量的Gal—13(5~10mg/L)抑制淋巴细胞的增殖。1mg/L的Gal-13能够提高雏鸡中枢免疫器官淋巴细胞增殖功能,抑制脾脏淋巴细胞的增殖功能。结果表明,Gal-13能够提高中枢免疫器官的免疫反应,对免疫器官的作用具有一定选择性。The effect of different concentration of Gal-13 on the proliferation of peripheral blood lymphocyte of the chickens stimulated by mitogen by MTT in vitro firstly was observed. Gal-13(1 mg/L)was fed to chicken, the lymphocyte proliferation of immune organs and peripheral blood were determined. Results showed that:In vitro ,Gal- 13 (0. 625-1. 250 mg/L) enhanced the proliferation of peripheral blood lymphocyte of the chickens stimulated by lipopolysaccharide (LPS) and concanavlin A (ConA) ,but high dose of Gal-13 (5-10 mg/L) restrained its proliferation (P〈0.01). In vivo experiments, compared to the control, Gal-13 (1 mg/L) promoted the proliferation of lymphocyte in central immune organ, but restrained the lymphocyte proliferation in spleen. These results indicated Gal-13 could enhance immune responses of central immune organ and had the activity of tissue-specific selection.
