摘要:

本研究旨在揭示BLec1、BNK及细胞因子在B21和B19两种单倍型鸡对马立克病(MD)抗性差异中的可能机制。分别对B21和B19单倍型1日龄鸡腹腔接种马立克病毒(MDV)超强毒株,在攻毒后不同时间检测鸡外周血淋巴细胞中BLec1、BNKIFN-γIL-4、IL-10和IL-18的基因转录水平。结果显示,在第4、7 天,两种鸡BNKBLec1和4种细胞因子水平表现出不同程度的降低。在第10天,B21单倍型鸡中BNKBLec1、IFN-γIL-4和IL-18基因转录量出现不同程度的升高,而B19单倍型鸡中细胞因子转录水平有所下降。在第13天,B21单倍型鸡中BNKBLec1、IL-18和IL-10基因转录量表现出不同程度的升高,而B19单倍型鸡中则有所下降。以上结果总体表明,MD耐受型鸡在感染沉默期BNKBLec1和细胞因子转录量高于敏感型,不同遗传基因型鸡对MD的抗性差异与耐受基因及细胞因子的转录情况有着密切的关系。

Abstract:

 This study was undertaken to reveal the possible resistance mechanism of B19 and B21 haplotype SPF chickens against MDV.One day-old B19 and B21 haplotype chickens were infected with MDV Md5 strain by intramuscular as 800 PFU per feather.The transcription levels of targets genes including BNKBLec1,IFN-γIL-4,IL-10 and IL-18 were measured at different time points after MDV treatment.Results showed that gene transcription levels of BNKBLec1 and the four cytokines in B19 and B21 chickens decreased compared to the control group on the 4th and 7th day post infection (dpi).On the 10th dpi,BNKBLec1, IFN-γIL-4 and IL-18 gene transcriptions highly increased in B21 chicken in different levels,while decreased in B19 chickens.On the 13th dpi,gene transcriptions of BNKBLec1,IL-18 and IL-10 in MDV treated B21 chickens also rose in different levels compared to the control group,while decreased in MDV treated B19 chickens.In conclusion,the present study demonstrate that B21 haplotype SPF chickens express high levels of BNKBLec1 and cytokines than B19 ones and the resistant difference against MD between MD tolerant and sensitive chickens is related to the gene transcriptions of BNKBLec1 and cytokines.
