摘要
Information regarding immunocompetence of the adaptive immune system(AIS) in zebrafish Danio rerio remains limited.Here,we stimulated an immune response in fish embryos,larvae and adults using lipopolysaccharide(LPS) and measured the upregulation of a number of AIS-related genes(Rag2,AID,TCRAC,IgLC-1,mIg,sIg,IgZ and DAB) 3 and 18 h later.We found that all of the genes evaluated were strongly induced following LPS stimulation,with most of them responding at 8 d post fertilization.This confirms that a functional adaptive immune response is present in D.rerio larvae,and provides a window for further functional analyses.
Information regarding immunocompetence of the adaptive immune system （AIS） in zebrafish Danio rerio remains limited. Here, we stimulated an immune response in fish embryos, larvae and adults using lipopolysaccharide （LPS） and measured the upregulation of a number of AIS-related genes （Rag2, AID, TCRAC, IgLC-1, mIg, slg, IgZ and DAB） 3 and 18 h later. We found that all of the genes evaluated were strongly induced following LPS stimulation, with most of them responding at 8 d post fertilization. This confirms that a functional adaptive immune response is present in D. rerio larvae, and provides a window for further functional analyses.
