infectious bursal disease (ibd) is an economically important viral disease of chickens with worldwide distribution which suppresses the immune system of young chickens. vp2 is the major host-protective protein of infectious bursal disease virus (ibdv). the encoding region of vp2 protein was pcr amplified from a plasmid containing a cdna fragment of large genomic segment of ibdv, strain d78. thi...

In this study, in order to facilitate and accelerate the production of eukaryotic protein alpha 1-antitrypsin (AAT) with correct post-translational modifications, a protein production system based on the transduction of CHO and COS-7 cells using lentiviral vectors was developed. Human AAT cDNA was cloned into a replication-defective lentiviral vector. The transgene AAT-Jred chimer was transferr...

vp2 gene coding region of a vaccinal strain (d78) of infectious bursal disease virus (ibdv) was clonedin a eukaryotic expression vector, psec tag2a. the gene was placed downstream of ig κ chain leadersequence, under the control of human cytomegalovirus (hcmv) immediate early enhancer and promoter. theconstruct psec tag2a-vp2 was transfected in cos-7 cell line and the expression and secretion of...

JC polyomavirus (JCV), the causative agent of progressive multifocal leukoencephalopathy (PML), is ubiquitous in humans, infecting children asymptomatically and then persisting in the kidney. Renal JCV is not latent but replicates to excrete progeny in the urine. The renal-urinary JCV DNAs carry the archetype regulatory region that generates various rearranged regulatory regions occurring in JC...

Interferon gamma (IFN-γ) is one of the key cytokines in defining T helper 1 lymphocyte immuneresponses. In this study, the bovine IFN-γ gene was cloned from spleen tissue RNA using the reversetranscription-polymerase chain reaction (RT-PCR). IFN-γ cDNA was sub-cloned and expressed inmammalian expression plasmid (pcDNA3.1(+)) under the control of the human cytomegalovirus (CMV)promoter. The pred...
