Background: Cutaneous leishmaniasis (CL) is a serious public health problem in many tropical countries. The infection is caused by a protozoan parasite of Leishmania genus transmitted by Phlebotominae sandflies. In the present study, we constructed a eukaryotic expression vector to produce a fusion protein containing LmSTI1 from Leishmania major (L. major) and PpSP42 from Phlebotomus papatasi (...

background: hepatitis delta virus (hdv) is a subviral human pathogen that exploits host rna editing activity to produce two essential forms of the sole viral protein, hepatitis delta antigen (hdag). editing at the amber/w site of hdv antigenomic rna leads to the production of the large form (l-hdag), which is required for rna packaging. methods: in this study, pcr-based site-directed mutagenesi...

Abstract Background Hepatocellular carcinoma (HCC) is one of the most common cancers with high incidence and mortality. However, underlying mechanisms HCC still remain unclear. Eukaryotic translation initiation factors (eIFs) have a substantial effect on tumor development. In this study, we were aimed to investigate role eukaryotic factor 4 gamma 2 (EIF4G2) in HCC. Methods Western blot (WB) 30 ...

conclusions the results of this study demonstrated that the tpasp-padre-truncated orf2 gene cassette and the truncated orf2 gene in recombinant plasmids are successfully expressed in eukaryotic cells. the immunogenicity of the two recombinant plasmids with different formulations will be evaluated as a novel dna vaccine in future investigations. results sequence analysis and bioinformatics studi...

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...

Epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant DNA techniques. The aim of this study was to sub-clone the peroxisomal protein (PEP) cDNA into a mammalian expression vector leading to the formation of a  chimeric PEP-cDNA containing the FLAG epitope. The FLAG-PEP recombinant cDNA was construc...
