To investigate the effect of CD300LG-γ induction on the cytotoxic activity of CIK. Eukaryotic expression plasmid hCD300LG-γ/pEGFP-C3, which can express human CD300LG-γ, was constructed and transfected into CHO cells by lipofectamine. The expression of CD300LG-γ was confirmed by immunofluorescence, RT-PCR, and Western Blot. To produce CIK cells, human peripheral blood mononuclear cells (PBMC) we...

Human neutrophil peptide-1 (HNP-1) is an important defense molecule in neutrophils and Sertoli cells and plays an important role in the blood-testis barrier. In this study, we investigated the behavior of Sertoli cells transfected with the HNP-1 gene and compared the ability of Sertoli cells and fibroblast cells to resist transfection. Total RNA was isolated from human blood. The DNA coding seq...

OBJECTIVES The basic HLH transcription factor Olig is a key regulator for differentiating the oligodendrocyte lineage cells during development. Oligodendrocyte transcription factor 2 (Olig2) plays a crucial role in differentiating the oligodendrocytes in the spinal cord. We aimed to construct and investigate the eukaryotic expression recombinant plasmid in the rat Olig2. DESIGN, TIME AND SETT...

Neurotrophin-3 (NT-3) can promote the repair of central nervous system and retinal damage. In previous reports, NT-3 has been expressed by viral vectors. However, plasmid vectors have a safer profile compared with viral vectors in clinical studies. This study recombined amplified human retinal NT-3 with a eukaryotic expression plasmid containing green fluorescent protein (GFP) to construct an N...

The efficacy of pEGFP (plasmid expressing enhanced green fluorescent protein)-encapsulated PEGylated (meaning polyethylene glycol coated) magnesium phosphate nanoparticles (referred to as MgPi-pEGFP nanoparticles) for the induction of immune responses was investigated in a mouse model. MgPi-pEGFP nanoparticles induced enhanced serum antibody and antigen-specific T-lymphocyte responses, as well ...

conclusions in conclusion, pegfp-kmp-gp96 (fusion) induced th1 platform immune response against leishmania major (mrho/ir/75/er) infection. results according to the results, the level of cytokines interferon-gamma (ifn-γ) and interleukin (il)-4, and ratio of ifn-γ /il4 was changed among different groups of mice before and seven weeks after immunization. the cytokines were increased significantl...

The pathogenic amoeba Naegleria fowleri has a 360-bp nfa1 gene that encodes the Nfa1 protein (13.1 kDa), which is located in the pseudopodia of the amoeba, and an anti-Nfa1 antibody reduces N. fowleri-induced mammalian-cell cytotoxicity in vitro. In contrast, an anti-Nfa1 antibody cannot detect Nfa1 protein expression in the nonpathogenic amoeba Naegleria gruberi, which also possesses the nfa1 ...

The constructs pEGFP BIN1 full length (isoform 8, 454 aa) and pEGFP BAR+PI (aa 1-281) were obtained from P. De Camilli (Yale University, New York). cDNA corresponding to MTM1 sequence (603 aa) was cloned into pEGFP-C1 (Clontech, N-ter GFP fusion) by PCR amplification followed by BamH1 restriction and into pCS2+ vector ([1], untagged). cDNA corresponding to the full length, BAR+PI, BAR (aa 1-255...

BACKGROUND The main barriers to non-viral gene delivery include cellular and nuclear membranes. As such, the aim of this study was to develop a type of vector that can target cells through receptor-mediated pathways and by using nuclear localization signal (NLS) to increase the nuclear uptake of genetic materials. METHODS A dexamethasone (Dexa)-conjugated lipid was synthesized as the material...

OBJECTIVE To study the effects of hepatitis C virus gene nonstructural protein 2 on the expressions of Bcl-2 and Bax in liver hepatocellular cells. METHOD The study was conducted at the Department of Infectious Diseases, the First Affiliated Hospital of Medical School, Xi'an Jiaotong University, Xi'an, China, from March 2012 to April 2013. Negative controls pEGFP-C3-NS2, pEGFP-C3-C and pEGFP-...
