Aim: To construct an HEK293 cell line stably expressing human dopamine D1 receptor (D1R). Methods: cDNA was amplified by RT-PCR using total RNA from human embryo brain tissue as the template. The PCR products were subcloned into the plasmid pcDNA3 and cloned into the plasmid pcDNA3.1. The cloned D1R cDNA was sequenced and stably expressed in HEK293 cells. Expression of D1R in HEK293 cells was m...

Background: Hepatitis C (HCV) is a worldwide problem without an effective vaccine with more than 170 million chronically infected people worldwide. DNA vaccines expressing antigenic portions of the virus with adjutants have recently been developed as a novel vaccination technology. Objectives: In the present study, a DNA vaccine expressing HCV core protein was developed with IL12 as a genetic a...

Abstract Introduction Calcific aortic valve stenosis (CAVS) is a clinically relevant issue due to the lack of drugs for prevention or treatment. CAVS driven by endothelial dysfunction and inflammation. A novel therapeutic strategy should target specific molecules involved in regulation both function immune responses. G protein-coupled receptor kinase 2 (GRK2) regulates desensitization downregul...

BACKGROUND Leishmania is a pathogenic parasite which infects mononuclear cells in vertebrate hosts. Different strategies have been taken to develop immunity against Leishmania. DCs loaded with immunogenic antigen have resulted in different levels of Th1-type immune response and cytotoxic T lymphocytes (CTL) activity. OBJECTIVE To evaluate the potency of DCs primed with soluble Leishmania mexi...

conclusions: e. coli herb-resistance plasmid can replicate and be expressed in s. aureus. results: the identified 45 kb herb-resistance plasmid could be transferred from e. coli cp9 isolates to e. coli dh5α. as a consequence e. coli dh5α transconjugant mic increased from 0.0125 g/ml to 0.25 g/ml. the plasmid was easily transferred from e. coli cp9 strain to s. aureus rn450rf with a mean transfe...

Huntingtin (Htt) mutation causes Huntington's disease. Sequence analysis of Htt revealed a possible thrombin cleavage site in the N-terminal region of Htt. In order to investigate if thrombin can cleave Htt, we expressed the N-terminal fragment (1-969) of wild-type (wt) Htt (Htt 1-969) in MCF-7 cells and studied its cleavage pattern by thrombin in vitro. An expression plasmid pcDNA3-Htt-18Q-969...

The thyroid sodium-iodide symporter (NIS) is responsible for iodide concentrating ability within thyroid follicular cells. We sought to develop monoclonal antibodies against human NIS (hNIS) for use as reagents in structure-function studies of the protein, as well as potential tools in the assessment of NIS expression in benign and malignant thyroid tissues. Synthetic peptides corresponding to ...

An antitumour lectin (named AAL) consisting of two identical subunits of 15.8 kDa was isolated from the fruiting bodies of the edible mushroom Agrocybe aegerita using a procedure which involved precipitating the extract by addition of (NH(4))(2)SO(4), ion exchange chromatography on DEAE-Sepharose Fast Flow, gel filtration chromatography on Sephacryl S-200 HR and finally purification on a GF-250...
