Application of TARP luciferase reporter system in function identification of CAR-T cells / 细胞与分子免疫学杂志

Objective To investigate a convenient and quantitative solution to activation levels and functional characterization of CAR-T cells by inserting T cell activity-responsive promoter (TARP) nanoluciferase reporter gene system into a lentiviral plasmid containing the gene encoding the chimeric antigen receptor (CAR). Methods The recombinant plasmid was constructed by using whole gene synthesis and molecular cloning techniques. The lentivirus was packaged and was infected with human primary T lymphocytes. Flow cytometry was used to detected the positive rate of lentivirus-infected T cells. The functional characterization of CAR-T cells was identified by luciferase reporter gene system, Western blot, flow cytometry, and small animal live imaging techniques. Results The results of enzyme digestion identification and the plasmid sequencing showed that the recombinant plasmids were constructed, and flow cytometry displayed the normal preparation of CAR-T cells. This system could dynamically respond to the activation of CAR-T cells by luciferase reporter gene system. The functional assay in vitro confirmed that the system could reflect the exhaustion of CAR-T cells, and the small animal live imaging results demonstrated that the system can be used as a tracer of CAR-T cells in mice. Conclusion TARP nanoluciferase reporter gene system provides a more convenient, sensitive and quantitative method for evaluating CAR-T cells activation level, exhaustion phenotype and tracing.

Analysis of immobilized L-glutamate oxidase fused with cellulose binding domain on microcrystalline cellulose / 生物工程学报

Immobilization of enzymes is important and widely applied in biocatalysis. Streptomyces platensis gene gox, encoding an extracellular L-glutamate oxidase (Gox), was fused to cellulose binding domain (CBDcex) from Cellulomonas fimi and the recombinant protein Gox-CBD was expressed in Escherichia coli. The fusion protein (Gox-CBD) was immobilized onto microcrystalline cellulose. The preparation conditions, binding capacity, properties and stability of the immobilized enzyme were studied. Under the condition of 4 ℃, for 1 hour, the fusion protein Gox-CBD was able to bind microcrystalline cellulose at a ratio of 9.0 mg of protein per gram of microcrystalline cellulose. Enzymatic properties of free and immobilized L-glutamic oxidase (Gox-CBD) were compared. The specific activity of the immobilized enzyme decreased, but its thermal stability increased a lot compared with that of the free Gox-CBD. After incubation at 60 ℃ for 30 min, 70% of the total activity remained whereas the free recombinant Gox completely lost its activity. The immobilized protein was tightly bound to microcrystalline cellulose at pH below 10 or more than 5 mmol/L NaCl. The fusion protein of Gox-CBD can be specifically immobilized on the microcrystalline cellulose on a single step. Therefore, our findings can provide a novel strategy for protein purification and enzyme immobilization.

A novel reporter system monitoring sortase A catalyzed protein ligation efficiency / 生物工程学报

Efforts on directed evolution of sortase A to optimize its catalytic properties have been undertaken and shown the promise. To facilitate screening of sortase A mutants with expected catalytic properties, a novel ligation efficiency monitoring system, including reporter substrates GFP-LPETG and GGGYK-Biotin, was developed. GFP-LPETG, wild type sortase A, and a recently reported high activity sortase A mutant were prepared recombinantly from Escherichia coli BL21 (DE3). Taking advantage of the newly designed reporter system, the ligation efficiency catalyzed by wild type and mutant form of sortase A could be sensitively monitored via SDS-PAGE directly. Consistent with previous report, the mutant sortase A displayed much higher catalytic activity compared to wild type enzyme, indicating the new reporter system is easily and fast handled and sensitive. The application of this reporter system into systemic screening will facilitate future directed optimization of sortase A.
