In this paper we investigate a new notion of bases in Hilbert spaces and similar to fusion frame theory we introduce fusion bases theory in Hilbert spaces. We also introduce a new denition of fusion dual sequence associated with a fusion basis and show that the operators of a fusion dual sequence are continuous projections. Next we dene the fusion biorthogonal sequence, Bessel fusion basis, Hil...

To prevent important infectious diseases such as tuberculosis, malaria and HIV, vaccines inducing greater T cell responses are required. In this study, we investigated whether fusion of the M. tuberculosis antigen 85A to recently described adjuvant IMX313, a hybrid avian C4bp oligomerization domain, could increase T cell responses in pre-clinical vaccine model species. In mice, the fused antige...

Certain domains of bacterial toxins have been shown to facilitate translocation from extracellular and vesicular compartments into the cytoplasm. This feature represents an opportunity to enhance class I presentation of exogenous antigen to CD8(+) T cells. We investigated this notion by creating a novel fusion of the translocation domain (domain II) of Pseudomonas aeruginosa exotoxin A (ETA(dII...

The multi-residue determination of organophosphorus pesticides (OPs) is an important task due to the wide application and high toxicity of OPs. However, there is no promising immunoassay to monitor the multi-residue of O,O-dimethyl OPs. In this study, a monoclonal antibody (mAb) against a generic hapten of O,O-dimethyl OPs (O,O-dimethyl O-(3-carboxyphenyl)phosphorothioate) was prepared. To deve...

Nonimmunogenic antigens can be efficiently rendered immunogenic by targeting them to antigen-presenting cells via differentially expressed chemokine receptors. For example, self-tumor or HIV antigens genetically fused with proinflammatory chemoattractants elicit potent immune responses and protective antitumor immunity in mice. Herein we demonstrate that the mechanism by which chemokine fusions...

A CD8(+) cytolytic T-lymphocyte (CTL) response to antigen-presenting cells generally requires intracellular delivery or synthesis of antigens in order to access the major histocompatibility complex (MHC) class I processing and presentation pathway. To test the ability of pertussis toxin (PT) to deliver peptides to the class I pathway for CTL recognition, we constructed fusions of CTL epitope pe...

Antibodies have been expressed inside cells in an attempt to ablate the function of oncogene products. To make intracellular antibodies more generally applicable and effective in cancer therapy, we have devised a method in which programmed cell death or apoptosis can be triggered by specific antibody-antigen interaction. When intracellular antibodies are linked to caspase 3, the "executioner" i...

Fusion protein technology represents the strategy to achieve rapid, efficient, and cost-effective proteinexpression. Epsilon and Beta toxins are the most potent Clostridial toxins and cause disease in animals.This study describes in silico fusion of Clostridium perfringens types D and B epsilon and beta toxin genesthat was used for cloning in E.coli. The etx and cpb genes were...

Heating to 45 C induced in virus-free clones of simian virus 40 (SV40) transformed BSC(1) cells the synthesis of SV40 viral antigen, as evidenced by immunofluorescence. Up to 3.8% of the cells exhibited viral antigen 72 hr after heating to 45 C for 30 min. Depletion of arginine from the medium of the heated cells enhanced and increased the percentage of cells synthesizing viral antigen to 11%. ...

A human IgMk monoclonal antibody, 2F7, of predetermined specificity, has been produced by the fusion of human peripheral blood lymphocytes with the nonsecreting mouse myeloma line SP-1. The heterohybridoma has remained stable for over 8 mo, with culture supernatants containing up to 30 micrograms/ml of specific IgM. The antibody has been shown to be capable of inducing a blastogenic response in...
