摘要:
The present invention is directed to the cells, compositions and methods for the production of recombinant protein, wherein an f-met group on the 5′-terminus is enzymatically removed. In particular, the invention is directed to a production process for obtaining high levels of soluble recombinant CRM197 protein from E. coli. Cells preferably contain one or more mutations of disulfide reductase genes, so that disulfide reductase activity is reduced. The invention also relates to purification method for CRM197 as well as characterization of properly folded CRM197 protein.
摘要:
Bordetella pertussis iron receptor proteins or portions thereof (e.g., one or more extracellular domains), alone or spliced into B. pertussis scaffold proteins (e.g., fimbrial or flagellin), are provided and can be used in acellular vaccines to protect against pertussis or other Bordetella diseases in humans and non-human mammals. In addition, Bordetella species grown under iron-starved conditions are provided and can be used in whole cell vaccines to protect against pertussis or other Bordetella diseases in humans and non-human mammals.
摘要:
A massive clonal expansion of activated CD8+ T-cells with increased frequency of HPV 16-specific CD8+ T-cells was discovered to be a characteristic of oral lichen planus (OLP), indicating a causal link between HPV infection and the dysimmune process. The invention relates to compositions and methods for the diagnosis and treatment of OLP patients.
摘要:
A process for fermenting Bordetella species comprising incubating a sample of bacteria of a Bordetella species in a first environment under at least one bvg (Bordetella virulence genes) modulating condition, for at least 5 generations, to produce a mature culture, and then incubating the mature culture in a second environment in the absence of the at least one bvg modulating condition.
摘要:
The invention relates to a novel use of a Bordetella adenylcyclase toxin in the manufacturing of vectors for targeting in vivo a molecule of interest, specifically to CD11b expressing cells. The invention also relates to an immunogenic composition that primes immune responses, to pharmaceutical compositions and to a new vector for molecule delivery to CD11b expressing cells.
摘要:
The present invention discloses methods and materials for delivering a cargo compound into a cancer cell. Delivery of the cargo compound is accomplished by the use of protein transduction domains derived from cupredoxins. The invention further discloses methods for treating cancer and diagnosing cancer.

摘要:
The invention relates to a recombinant protein comprising one or several polypeptides bearing one or several epitopes of one or several HPV antigens, said polypeptides being inserted in the same or different permissive sites of an adenylate cyclase (CyaA) protein or of a fragment thereof, wherein said CyaA fragment retains the property of said adenylate cyclase protein to target Antigen Presenting Cells. It also concerns polynucleotides encoding the same. The recombinant protein or the polynucleotide can be used for the design of therapeutic means against HPV infection or against its malignant effects.
