Abstract:
The present invention relates to a chimeric protein comprising the CHAP catalytic domain of the endolysin LysRODI from phage PhiIPLA-RODI and the SH3b cell wall binding domain of the endolysin LysH5 from phage phiIPLA88. This chimeric protein shows an improved lytic activity again Staphylococcus sp. and a higher stability than the other endolysins of the state of the art. The invention also relates to a polynucleotide encoding the chimeric protein, and the host cell or the composition comprising the chimeric protein or the polynucleotide encoding thereof, as well as its use for the treatmentand/or preventionof an infection of Staphylococcus sp, and/or for removing, inhibiting and/or preventing Staphylococcus sp. biofilm formation on abiotic surfaces, or for removing and/or preventing the Staphylococcus sp. contamination of foods and/or abiotic surfaces.
Abstract:
Some aspects of this disclosure provide strategies, systems, reagents, methods, and kits that are useful for the targeted editing of nucleic acids, including editing a single site within the genome of a cell or subject, e.g., within the human genome. In some embodiments, fusion proteins of Cas9 and nucleic acid editing proteins or protein domains, e.g., deaminase domains, are provided. In some embodiments, methods for targeted nucleic acid editing are provided. In some embodiments, reagents and kits for the generation of targeted nucleic acid editing proteins, e.g., fusion proteins of Cas9 and nucleic acid editing proteins or domains, are provided.
Abstract:
The present invention provides protease-cleavage resistant molecules comprising Shiga toxin effector polypeptides capable of exhibiting potent, Shiga toxin functions ( e.g . subcellular routing and cytotoxicity). The present invention also provides protease-cleavage resistant, cell-targeted molecules for targeting specific cell types, e.g ., infected or malignant cells. Certain molecules of present invention are cytotoxic, and certain cell-targeted molecules of present invention may be used for the targeted killing of specific cell types and treatment of a variety of diseases, disorders, and conditions, including cancers, tumors, growth abnormalities, immune disorders, and microbial infections. Certain cell-targeted molecules of the invention exhibit improved, in vivo tolerability as compared to related cell-targeted molecules comprising protease-cleavage sensitive, wild-type, Shiga toxin effector polypeptides. The cell-targeted molecules of the invention can deliver additional materials, such as, e.g ., antigens, cytotoxic agents, and detection-promoting agents, into interiors of target cells.
Abstract:
Use of fusion protein comprising at least one polypeptide B, comprising Type 1 Ribosome Inactivating Protein, and at least one C having anticancer properties in the manufacture of a medicament for treating cancer in a subject in need thereof.
Abstract:
Provided herein are deglycosylating enzymes that remove a broad range of N-glycans from N-glycosylated proteins. Further provided are methods of recombinantly producing and expressing the deglycosylating enzymes. The presently described deglycosylating enzymes can be used to produce free glycans for characterization, and for prebiotic and immunostimulatory uses. In addition, the presently described deglycosylating enzymes can be used to produce deglycosylated proteins for characterization, to improve digestion, and to reduce immunogenicity.
Abstract:
The present disclosure describes nucleic acids, and viruses comprising such nucleic acids, for growing a toxic gene in an insect cell. These nucleic acids comprise a sequence encoding a toxic polypeptide, and an intron that interrupts the sequence, whereby the intron is spliced in mammalian cells but not in insect cells. Infection of mammalian cells but not insect cells with the nucleic acids or viruses can lead to expression of toxic levels of the toxic polypeptide in mammalian cells but not in insect cells. Viruses, such as an AAV or a baculovirus comprising a nucleic acid can be grown in insect cell lines in vitro and can be administered to a subject in need of therapy, such as a subject in need of cancer therapy.
Abstract:
The invention provides compositions and methods for delivering a bioactive moiety comprising at least one non-natural component into a cell cytosol of an eukaryotic cell. The bioactive moiety is linked to an A component of a bacterial toxin, a functional wild-type or modified fragment thereof, or an A component surrogate or mimetic. For delivery, the cell is contacted with the linked bioactive moiety and a corresponding B component of the bacterial toxin or a functional fragment thereof.
Abstract:
The present innovation relates to the identification of the main sequences of the protein nucleoside hydrolase from Leishmania (L) donovani, to be included in a recombinant, DNA or synthetic vaccine to protect and cross-protect against leishmanioses. It also relates to the identification of the main epitopes that react with antibodies to be used in the immunodiagnosis of leishmanioses, and to the use thereof to give cross-protection against other micro-organisms having a sequence in common in the nucleoside hydrolases thereof.
Abstract:
The present invention relates to the use of toxoids prepared using a-dicarbonyl toxoiding reagents such as glyoxal, butanedione and phenylglyoxal. The toxoids may be prepared with low concentrations of toxoiding reagent and in short periods of time, often in as few as 24 hours, making the toxoiding reagents particularly advantageous when compared with traditional formaldehyde toxoiding. Toxoids prepared using dicarbonyl reagents such as phenylglyoxal are described and claimed as are pharmaceutical and vaccine compositions comprising the toxoids, methods of treatment using such compositions and antibodies generated by immunisation with the toxoid and methods of treatment using the antibodies so prepared or fragments of such antibodies.
Abstract:
Provided herein, in one aspect, are antibodies that immunospecifically bind to a human KIT antigen comprising the fourth and/or fifth extracellular Ig-like domains (that is, D4 and/or D5 domains), polynucleotides comprising nucleotide sequences encoding such antibodies, and expression vectors and host cells for producing such antibodies. The antibodies can inhibit KIT activity, such as ligand-induced receptor phosphorylation. Also provided herein are kits and pharmaceutical compositions comprising antibodies that specifically bind to a KIT antigen, as well as methods of treating or managing a KIT-mediated disorder or disease and methods of diagnosing a KIT-mediated disorder or disease using the antibodies described herein.
