Abstract:
Disclosed herein are bacteriophage compositions and therapeutic uses thereof. The disclosure also relates to bacteriophage that are capable of lysing Klebsiella bacterial strains, e.g., strains that are associated with inflammatory bowel disease, and thereby capable of modulating disease.
Abstract:
Isolated polynucleotides encoding a BREX system are provided. Accordingly there is provided an isolated polynucleotide encoding a BREX system comprising a nucleic acid sequence encoding the BREX system comprising brxC/pglY, pglZ and at least one of pglX, pglXI, brxP, brxHI, brxHH, brxL, brxD, brxA, brxB, brxF , and brxE , with the proviso that said BREX system does not comprise pglW , and wherein said BREX system confers phage resistance to a bacteria recombinantiy expressing same; Also provided is an isolated polynucleotide encoding a BREX system comprising a nucleic acid sequence encoding the BREX system comprising brxC/pglY, pglZ, pglX, pglW and at least one of brxD and brxHI , and wherein said BREX system confers phage resistance to a bacteria recombinantiy expressing same. Also provided are compositions and methods for conferring phage resistance to bacteria or for conferring bacterial susceptibility to phages.
Abstract:
Bacteriophage compositions and therapeutic uses thereof. In particular, compositions of lytic bacteriophages that are capable of lysing Propionibacterium acnes ( P. acnes ) bacterial strains associated with acne and biofilms, thereby treating or preventing acne and biofilms.
Abstract:
Disclosed herein are microbial defense systems, which provide cells protection against phage infection and plasmid transformation. Methods of use of these defense systems for protecting cells from phage infection and plasmid transformation are also disclosed, wherein defense systems may be used individually or in combination. In addition, disclosed herein are methods of making cells that express these defense systems.
Abstract:
Methods of expressing an expression product of interest are provided. Accordingly there is provided a method comprising introducing into a cell a polynucleotide comprising an Aim R responsive element operatively linked to a nucleic acid sequence encoding the expression product of interest, and contacting said cell with an Aim P peptide comprising an amino acid sequence of XXXXGG/A, wherein said Aim P peptide is capable of binding said Aim R polypeptide and dissociating said Aim R polypeptide from said Aim R responsive element. Also provided are articles of manufacture, isolated peptides, polynucleotides and nucleic acid constructs.
Abstract:
An isolated polynucleotide is disclosed. The polynucleotide comprises a clustered, regularly interspaced short palindromic repeat (CRISPR) array nucleic acid sequence wherein at least one spacer of the CRISPR is sufficiently complementary to a portion of at least one prokaryotic gene so as to down-regulate expression of the prokaryotic gene and further comprises a nucleic acid sequence encoding at least one CRISPR associated (CAS) polypeptide of a repeat associated mysterious protein (RAMP) family. Uses of the polynucleotides and pharmaceutical compositions comprising the polynucleotides are also disclosed.
Abstract:
Disclosed herein are prokaryotic homologs of viperin (pVips), and nucleotide and nucleoside analogs produced from pVips. These nucleotide and nucleoside analogs stop nucleotide chain synthesis and provide host cells with resistance to viral infections by targeting actively replicating viral genome. Further, these nucleotide and nucleoside analogs decrease DNA replication in malignant cells. Further disclosed are methods of identifying pVips, and nucleotide and nucleoside analogs produced thereof.
