Abstract: An oligonucleotide is provided. The oligonucleotide comprising a nucleic acid sequence of at least one DNAzyme, the DNAzyme being capable of silencing at least one target gene of a bacteria to thereby render the bacteria susceptible to antibiotic treatment.

Abstract: Provided herein are DNAzymes conjugated to an organic moiety and methods of facilitating entry of DNAzymes into bacteria, utilizing same. Also provided are methods of targeting bacterial target genes, methods of treating or inhibiting the progression of bacterial infections, and methods of increasing susceptibility of bacteria to an antibiotic, using the described DNAzymes, which are optionally capable of silencing at least one target gene of bacteria and/or rendering bacteria susceptible to antibiotic treatment.

Abstract: Disclosed are recombinant multiple epitope polypeptides (MEPs) consisting of T cell epitopes derived from tumor-associated antigens capable of being presented by an antigen presenting cell (APC), the recombinant nucleic acid sequences and expression vectors encoding them, and host cells transfected with said expression vectors. Further described are LTB-MEP fusion proteins comprising the E. Coli heat labile enterotoxin subunit B (LTB) peptide fused to a MEP by a synthetic linker, the recombinant nucleic acid sequences and expression vectors encoding them and host cell transfected with said expression vectors. Further included are compositions for inducing an immune response against malignancies, pharmaceutical compositions and a transdermal drug delivery system for the treatment of malignant disorders. Also disclosed are methods for conferring immunity against malignancies and for the treatment of malignant disorders.
