The invention generally relates to collagen-binding agent compositions and methods of using the same. More specifically, the invention relates in part to new collagen-binding agent compositions and methods that may be used to treat damaged collagen within tissues or used to specifically target therapeutics to tissues containing undamaged or damaged collagen.

Described herein are recombinant Clostridium botulinum neurotoxins comprising a light chain of a Clostridium botulinum neurotoxin, wherein the light chain comprises a mutation that causes minimal structural interference to the light chain protease; a heavy chain of a Clostridium botulinum neurotoxin, wherein the light and heavy chains are linked by a disulfide bond. The recombinant Clostridium botulinum neurotoxin has a 2-20 fold reduced toxicity compared to wild type Clostridium botulinum neurotoxin. Also described is a treatment method.

The present invention relates to new species-selective phage endolysins and their use to treat bacterial vaginosis (BV). The present invention provides recombinant endolysins, i.e. domain-swapped endolysins. The invention also relates to said endolysins for use in treating diseases or disorders such as bacterial infections, in particular BV. The invention further relates to polynucleotides encoding said endolysins. Said polynucleotides can also be used for treating such diseases or disorders. Also provided by the present invention is a pharmaceutical composition comprising an endolysin of the invention for use in treating such diseases or disorders. Said endolysins, polynucleotides and pharmaceutical composition may be administered locally, in particular locally into the vagina.

Enhanced, specific nucleic acid targeting complexes comprising endo and exonuclease activity, and related methods that allow both targeted degradation of specific and/or non-specific nucleic acids in vivo and specific temporal regulation of nuclease activity to prevent off-target activity are disclosed herein. Through practice of the disclosure, nucleic acids, and cells harboring them, such as cancer cells or pathogens, are selectively degraded in vivo.
