Methods, compositions and kits are provided for treating a subject exposed to or at risk for exposure to a disease agent, methods, compositions and kits having a pharmaceutical composition including at least one recombinant binding protein or a source of expression of the binding protein, wherein the binding protein neutralizes at least one or a plurality of disease agents that are toxins, for example at least one of a Botulinum toxin or an Anthrax toxin.

The invention relates to liposomes, methods of producing liposomes, and methods of loading cell-derived liposomes with cargo molecules. The invention extends to such liposomes per se, and to the use of these liposomes as cellular delivery systems for the delivery of biologically and therapeutically active payload molecules, such as small molecules, RNAi molecules (e.g. siRNA), bioactive proteins, genome editing tools (e.g. Cas9) and drugs into cells for treating a range of disorders. The liposomes may also be used in a range of diagnostic and theranostic applications. The invention extends to pharmaceutical compositions comprising such liposomes, including populations of extracellular vesicles (EV), exosomes and to fusion proteins.

Methods, compositions and kits are provided for treating a subject exposed to or at risk for exposure to a disease agent, methods, compositions and kits having a pharmaceutical composition including at least one recombinant binding protein or a source of expression of the binding protein, wherein the binding protein neutralizes at least one or a plurality of disease agents that are toxins, for example at least one of a Botulinum toxin or an Anthrax toxin.

Disclosed herein is a peptide substrate that is cleaved specifically by anthrax lethal factor (LF), and assays for detecting the presence of anthrax lethal factor in a sample using the peptide substrate. In some cases, the sample may be obtained from an individual at an early stage of an anthrax infection. Kits that include the peptide substrate and that find use in carrying out the assays are also disclosed.

Disclosed is a protein comprising a cytolethal distending toxin subunit B (CdtB) conjugated or fused to a Bacillus anthracis toxin lethal factor (LF) or a functional portion of LF. Related chimeric molecules, as well as related nucleic acids, recombinant expression vectors, host cells, populations of cells, pharmaceutical compositions, methods of treating or preventing cancer, and methods of inhibiting the growth of a target cell are also disclosed.

Provided herein are methods of integrating one or more exogenous nucleic acids into one or more selected target sites of a host cell genome. In certain embodiments, the methods comprise contacting the host cell genome with one or more nucleic acid constructs fused with a pore-forming toxin, which may further be targeted to a particular cell type, wherein the nucleic acid constructs comprise an exogenous nucleic acid to be integrated into a genomic target site, and an enzyme, such as a nuclease or recombinase or a combination thereof capable of targeted introduction of the nucleic acid into the genome.
