Methods and compositions are provided for protecting or enhancing excitable tissue function in mammals by systemic administration of an erythropoietin receptor activity modulator, such as erythropoietin, which signals via an EPO-activated receptor to modulate the function of excitable tissue. Excitable tissues include central neuronal tissues, such as the brain, peripheral neuronal tissues, retina, and heart tissue. Protection of excitable tissues provides treatment of hypoxia, seizure disorders, neurodegenerative diseases, hypoglycemia, and neurotoxin poisoning. Enhancement of function is useful in learning and memory. The invention is also directed to compositions and methods for facilitating the transport of molecules across endothelial cell tight junction barriers, such as the blood-brain barrier, by association of molecules with an erythropoietin receptor activity modulator, such as an erythropoietin.

Biodegradable neurotoxin implants and methods of making and using such implants are provided. Biodegradable neurotoxin implants include a neurotoxin, a biodegradable polymer component, and an acidity regulating component. The biodegradable polymer component is effective in controlling the release of the neurotoxin from the implant when the implant is located in a patient's body. The acidity regulating component is effective in maintaining a pH of the implant in a desired range that may be effective in stabilizing the neurotoxin as the implant biodegrades when the implant is located in a patient's body. In one embodiment, an implant includes a botulinum toxin, a biodegradable polymer, and either monomers from which a biodegradable polymer is derived or oligomers including monomeric units substantially identical to a monomer from which a biodegradable polymer is derived, or a combination of such monomers and oligomers. The oligomers and biodegradable polymer may be derived from a single type of monomer. The implants disclosed herein may be administered to a human or animal patient in which a therapeutic effect is desired for prolonged periods of time.

Methods for treating conditions in an animal or human subject. The conditions may be pain, skeletal muscle conditions, smooth muscle conditions, glandular conditions and cosmetic conditions.

The present invention discloses compositions and methods for enhancing the effect (e.g., duration) of a neurotoxin treatment. The compositions herein include neurotoxins and neuron growth inhibitors. Such compositions are administered locally to treat or prevent conditions, such as dermatological conditions, urological conditions, thyroid conditions, optical conditions, and neurological conditions.

A method of producing in a cell in vivo a clostridial neurotoxin light chain peptide by delivering into the cell in vivo a nucleic acid construct. The nucleic acid construct comprises (a) a nucleic acid encoding a clostridial neurotoxin light chain peptide and (b) a regulatory sequence operably linked to the nucleic acid to allow expression of the nucleic acid. The expression of the nucleic acid produces the clostridial neurotoxin light chain peptide in the cell in vivo.

The present invention discloses modified neurotoxins with altered biological persistence. In one embodiment, the modified neurotoxins are derived from Clostridial botulinum toxins. Such modified neurotoxins may be employed in treating various conditions, including but not limited to muscular disorders, hyperhidrosis, and pain.

To control cardiac arrhythmias, various conduction-modifying agents include biopolymers, fibroblasts, neurotoxins, and growth factors are introduced either epicardially or endocardially to the fat pads in proximity to the ganglia therein. Any desired technique may be used for injection, including injection from a catheter inserted percutaneously, or direct injection through the epicardial during open heart surgery. Preferably the patient's heart is beating throughout the Injection.

Botulinum toxin, among other presynaptic neurotoxins is used for the treatment and prevention of migraine and other headaches associated with vascular disorders. Presynaptic neurotoxins are delivered focally, targeting the nerve endings of the trigeminal nerve, the occipital nerve and the intranasal terminals of the parasympathetic fibers originating in the Sphenopalatine ganglion. The administration preferably targets the extracranial nerve endings of the trigeminal nerve in the temporal area, the extracranial occipital nerve endings in the occipital area, and the intranasal terminals of the trigeminal nerve and parasympathetic fibers originating in the Sphenopalatine ganglion. The delivery is carried out by way of injection or topically.

Provided are methods for protecting against or reducing neurotoxicity of exposure to a neurotoxic agent, comprising administering an electrokinetically altered aqueous fluid as provided herein in an amount sufficient to provide for neuroprotection against the neurotoxic agent, preferably where protecting against or reducing loss of motor coordination in the subject exposed to the neurotoxin is afforded. In certain aspects, protecting or reducing neurotoxin-mediated neuronal apoptosis is afforded, and / or activating or inducing at least one of PI-3 kinase and Akt phosphorylation in neurons is afforded. Preferably, administering the fluid comprises administering the fluid prior to exposure to the neurotoxic agent. Additionally provided are methods for preserving or improving motor coordination in a subject having a neurodegenerative condition or disease, comprising administering an electrokinetically altered aqueous fluid as provided herein in an amount sufficient to provide for preserving or improving motor coordination in the subject.

A molecular construct comprises a donor label, an acceptor label, a linker peptide disposed between the donor and the acceptor, the linker having a cleavage site sequence, and a spacer between at least one of (a) the donor and the cleavage site sequence and (b) the acceptor and the cleavage site sequence. Preferably, the construct is selected from the group consisting of CFP-(SGLRSRA)-SNAP-25-(SNS)-YFP, and CFP-(SGLRSRA)-synaptobrevin-(SNS)-YFP. In preferred embodiments, the linker peptide is a substrate of a botulinum neurotoxin selected from the group consisting of synaptobrevin (VAMP), syntaxin and SNAP-25, or a fragment thereof that can be recognized and cleaved by the botulinum neurotoxin. Advantageously, the spacer increases the electronic coupling between the donor label and the acceptor label relative to a corresponding construct without the spacer.

The present invention provides a method of treating a cancer using a neurotoxin, preferably Botulinum toxin (“BTX”). The application of a neurotoxin around a cancer acts to decrease the contractile forces of the muscles surrounding a neoplasm which normally squeeze cancer cells through efferent channels leaving the cancer vicinity to distant sites. Also, the application of the toxin at sites distant from the cancer enhances cellular and humoral immunologic functions which further contributes to cancer cell death and spread. Following administration of botulinum toxin around and distant to a cancer, it is noticed that local, regional, and distant spread is reduced or eliminated. Immunomodulation with botulinum toxin is also valuable in treating other disease that may or may not be associated with cancers, such as viral-induced growths, viral conditions, fungal disease, chronic wounds, graft versus host disease, autoimmune disease, and HIV.

The antibodies and derivatives thereof and / or other antibodies that specifically bind to the neutralizing epitopes provided herein can be used to neutralize botulinum neurotoxin and are therefore also useful in the treatment of botulism.
