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.

Compositions comprising activatable recombinant neurotoxins and polypeptides derived therefrom. The invention also comprises nucleic acids encoding such polypeptides, and methods of making such polypeptides and nucleic acids.

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.

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 sphenopalatine ganglion. Exemplary delivery is carried out by way of injection.

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.

Antibodies for binding epitopes of BoNT/A and hybridomas which produce such antibodies are described. The antibodies of the present invention can be used in a method for detecting BoNT/A in a sample and/or in a method for purifying BoNT/A from an impure solution. In addition, the antibodies can be used for passive immunization against BoNT/A intoxication or as intoxication therapy. Another aspect of the invention is a kit for detecting BoNT/A in a sample.

The present invention relates to methods for treating neurological-urological conditions. This is accomplished by administration of at least one neurotoxin.

The invention provides methods for treating primary disorders of mood and affect, including depressive disorders, anxiety and sleep disorders and CNS disorders comprising the administration of a neurotoxin.

The present invention discloses compositions and methods for the prevention and treatment of skin and hair diseases, such as, for example, alopecia, psoriasis, and keloids. The present invention also relates to compositions and methods for altering skin coloration. The present invention also relates to methods for enhancing the effect of a neurotoxin.

The disclosure provides compositions relating to thermostable vaccines and methods of preparing same. Specifically, the disclosure provides for methods of preparing thermostable vaccines based on a recombinant ricin neurotoxin protein and uses of co-adjuvants to develop a composition capable of eliciting an immune response in a subject.
