The invention is directed to methods of promoting neurogenesis by contacting neuronal tissue with neurogenesis modulating agents. Novel methods for treating neurological disorders using neurogenesis modulating agents are disclosed.

The present invention describes methods involving the use of muscle derived cells (MDCs), preferably obtained from skeletal muscle, to support the innervation and repair of damaged tissues and organs, particularly associated with nerve damage or neuropathy. The invention relates to MDCs for use in methods for promoting or enhancing innervation of nerve cells, particularly in the peripheral nervous system, and their ability to contribute to the development of neuronal tissue when MDCs are introduced at or near a tissue or organ site in need of repair due to injury, damage, disease, or dysfunction. Such methods are useful for the treatment of central and peripheral nervous system disorders and to alleviate, abate, or eliminate the symptoms of neurologic or neurodegenerative diseases in animals, particularly mammals, including humans. The methods are also useful for treating both nerve and muscle tissue following injury, damage, or dysfunction to these tissue types.

Formulations and methods of use thereof for restoring neuronal tissue function in children and adults afflicted with chronic neurodegenerative diseases, such as neurodegenerative movement disorders and ataxias, seizure disorders, motor neuron diseases, and inflammatory demyelinating disorders. Examples of disorders include Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). The method involves administering a pharmaceutical composition containing an effective amount of a tetrahydrobenzathiazole, preferably a formulation consisting substantially of the R(+) enantiomer of pramipexole. R(+) pramipexole is generally administered in doses ranging from 0.1-300 mg/kg/daily, preferably 0.5-50 mg/kg/daily, and most preferably 1-10 mg/kg/daily for oral administration. Daily total doses administered orally are typically between 10 mg and 500 mg. Alternatively, R(+) pramipexole can be administered parenterally to humans with acute brain injury in single doses between 10 mg and 100 mg, and/or by continuous intravenous infusions between 10 mg/day and 500 mg/day.

Use of antagonists to IL-31 are used to treat inflammation and pain by inhibiting, preventing, reducing, minimizing, limiting or minimizing stimulation in neuronal tissues. Such antagonists include antibodies and fragments, derivative, or variants thereof. Symptoms such as pain, tingle, sensitization, tickle associated with neuropathies are ameliorated.

A catheter system and method for selectively cooling or freezing target neuronal tissue to induce lesions along the neuroaxis and produce cryoanalgesia by impairing nerve conduction of the targeted neuronal tissue. The system includes a catheter that has cryogenic capability for variable cooling or freezing of neuronal tissue. The catheter also includes temperature sensing and electrodiagnostic capabilities. A pressurized fluid source is included for inflating a portion of the catheter body. The system includes electrodiagnostic equipment for stimulating and monitoring sensory evoked potentials in the patient. The method involves placement of the catheter tip in the subarachnoid space of the spinal canal and location of the tip on the neuronal target using imaging and electrodiagnostic techniques.

The present invention provides a composition based on poly-1-lactic acid (PLLA) and polylactic-co-glycolic-acid (PLGA) scaffold on which neuronal tissue can ex-vivo grow. Further, more the invention provides a method for making cellular vasculature networks and a method for treating a neuronal injury in a subject, by implanting the current composition.

The present invention provides compositions and methods for alleviation or reduction of the symptoms and signs associated with damaged neuronal tissues whether resulting from tissue trauma, or from chronic or acute degenerative changes. In particular, some embodiments of the present invention provide one or more pharmaceutical compositions comprising as an active ingredient a BMP2A inhibitor further comprising a pharmaceutically acceptable diluent or carrier. An additional embodiment provides a method for reducing damage to the central nervous system in a patient who has suffered an injury to the central nervous system, comprising administering to the patient a pharmaceutical composition in a dosage sufficient to reduce the damage. Yet another embodiment provides of the use of a BMP2A inhibitor for the preparation of a medicament for promoting or enhancing recovery in a patient who has suffered an injury to the central nervous system. Preferable inhibitors according to some embodiments of the invention are siRNA molecules and neutralizing antibodies. An additional embodiment provides a method for identifying a chemical compound that modulates apoptosis. Further, a process for diagnosing a neurodegenerative disease or an ischemic event in a subject is provided. The preferred methods, materials, and examples that will now be described are illustrative only and are not intended to be limiting; materials and methods similar or equivalent to those described herein can be used in practice or testing of the invention. Other features and advantages of the invention will be apparent from the following detailed description, and from the claims.

Novel neuroprotectant compositions and methods are described. β-Lactamase inhibitors are used to prevent or reduce loss of neuronal cells and neuronal cell function in patients afflicted with or susceptible to disease states or conditions known to result in or cause neuronal tissue insult.

This invention relates to methods and devices for the detection and characterization of psychoactive compounds by analyzing alterations of network level physiological characteristics before and after the introduction of a candidate sample onto an in vitro neuronal tissue sample. The invention further provides a software package that enables an operator to deliver a timed electrical pulse to neuronal samples at a specific point in their spontaneous or induced oscillations. Such temporal stimulations trigger unexpected and useful network level physiological responses.

The present disclosure relates to liposomal delivery vehicles comprising magnetic particles and their use in modifying stem cells for delivery to target sites such as neuronal tissues.

This invention relates to neuronal tissue which is suitable to restore neuronal deficits following transplantation. To reduce immunological side effects and to increase the microbiological and genetic safety of the tissue we propose tissue that does not contain glial cells and is maintained in vitro for prolonged periods. The method to generate expandable determined neuronal progenitor cell cultures includes the following procedures: dissection of appropriate mammalian brain regions, isolation of progenitor cells, expansion of progenitor cells, selection and expansion of individual cells and priming.

A real-time detection technique and a real-time, adaptive, model-independent control technique for detecting and stabilizing pathological physiological rhythms, such as repolarization alternans, on the basis of the rate dependence of excitable tissue such as cardiac and neuronal tissue is presented. Unlike other control methods, which require a number of beats to locate the period-1 fixed point, the technique locates the period-1 fixed point almost instantaneously, rapidly eliminating any higher-period or aperiodic rhythms.

The invention relates to the use of a pharmaceutical composition containing nicotinamide (NAM) and/or pyruvate as a neuroprotective medicament or gene therapy in the treatment of neurodegenerative disorders, in particular axon degeneration of neuronal tissue in ocular-related neurodegeneration diseases including glaucoma.
