A method system for modulating the energy expenditure and / or the expressed brain-derived neurotrophic factor (BDNF) in the brain of an individual is performed by a system that includes a control device that generates a stimulation pattern from a predetermined set of stimulation parameters, and that converts the stimulation pattern into a stimulation signal. A stimulation signal delivery mechanism, configured for implantation into a selected part of the brain, receives the stimulation signal from the control device and delivers the signal to the selected part of the brain. The stimulation signal may be an electrical signal delivered by a brain-implantable electrode, or a chemical signal in the form of a drug dosage regimen delivered by an implantable micropump under the control of the control device. Modulation of the energy expenditure and / or BDNF is achieved by the stimulation of the hypothalamus, either directly or indirectly, by the stimulation signal.

The present invention relates to the discovery of a novel molecular pathway involved in long-term hyperexcitability of sensory neurons, which, in higher animals, is associated with persistent pain. It is based on the discovery that, following injury to an axon of a neuron, an increase in nitric oxide synthase activity results in increased nitric oxide production, which, in turn, activates guanylyl cyclase, thereby increasing levels of cGMP. Increased cGMP results in activation of protein kinase G (“PKG”), which then is retrogradely transported along the axon to the neuron cell body, where it phosphorylates MAPKerk.

The present invention provides a method of enabling the use of long dsRNA for gene silencing in mammalian cells through bacteria, preferably non-pathogenic or therapeutic strains of bacteria. DNA that encodes long double-strand RNAs are transformed into bacteria and processed in the bacterial cells into a mixture of smaller RNA duplexes and then released into the cytoplasm of the target cells, resulting in modulation of gene expression in the target cells. The methods overcome the incompatibility between long strong dsRNA and mammalian cells by eliminating, or mitigating, the non-specific innate immune response. The eukaryotic cells can be mammalian cells or avian cells. The gene of interest can be a mammalian, avian, bacterial, eukaryotic, or viral gene.

These results identify tumor-induced osteolysis and bone resorption as potential targets of anti-IL-8 therapy.

The method of treating impaired wound healing in diabetics comprises the step of administering an effective amount of a glycogen synthase kinase 3-β (GSK-3β) inhibitor to a diabetic patient in need thereof to activate the NF-E2-related factor 2 (Nrf2) and genes downstream of Nrf2 that normally regulate the expression and coordination of antioxidant responses during wound healing, but are suppressed in the diabetic patient undergoing the oxidative stress that can occur during wound healing. The GSK-3β inhibitor may be lithium or a pharmaceutically acceptable salt thereof, or TDZD-8 (4-benzyl-2-methyl-1,2,4-thiadiazolidine-3,5-dione). The method may further comprise the step of testing the diabetic patient for the presence of oxidative stress and decreased Nrf2, which enables the early or prophylactic treatment of the patient with a GSK-3β inhibitor when the patient first presents with a wound, rather than waiting for other symptoms of impaired wound healing to occur.

Induced Pluripotent Stem Cell (iPSC) technology enables the generation and study of living brain tissue relevant to Parkinson's disease (PD) ex vivo. Utilizing cell lines from PD patients presents a powerful discovery system that links cellular phenotypes observed in vitro with real clinical data. Differentiating patient derived iPSCs towards a dopaminergic (DA) neural fate revealed that these cells exhibit molecular and functional properties of DA neurons in vitro that are observed to significantly degenerate in the substantia nigra of PD patients. Clinical symptoms that drive the generation of other relevant cell types may also yield novel PD specific phenotypes in vitro that have the potential to lead to new therapeutic avenues for patients with PD. Due to their early onset and nonfamilial origin, differentiated nervous tissue from these patients offer a key opportunity to discover neuron subtype specific pathological mechanisms and importantly interrogate the contribution of their genetic background in susceptibility to PD.
