The present invention provides methods of treating allergic disorders and compositions for use therein. The methods comprise administering an allergen and one or more medicaments. These medicaments are compounds that inhibit the transcription of genes involved in the initiation of innate and specific immunity, thereby promoting the development of tolerance to these allergens, through inhibition of the NF-κB and/or the MAPK/AP-1 signal transduction pathway(s). In another embodiment, the use of DNA vaccines is disclosed that incorporate a gene encoding one or more allergen sequences or fragments thereof, in combination with genes encoding proteins that inhibit the activation of the NF-κB and/or the MAPK/AP-1 pathway or in combination with small interfering RNA sequences or anti-sense sequences that inhibit the expression of NF-κB and/or AP-1 proteins.
The present invention is directed to systems and methods for contributing to the local treatment of pain. More specifically, the present invention is directed to the use of one or more NFKB inhibiting compounds, particularly clonidine, in the manufacture of a medicament for the treatment of pain wherein said medicament is for local administration to a patient in need thereof.
Composition containing iridoids such as morroniside and loganin, the use thereof in preparing medicaments for preventing and treating neurologic demyelinating diseases, and the method thereof in treating diseases related to neurologic demyelinating lesions are disclosed by the present application.
