Inflammation Induction and Tissue Repair
- 技术应用
- The non-coding U1 snRNA potentially can be used to induce tissue necrosis in certain types of cancers and may have therapeutic applications in infectious diseases. Conversely, anti RNAs could be synthesized to block the inflammatory effects of U1 snRNA, or TLR3 antagonists could be used to attenuate inflammation from some forms of tissue necrosis injury such as radiation.
- 详细技术说明
- UCSD researchers have found that non-coding U1 small nuclear RNAs (snRNA) play an important role in the inflammation process. In an irradiated mouse model, endogenous non-coding U1 snRNA becomes altered and is recognized by the Toll-like Receptor 3 (TLR3). Together with TLR3, U1 RNA can then induce the NF-kappa B inflammatory cascade. The induction can be replicated by injecting the mice with radiated U1 RNA. The role of TLR3 is essential since the U1 RNA-mediated induction of inflammation does not occur in mice lacking TLR3 expression. Furthermore, the newly generated fractions from the radiated U1 RNA that are less than 100 nucleotides are potent stimuli of TNF-alpha.
- *Abstract
-
Inflammation is an important response for resisting infection and repairing damage. Under circumstances such as cancer or infectious diseases, stimulation of the inflammatory response is therapeutic. It is unclear why the existing adjuvant therapies tend to be more effective in the treatment of some disease, such as breast and colon cancer, than others. This invention identifies additional ways to stimulate the immune response and induce inflammation in order to accelerate repair of disease-related tissue injury.

Summary: For treating an infection in a subject, where the infection is a skin infection including skin wound; for identifying an agonist or antagonist of inflammation which is used treating an inflammatory disease or disorder selected from acne, rosacea, atopic dermatitis, contact dermatitis, drug eruptions, psoriasis, seborrheic dermatitis, lupus, scleroderma, rheumatoid arthritis, blistering disease, bullous pemphigoid or pemphigus, inflammatory hyperpigmentation, melasma and vitiligo, and urticaria or hives (claimed). Also used in treating pneumonia, meningitis, osteomyelitis, endocarditis, sinusitis, urinary tract infections, tetanus, gangrene, colitis, acute gastroenteritis, and impetigo.
Novelty: Composition used in treating e.g. skin infection, acne, rosacea, dermatitis, psoriasis, seborrheic dermatitis, lupus, scleroderma, rheumatoid arthritis comprises isolated photo fragmented small nuclear ribonucleic acid oligonucleotides
