Such methods include administering to the subject in a medically acceptable manner, a short oligopeptide such as AQGV (SEQ ID NO:1) and/or LQGV (SEQ ID NO:2). | 10-30-2008 |
20080306009 | Immunoregulatory compositions - The invention relates to compounds exhibiting immunoregulatory activity as determined by measuring the compound's ability to modulate production of NO by a cell. Preferred compounds include or consist of a sequence | 12-11-2008 |
20090042807 | Oligopeptide treatment of ischemia reperfusion injury - The invention relates to the modulation of gene expression in a cell, also called gene control, in particular, in relation to the treatment of ischemic-reperfusion injury. The invention provides a method for modulating expression of a gene in a cell comprising providing the cell with a signaling molecule comprising a peptide or functional analogue thereof. The invention provides a method of treating ischemia-reperfusion injury in a subject by reducing NO production by the subject's macrophages, the method comprising: administering to the subject a composition comprising: means for reducing production of NO by a cell, together with a pharmaceutically acceptable excipient. | 02-12-2009 |
20090227505 | Methods and uses for protein breakdown products - Where it was generally thought that the smallest breakdown products of proteins had no specific biological function on their own, it now emerges that the body may utilize the normal process of proteolytic breakdown to generate important compounds such as gene-regulatory compounds. For instance, certain short breakdown products of hCG (i.e., short peptides which can easily be synthesized, if needed modified, and used as a pharmaceutical composition) exert a major regulatory activity on pro- or anti-inflammatory cytokine cascades that are governed by a family of crucial transcription factors, the NF-κB family, which generally regulate the expression of genes involved in the body's immune response. | 09-10-2009 |
20090281033 | Control of radiation injury - The invention relates to the field of drug development against acute radiation injury caused by exposure to high-energy electromagnetic waves (X-rays, gamma rays) or particles (alpha particles, beta particles, neutrons). To date, there is no effective drug to ameliorate radiation injury after accidental exposure to ionizing irradiation. The invention provides a method of treating radiation injury of a subject in need thereof comprising administering to the subject a peptide, or functional analogue or derivative thereof, of smaller than 30 amino acids. Furthermore, the invention provides use of a peptide, or functional analogue or derivative thereof, of smaller than 30 amino acids for the production of a pharmaceutical composition for the treatment of a subject suffering from or believed to be suffering from radiation injury. In particular, the invention provides anti-radiation peptides having a dose reduction factor (DRF) against acute gamma irradiation of at least 1.10, said DRF determinable by testing which dose of radiation results in 50% mortality at 30 days (LD50/30) after whole body radiation (WBI) in a test group of mice treated with said peptide at 72 hours after WBI and, testing which dose of radiation results in 50% mortality at 30 days (LD50/30) after whole body radiation (WBI) in a control group of mice treated only with the vehicle of said peptide at 72 hours after WBI and wherein the DRF is calculated by dividing the LD50/30 of the peptide-treated animals by the LD50/30 of the vehicle-treated animals. | 11-12-2009 |
