Patent number: 7879791Abstract: A mechanism of macrophage-induced T cell suppression is the selective elimination of tryptophan and/or increase in one or more tryptophan metabolites within the local macrophage microenvironment. Studies demonstrate that expression of IDO can serve as a marker of suppression of T cell activation, and may play a significant role in allogeneic pregnancy and therefore other types of transplantation, and that inhibitors of IDO can be used to activate T cells and therefore enhance T cell activation when the T cells are suppressed by pregnancy, malignancy or a virus such as HIV. Inhibiting tryptophan degradation (and thereby increasing tryptophan concentration while decreasing tryptophan metabolite concentration), or supplementing tryptophan concentration, can therefore be used in addition to, or in place of, inhibitors of IDO.Type: GrantFiled: November 21, 2006Date of Patent: February 1, 2011Assignee: Medical College of Georgia Research Institute, Inc.Inventors: David Munn, Andrew Mellor

Patent number: 6949658Abstract: The present invention provides a process for efficiently producing an optically active ?-amino acid and an optically active ?-amino acid amide. After contacting with cells or processed cells thereof having an ability to asymmetrically hydrolyse, a water solvent is substituted with at least one solvent selected from the group consisting of linear, branched, or cyclic alcohol having 3 or more carbon atoms and the optically active ?-amino acid is preferentially precipitated from the alcohol solution. The addition of basic compounds, particularly potassium compounds to the alcohol solution containing the optically active ?-amino acid amide, which is obtained after the separation of the optically active ?-amino acid, enables the purification of the amide without the inclusion of amino acid into amino acid amide. Thus, the amide is subjected to the step of racemization and then recycled.Type: GrantFiled: May 18, 2001Date of Patent: September 27, 2005Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Osamu Katoh, Toshitaka Uragaki, Tetsuji Nakamura

Patent number: 6423738Abstract: A method for treating circadian rhythm phase disorders is described. The invention provides methods to specifically advance or delay the phase of certain circadian rhythms in humans. The disclosed methods relate to the administration of melatonin at times determined with relation to the time of dim light endogenous melatonin onset. Embodiments capable of alleviating the effects of jet lag, winter depression and shift-work sleep disturbance are provided.Type: GrantFiled: May 30, 2000Date of Patent: July 23, 2002Assignee: Oregon Health & Sciences UniversityInventors: Alfred J. Lewy, Robert L. Sack
