Patent CA-2402530-A1 (CA)
Inventor: SCHENKEL ALAN R
IPC: C07K16/28
Filed: 2001-03-13
Abstract: The present invention provides methods and compositions for modulating transendothelial migration (TEM) of leukocytes. In particular, inhibition of TEM can provide a potent therapeutic approach to treating inflammatory conditions. The invention specifically relates to the discovery that CD99 mediates TEM, because blocking CD99 on either endothelial cells or monocytes bloks migration 80-90 %. In conjunction with PECAM inhibitors, TEM blockade approaches 100 %. CD99 is involved in a step in TEM that is distal to the step controlled by PECAM.

Filed: 2001-10-10
Abstract: Selon l'invention, les profils de coordination d'actions font partie d'une plate-forme de technologie de traitement de données différente mais souvent complémentaire à la méthode statistique. Ces profils reposent sur l'utilisation de mesures répétées ou de données de séries chronologiques pour mesurer les interactions (associations longitudinales, contingences temporelles) entre et parmi plusieurs variables ou séries de variables relatives à des éléments individuels. Ces mesures d'interaction montrent comment des systèmes complexes d'éléments individuels peuvent être commandés et régulés, comment deux ou plusieurs systèmes d'éléments individuels peuvent interagir, comment des systèmes complexes peuvent être commandés ou affectés par leurs environnements, y compris leurs traitements, et comment des systèmes individuels peuvent commander ou affecter leurs environnements. Ces systèmes peuvent faire l'objet de recherches sur le cerveau, les organismes, les patients, les économies, les marchés des fonds d'investissement, les populations, les machines, ou les procédés. Ces actions peuvent être physiques, chimiques, biologiques, comportementales, mentales ou sociales. Cette invention peut être utilisée comme aide à l'obtention d'informations dans la création de modèles mathématiques. Cette invention peut également être utilisée comme aide à l'expression de données par obtention de conclusions générales et de prédictions relatives à la façon dont des éléments individuels fonctionnement et interagissent avec leur environnement. Ces profils de coordination des actions et les modèles résultants peuvent aider à faire avancer les sciences fondamentales et appliquées.

Abstract: Drugs and foods processed so as to effectively exert physiological activities, in case of orally administering physiologically active protein(s).  Compositions for oral administration which contain one or more physiologically active proteins as the active ingredient and provided with a release-controlling means. Use of these compositions makes it possible to deliver at least 10% of the active ingredient to the lower digestive tract while sustaining the physiological activities. Since the physiologically active proteins are not digested in the stomach but delivered to the small intestine, it becomes possible to exert an effect which has been unknown so far or to ensure the achievement of an effect. Preferable examples of the physiologically active proteins contained in these compositions include lactoferrin, immunoglobulin, lysozyme, amylase, protease, lipase and digestive enzyme inhibitors.
