Abstract: Il est possible de déjouer la tolérance du système immun à l'égard d'antigènes de différenciation autonome et de stimuler une réponse immune par administration d'un antigène de différenciation thérapeutique. On a modifié de trois manières cet antigène de différenciation thérapeutique par rapport à l'antigène de différenciation cible, chez l'individu en cours de traitement (à savoir l'antigène de différenciation vis-à-vis duquel une réponse immune est souhaitée). Premièrement, l'antigène de différenciation thérapeutique peut être syngénique avec l'antigène de différenciation cible, à condition que l'antigène de différenciation thérapeutique soit exprimé dans des cellules d'une espèce différente de celle appartenant à l'individu en cours de traitement. Par exemple, on peut utiliser un antigène de différenciation humain exprimé dans un insecte ou dans tout autre cellule hôte non humaine, afin de stimuler, chez l'homme, une réponse immune à l'égard de l'antigène de différenciation. Deuxièmement, l'antigène de différenciation thérapeutique peut être une forme mutante d'un antigène de différenciation syngénique, par exemple un mutant par glycosylation. Troisièmement, l'antigène de différenciation thérapeutique peut être un antigène de différenciation (de type sauvage ou mutant) du même type mais provenant d'une espèce différant de celle de l'individu en cours de traitement. Par exemple, on peut utiliser un antigène de différenciation de souris pour stimuler chez l'homme une réponse immune à l'égard de l'antigène de différenciation correspondant. L'administration d'antigènes modifiés selon l'invention permet d'obtenir, chez l'individu traité, une immunité efficace contre l'antigène original exprimé par le cancer.

Granted: 2008-06-17
Abstract: A medical extractor comprising a canula assembly having an annularly expanding and retracting gripping and releasing mechanism on the distal end thereof and a moving assembly on the proximal end thereof. The arrangement is such that a manual movement of the moving assembly in one direction effects a longitudinally outward movement of an annular array of longitudinally movable wire flexure elements within an annular array of longitudinally fixed tubular flexure elements to cause the fixed flexure elements to flex transversely outwardly and create an annularly expanded condition defined by an annular series of transversely outwardly flexed fixed flexure elements interconnected at their ends by an annular series of arcuately outwardly flexed portions of the movable flexure elements. A manual movement in the opposite direction effects a longitudinally inward movement of the movable flexure elements to cause the expanded condition to progressively retract during which the outwardly flexed fixed flexure elements are progressively less flexed transversely outwardly and the arcuately flexed portions of the movable flexure elements have a progressively less arcuate extent.
