  • Patent number: 8722401
    Abstract: A method for the in vitro production of a cell population P? from a cell population P, the production requiring the presence of at least one factor which is expressed by feeder cells, wherein a) feeder cells proliferate at a temperature T1, b) proliferated feeder cells are contacted with the cell population P, c) the cell mixture obtained at step (b) is cultivated at a temperature T2 which is chosen such that the cell population P proliferates and the feeder cells do not proliferate, the at least one factor being expressed by the feeder cells, and d) the cell population P? so produced is recovered. Advantageously, the production consists in an expansion, the feeder cells are insect feeder cells and the cell population P to be expanded is a T lymphocyte population, preferably a Trl lymphocyte population.

  • Patent number: 7985409
    Abstract: The present invention relates to a method of treating or preventing atherosclerosis comprising administering to a mammal in need of such a treatment a) an antigen which has been used to activate in vitro a Tri cell population originating from said mammal, and b) the TO cell population activated by said antigen, said TO cell population being obtained from a CD4+ T lymphocyte population of said mammal.

  • Patent number: 7977093
    Abstract: An in vitro method for the obtention of a food- or auto-antigen specific Tr1 cell population from a leukocyte or a PBMC population, includes stimulating the PBMC or leukocyte population with the food- or auto-antigen, and recovering the food- or auto-antigen specific Tr1 cell population from the stimulated cell population. Preferably, the PBMC or leukocyte population is re-stimulated at least once with the same antigen after step (1), in the presence of IL-2 and at least one interleukin selected from the group consisting of IL-4 and IL-13. The in vitro method may further include a third step of expanding the recovered antigen-specific Tr1 cell population, advantageously by contacting them with feeder cells capable of expressing factors necessary for the expansion. Preferably, the feeder cells are recombinant insect feeder cells.

  • Patent number: 7771932
    Abstract: The invention relates to a method for identification of Tr1 lymphocyte regulators in a biological sample, based on the determination of the simultaneous presence of the molecular group CD4, CD18 and/or CD11a, CD49b and, where appropriate, by the demonstration of an over-expression of genes coding for the molecules CD4, PSGL-1, PECAM-1 and alphaV/beta3. The invention further relates to a method of quantification and a prognostic or diagnostic method for auto-immune or inflammatory diseases, based on said identification method. The invention also relates to an enrichment method for Tr1 lymphocyte regulators, based on the determination of the simultaneous presence of said molecules and, finally, an enriched composition from said enrichment method, for the treatment of an auto-immune or inflammatory disease, in particular Crohn's disease.
