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.
