Title (EN) METHOD AND PREPARATION FOR SORTING OUT T EFFECTOR CELLS USING ANTI-CD127 ANTIBODIES FOR APPLICATIONS IN CELL THERAPY
(FR) PROCÉDÉ ET PRÉPARATION PERMETTANT DE TRIER DES LYMPHOCYTES T EFFECTEURS À L'AIDE D'ANTICORPS ANTI-CD127 POUR DES APPLICATIONS EN THÉRAPIE CELLULAIRE
Abstract:
(EN) The invention relates to methods and preparations for sorting out T effector cells from human leukocytes using anti-CD127 antibodies. Accordingly the invention relates to the use of anti-CD127 antibodies enabling discriminative depletion of subpopulations of Tregulatory cells expressing CD127+ at low levels in a population of human T lymphocytes in order to enable the use of the recovered selected cell preparations comprising essentially Teffector cells as lymphocytes and preferably devoid of Tregulatory cells, for improved efficacy in particular when administered to a patient for therapy.
(FR) L'invention concerne des procédés et des préparations permettant de trier des lymphocytes T effecteurs à partir de leucocytes humains à l'aide d'anticorps anti-CD127. Par conséquent, l'invention concerne l'utilisation d'anticorps anti-CD127 permettant une déplétion discriminative de sous-populations de lymphocytes T régulateurs exprimant CD127+ à de faibles niveaux dans une population de lymphocytes T humains afin de permettre l'utilisation des préparations cellulaires sélectionnées récupérées comprenant essentiellement des lymphocytes T effecteurs en tant que lymphocytes et de préférence dépourvues de lymphocytes T régulateurs, pour une efficacité améliorée en particulier lorsqu'elle est administrée à un patient en vue d'une thérapie.
