(EN) METHODS OF IDENTIFYING IMMUNOMODULATORY GENES
(FR) PROCÉDÉS D'IDENTIFICATION DE GÈNES IMMUNO-MODULATEURS
Abstract
(EN)
Disclosed herein are methods for identifying immunomodulatory genes. In some embodiments, the method comprises of screening a candidate gene comprising: a) expressing an exogenous cellular receptor, or a functional portion thereof, in a plurality of immune cells; b) introducing into said plurality of immune cells: i. a guiding polynucleic acid, or a nucleic acid encoding said guiding polynucleic acid, wherein said guiding polynucleic acid targets said candidate gene; and ii. an exogenous nuclease, or a nucleic acid encoding said exogenous nuclease; thereby generating a plurality of engineered immune cells comprising a genomic disruption in said candidate gene; c) contacting said plurality of engineered immune cells with a plurality of cells expressing a cognate antigen of said exogenous cellular receptor or a functional portion thereof, thereby performing an in vitro assay; and d) determining a readout of said in vitro assay.

L'invention concerne des procédés d'identification de gènes immuno-modulateurs. Dans certains modes de réalisation, le procédé comprend le criblage d'un gène candidat comprenant : a) l'expression d'un récepteur cellulaire exogène, ou d'une portion fonctionnelle de celui-ci, dans une pluralité de cellules immunitaires ; b) l'introduction dans ladite pluralité de cellules immunitaires : i. d'un acide polynucléique de guidage ou d'un acide nucléique qui code ledit acide polynucléique de guidage, ledit acide polynucléique de guidage ciblant ledit gène candidat ; et ii. d'une nucléase exogène ou d'un acide nucléique qui code ladite nucléase exogène ; ce qui permet de générer une pluralité de cellules immunitaires modifiées comprenant une interruption génomique dans ledit gène candidat ; c) la mise en contact de ladite pluralité de cellules immunitaires modifiées avec une pluralité de cellules exprimant un antigène parent dudit récepteur cellulaire exogène ou d'une portion fonctionnelle de celui-ci, réalisant ainsi un dosage in vitro ; et d) la détermination d'une lecture dudit dosage in vitro.
