Title
(EN) A GROUP OF CHIMERIC ANTIGEN RECEPTORS (CARS)
(FR) GROUPE DE RÉCEPTEURS D'ANTIGÈNES CHIMÉRIQUES (CAR)
Abstract
(EN)
Disclosed is a group of chimeric antigen receptors (CARs) consisting of two, three or four CAR molecules, wherein each member of the group of CARs is different in its amino acid sequence from one another, and wherein each of the CAR molecules of the group comprise at least a transmembrane domain and an ectodomain, wherein the ectodomain comprises one or two antigen binding moieties and/or one or two binding sites to which other polypeptides each comprising at least an antigen binding moiety are able to bind; wherein the ectodomain of each CAR molecule of the group in its prevalent conformation is free of cysteine amino acid moieties which are able to form intermolecular disulphide bonds with other CAR molecules of the group, respectively, and wherein each CAR molecule of the group comprises at least one heterodimerization domain.
(FR)
L'invention concerne un groupe de récepteurs d'antigènes chimériques (CAR) constitué de deux, trois ou quatre molécules CAR, chaque élément du groupe de CAR étant différent des autres par sa séquence d'acides aminés, et chacune des molécules CAR du groupe comprenant au moins un domaine transmembranaire et un ectodomaine, l'ectodomaine comprenant une ou deux fractions de liaison à l'antigène et/ou un ou deux sites de liaison auxquels d'autres polypeptides comprenant chacun au moins une fraction de liaison à l'antigène sont capables de se lier; l'ectodomaine de chaque molécule CAR du groupe dans sa conformation prévalente étant exempt de fractions d'acide aminé cystéine qui sont capables de former des ponts disulfure intermoléculaires avec d'autres molécules CAR du groupe, respectivement, et chaque molécule CAR du groupe comprenant au moins un domaine d'hétérodimérisation.
