The present invention provides a strategy for TCR-display that closely mimics the in vivo situation, meaning at least a stable expression of TCRs to he displayed in mammalian cells exemplified by retroviral insertion of a T cell receptor library into a TCR-negative T cell host. Such mammalian cell line TCR libraries, especially T cell line-displayed TCR libraries woud not only allow the selection of desirable TCRs by biochemical means. but also offer the possibility to directly test the functional behavior of selected TCRs. By generating a TCR library that is diersified in its CDR3beta structure, we were able to select novel TCRs that either share specificity with the parental TCR, or that have acquired a specificity for a variant T cell epitope. A change in TCR specificity can be thought of as an increase in TCR affinity for the variant epitope.

L'invention concerne une technique permettant d'afficher des TCR, qui imite de près la situation in vivo, ce qui signifie qu'au moins une expression stable de TCR sera affichée dans des cellules mammifères, illustrée par l'introduction rétrovirale d'un TCR dans un hôte de cellule T à TCR négatif. Ces banques de TCR de lignes cellulaires mammifères, notamment des banques de TCR à lignes de cellules T affichées, permettraient non seulement la sélection de TCR adéquats par des moyens chimiques, mais offriraient aussi la possibilité de tester directement le comportement fonctionnel de TCR sélectionnés. La production d'une banque de TCR diversifiée dans sa structure CDR3 beta nous a permis de sélectionner des nouveaux TCR qui partagent la même spécificité que le TCR parental, ou qui ont acquis une spécificité pour un épitope de cellule T variant. Une modification de la spécificité des TCR peut être considérée comme une augmentation de l'affinité des TCR pour l'épitope variant.
