Abstract

L'invention concerne des compositions, des procédés et des utilisations d'un virus recombinant et/ou d'un vecteur viral recombinant codant pour un anticorps ou un fragment d'anticorps distinct généré à partir d'une bibliothèque d'acides nucléiques à haute diversité. De préférence, le virus recombinant est génétiquement modifié et est un faible virus immunogène, tel qu'un adénovirus à délétion E2b. La bibliothèque d'acides nucléiques à haute diversité comprend (1) une sous-bibliothèque de VH-CDR1/2, (2) une pluralité de sous-bibliothèques de VH-CDR3 et (3) une sous-bibliothèque de VL ou est dérivée de ces dernières, toutes comprenant une pluralité d'éléments. De préférence, chaque élément des sous-bibliothèques comprend au moins une cassette aléatoire ayant une pluralité de positions de base dégénérées. Selon un mode de réalisation particulièrement préféré, au moins certaines parties d'au moins deux éléments de la sous-bibliothèque de VH-CDR1/2, de la pluralité de sous-bibliothèques de VH-CDR3 et de la sous-bibliothèque de VL sont recombinées pour former un élément de bibliothèque d'expressions dans une bibliothèque d'expressions, chaque élément de la bibliothèque d'expressions codant un anticorps ou un fragment d'anticorps distinct.
