Abstract
(EN)
The present disclosure provides a binding protein comprising: a polypeptide heavy chain comprising: VH1-(X1)n-VH2-CH (X2)y wherein VH1 is a first variable domain, VH2 is a second variable domain, CH is a constant domain, X1 represents an amino acid or peptide, X2 represents an Fc region, n is 0 or 1 and y is independently 1 or 2, and a polypeptide light chain comprising: VL1-(X1)n-VL2-C wherein VL1 is a first variable domain, VL2 is a second variable domain, C is a constant domain, X1 represents an amino acid or peptide and n is 0 or 1, wherein the heavy chain and light chain are aligned such that VH1 and VL1 form a first binding domain, and VH2 and VL2 form a second binding domain and wherein: there is a disulfide bond between VH1 and VL1, and/or there is a disulfide bond between VH2 and VL2, and use thereof in treatment.

L'invention concerne une protéine de liaison qui comprend: une chaîne lourde polypeptidique comprenant VH1-(X1)n-VH2-CH (X2)y, VH1 représentant un premier domaine variable, VH2 représentant un deuxième domaine variable, CH représentant un domaine constant, X1 représentant un acide aminé ou un peptide, X2 représentant une région Fc, n représentant 0 ou 1 et y représentant indépendamment 1 ou 2; et une chaîne légère polypeptidique comprenant VL1-(X1)n-VL2-C, VL1 représentant un premier domaine variable, VL2 représentant un deuxième domaine variable, C représentant un domaine constant, X1 représentant un acide aminé ou un peptide et n représentant 0 ou 1. La chaîne lourde et la chaîne légère sont alignées de sorte que VH1 et VL1 forment un premier domaine de liaison, et VH2 et VL2 forment un deuxième domaine de liaison; et une liaison disulfure est présente entre VH1 et VL1, et/ou une liaison disulfure est présente entre VH2 et VL2. L'invention concerne aussi l'utilisation thérapeutique de cette protéine.
