The present invention relates to immunologically active molecules comprising an epitope of interest, more than one major histocompatibility complex class II element, and an immunoglobulin constant region element, wherein the epitope is comprised in a fusion protein which comprises a major histocompatibility class II element, wherein each major histocompatibility class II element comprises two non-covalently associated chains comprising extracellular domains of a major histocompatibility complex class II protein, and wherein the major histocompatibility class II elements are covalently joined by one or more disulfide linkages present in the immunoglobulin constant region element. The molecules of the invention may be used to selectively eliminate T cells bearing TCRs which react with the epitope of interest in the context of the major histocompatibility complex class II element, and therefore may be used to eliminate or reduce specific T cell populations, for example, but not by way of limitation, in the treatment of an autoimmune disease and/or a graft-versus host disease.

L'invention concerne des molécules immunologiquement actives, qui comprennent un épitope d'intérêt, plus d'un élément de la classe II du complexe majeur d'histocompatibilité (CMH) et un élément de la région constante d'une immunoglobuline. L'épitope est inclus dans une protéine de fusion qui comprend un élément de la classe II du CMH constitué de deux chaînes associées de manière non covalente, renfermant les domaines extracellulaires d'une protéine de la classe II du CMH. Les éléments de la classe II du CMH sont réunis de manière covalente par un ou plusieurs ponts disulfures présents dans l'élément de la région constante de l'immunoglobuline. Les molécules de l'invention peuvent être utilisées pour éliminer sélectivement les lymphocytes T portant des TCR, qui réagissent avec l'épitope d'intérêt dans le contexte de l'élément de la classe II du CMH, et donc pour éliminer ou réduire les populations de lymphocytes T spécifiques, entre autres, dans le traitement d'une maladie auto-immune et/ou d'une maladie de rejet de greffe.
