Abstract

Agente para el tratamiento y/o la prevencion de una enfermedad autoinmune, un agente para la formacion de celulas T reguladoras (Treg) en un ser vivo, as¡ como diversos procedimientos, en los que se usan los agentes segun la invencion. Reivindicacion 1: Uso de una mute¡na de interleuquina-2 humana (mute¡na de hIL-2) o una de sus partes, que est  numerada segun la hIL-2 de tipo salvaje y que presenta una sustitucion de amino cido en al menos una de las posiciones 20, 88 o 126, para preparar un medicamento para el tratamiento y/o la prevencion de una enfermedad autoinmune. Reivindicacion 2: Uso de acuerdo con la reivindicacion 1, caracterizado porque por sustitucion en la posicion 88 se intercambia una asparagina por arginina (hIL-2-N88R), o por una glicina (hIL-2-N88G) o por una isoleucina (hIL-2-N88I). Reivindicacion 3: Uso de acuerdo con la reivindicacion 1 o 2, caracterizado porque por sustitucion en la posicion 20 se intercambia un  cido asp rtico por una histidina (hIL-2-D20H) o por una isoleucina (hIL-2-D20H) o por una tirosina (hIL-2-D20Y). Reivindicacion 4: Uso de acuerdo con una de las reivindicaciones precedentes, caracterizado porque por sustitucion en la posicion 126 se intercambia una glutamina por una leucina (hIL-2-Q126L). Reivindicacion 7: Uso de acuerdo con una de las reivindicaciones precedentes, caracterizado porque el medicamento presenta adicionalmente un inmunosupresor. Reivindicacion 11: Medicamento para el tratamiento y/o la prevencion de una enfermedad autoinmune, caracterizado porque presenta la mute¡na de hIL-2 o una parte de ella segun el uso de acuerdo con una de las reivindicaciones 1 a 10. Reivindicacion 21: Agente para la formacion de celulas T reguladoras (Treg) en un ser vivo, caracterizado porque presenta la mute¡na de hIL-2 o una parte de ella segun el uso de acuerdo con una de las reivindicaciones 12 a 20.
