L'interleukine 1 bêta est une isoforme de l'interleukine 1. Elle a un rôle pro-inflammatoire. Son gène est IL1B situé sur le chromosome 2 humain.

Structure

L'interleukine 1 possède deux principales isoformes. L'interleukine 1 alpha est fixée à la cellule tandis que l'interleukine 1 bêta diffuse dans le sang permettant une action à distance.

La protéine est fabriquée sous forme d'une pro-interleukine 1 bêta qui va être clivée par la caspase 1, l'un des composants de l'inflammasome, en interleukine 1 bêta.

Rôles

IL-1β favorise la chimiorésistance dans le cancer et est un acteur clé dans le microenvironnement tumoral^[5]^,^[6].

Elle joue un rôle dans la formation de l'athérome^[7]. Son taux sanguin, mesuré lors d'un infarctus du myocarde est corrélé avec un risque plus important de mortalité ou de complications^[8].

Cible thérapeutique

Le canakinumab est un anticorps monoclonal dirigé contre l'interleukine-1 bêta.
