Résumé
Initialement considéré comme un tissu de «stockage», relativement passif, cantonné aux fonctions physiques et énergétiques, le tissu adipeux (TA) s’est vu progressivement attribuer de nouvelles fonctions physiologiques «nobles» notamment dans le domaine de la régulation métabolique et endocrinienne et a gagné ainsi en considération. L’intérêt pour ce tissu se manifeste tout autant en pathologie puisque sa contribution aux pathogénies de l’obésité et de nombreuses maladies métaboliques ou systémiques est à présent bien reconnue. Nous proposons dans ce chapitre de décrire et de discuter d’une fonction longtemps passée inaperçue du TA: la fonction toxicologique. Le terme de fonction toxicologique recouvre en réalité plusieurs notions: la contribution à la défense de l’organisme contre les toxiques, un rôle de source endogène de toxiques plutôt délétère et, enfin, une situation de cible des toxiques expliquant une partie de leur pathogénie. Cette nouvelle fonction que nous proposons n’est certainement pas aussi étayée que les autres fonctions de ce tissu, mais elle suscite de plus en plus d’intérêt, de travaux et de discussions.
