Adiponectina: Una adipocitoquina con múltiples funciones protectoras

Abstract

Actualmente, se considera que el tejido adiposo es un órgano dinámico involucrado en muchos procesos fisiológicos y metabólicos. Expresa y secreta una gran variedad de péptidos activos conocidos como adipocitoquinas que actúan en forma local y sistémica. Además, expresa numerosos receptores que le permiten responder a señales aferentes de diferentes órganos endocrinos y del sistema nervioso central. La adiponectina es una hormona de 30 kDa producida exclusivamente por el tejido adiposo. A diferencia de las demás adipocitoquinas conocidas, sus niveles se encuentran disminuídos en estados asociados con resistencia insulínica, tal como obesidad, diabetes tipo 2 y síndrome metabólico. A esta proteína se le ha atribuído un rol antidiabético, antiinflamatorio y antiaterogénico. El objetivo de este trabajo es realizar una revisión acerca de la estructura, las funciones biológicas, el o los posibles mecanismos de acción, las implicancias fisiopatológicas y las posibles aplicaciones de la evaluación de los niveles de esta adipocitoquina a nivel clínico.

The adipose tissue is considered a dynamic organ, which is involved in a wide range of physiological and metabolic processes. This tissue expresses and secretes a variety of bioactive peptides, known as adipocytokines, which act both at the local and at the systemic levels. The adipose tissue also expresses several receptors that allow it to respond to afferent signals from different endocrine organs, as well as form the central nervous system. Adiponectin is a 30 kDa hormone exclusively secreted by adipocytes. Unlike the other known adipocytokines, its concentration is reduced in conditions associated to insulin resistance, like obesity, type2 diabetes and metabolic syndrome. Several studies suggest that adiponectin has antidiabetic, antiinflammatory and antiatherogenic actions. The aim of this work is to review the new advances in structure, biological functions, mechanisms of action and potential clinical applications of adiponectin evaluation.
