La leptina y la regulación del peso corporal

Abstract

El descubrimiento de la leptina, además de revolucionar los conocimientos fisiológicos sobre la regulación del peso corporal, ha despertado el interés por el tejido graso como órgano endocrino y por su activa contribución al establecimiento de los depósitos energéticos. La leptina, secretada principalmente por los adipocitos, interacciona con receptores hipotalámicos, siendo capaz de activar diversas rutas neuroendocrinas encargadas de controlar el balance entre la ingesta y el gasto energético. Como otras citoquinas, la leptina es también capaz de intervenir en la compleja regulación de diversos aspectos metabólicos. Desde el hallazgo de que la placenta, la mucosa gástrica o las células estelares del hígado son lugares de producción de leptina, un gran abanico de funciones se atribuyen a esta hormona; ya que parece favorecer el desarrollo fetal y en el estómago podría actúar como factor de saciedad o participar en las señales aferentes mediadas por el vago. La leptina interviene además en las respuestas inmune e inflamatoria, en la reproducción, en procesos relacionados con la angiogénesis, control de la presión arterial, lipólisis, etc. El presente artículo revisa el papel de la leptina en la regulación del peso corporal, así como diversos aspectos relacionados con la obesidad.
