RESUMENSe ha planteado que la hormona de crecimiento (GH) y la Prolactina (PRL) pueden intervenir en procesos infecciosos como inmunomoduladores vía receptores específicos; revelando una conexión entre el sistema inmune y el sistema endocrino en los tejidos, donde actúan como citoquinas a través de diferentes rutas de señalización. Igualmente, la hepcidina (HAMP), hormona producida en los hepatocitos como respuesta al exceso de hierro y a estímulos inflamatorios, es considerada un enlace entre el metabolismo del mineral, la defensa del hospedero y los procesos inflamatorios, debido a su capacidad de privar del hierro a los microorganismos. Se sugiere que en un proceso infeccioso, la síntesis, secreción y regulación de GH ocurre a través de la producción de citoquinas como factor de necrosis tumoral alfa (TNF-α) e interleuquina-1 beta (IL-1β), las cuales actúan en el hipotálamo, estimulando la liberación ya sea de la hormona liberadora de somatotropina o de somatostatina; por otro lado, se ha reportado que células linfoides, incluyendo linfocitos T y B y células dendríticas, producen GH, PRL biológicamente activa con propiedades inmunoreguladoras.Palabras clave: Hormona de crecimiento animal, prolactina, sistema inmune (Fuente:CAB). ABSTRACTIt has been proposed that growth hormone (GH) and prolactin (PRL) may act as immunomodulators in infectious processes via specific receptors, revealing a connection between the immune and endocrine systems in the tissues where they act as cytokines through different signaling pathways. Similarly, hepcidin (HAMP), a hormone produced in hepatocytes in response to excess iron and inflammatory stimuli, is considered a link between mineral metabolism, host defense and inflammatory processes because of its ability to deprive microorganisms of iron. It is suggested that in an infectious process, synthesis, and regulation of GH secretion occurs through the production of cytokines such as necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β), which act in the hypothalamus by stimulating the release of either somatostatin or somatotropin hormones; on the other hand, it has been reported that lymphoid cells including T and B lymphocytes and dendritic cells produce GH, and biologically active PRL with immunoregulatory properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
