El envejecimiento produce la declinación de la capacidad funcional y morfológica de los sistemas endócrino, nervioso e inmune, asociada con el descenso de la habilidad para mantener la homeostasis. Durante este proceso se producen alteraciones sobre los diferentes tipos celulares de la adenohipófisis de la rata. El presente diseño experimental permite lograr un modelo equivalente al de una vida humana de 80 a 100 años y analiza los cambios ultraestructurales y cuantitativos de las poblaciones celulares secretoras de hormonas hipofisiarias. Se utilizaron ratas machos y hembras Sprague-Dawley.Ageing determines a morphological-functional delay of the immunoendocrine system, together with a decrease of the ability to maintain homeostasis.
