Abstract

La glándula tiroides juega un papel esencial en la homeostasis metabólica. La enfermedad de Graves y la tiroiditis de Hashimoto tienen una prevalencia de 2% y constituyen las entidades autoinmunes más frecuentes en humanos. Estas entidades se originan por la pérdida de la tolerancia a los antígenos tiroideos en personas genéticamente susceptibles en asociación con factores ambientales.
Se ha obtenido un importante progreso en el conocimiento de los genes responsables de las enfermedades tiroideas autoinmunes. Además, se ha profundizado en los últimos años en los factores y procesos comprometidos en la ruptura de la tolerancia a los antígenos propios.
Hasta el momento no existe evidencia de que la enfermedad de Graves espontánea se presente en especies diferentes a la humana, en cambio la tiroiditis autoinmune ocurre espontáneamente en ciertos mamíferos y aves. La comprensión de la tolerancia a los autoantígenos y su ruptura que conduce a la producción de la autoinmunidad tiroidea puede esclarecerse con el examen de las siguientes preguntas en ambas entidades, la espontánea y la inducida en animales experimentales.
