Células de los islotes

(Islet Cells)

El páncreas contiene grupos de células que producen hormonas. Estos grupos se llaman “islotes”. Hay varios tipos de células en un islote. Por ejemplo, las células alfa producen la hormona llamada “glucagón”, que aumenta el nivel de glucosa (un tipo de azúcar) en la sangre. Las células beta generan la hormona insulina, que baja el nivel de glucosa. En la diabetes tipo 1, el sistema inmunológico del cuerpo destruye, por equivocación, las células beta. A causa de esta situación, el páncreas pierde la capacidad de producir insulina.
