Células que mantienen sana a la piel más sucia.

from Cienciaes.com

Las paredes intestinales deben permitir la absorción de sustancias nutritivas, como sucede en el intestino delgado, o la reabsorción de líquidos, como sucede en el colon distal, la zona del intestino grueso donde se forman las heces. Esta última es la parte del intestino más sucia y más peligrosa. En ella vive una ingente cantidad de bacterias, virus bacteriófagos y hongos que vierten al intestino sus deshechos y compuestos tóxicos. La absorción de líquidos y la formación de las heces es llevada a cabo por una sola capa de células epiteliales del colon distal que controlan el paso de las sustancias entre ellas. Ahora, un conjunto internacional de investigadores comprueban que los macrófagos, unas células conocidas por ejercer un control férreo frente al crecimiento de hongos y bacterias, se colocan debajo de la barrera formada por las células epiteliales y emiten prolongaciones entre el estrecho espacio que las separa. Si detectan una cantidad de toxinas superior a lo aconsejable, avisan a las células epiteliales para limitar su absorción y preservar así su vida y la integridad de la barrera epitelial intestinal.
