Un estudio de más de 1 millón de embarazos en Finlandia informa que los niveles elevados de un metabolito del insecticida prohibido DDT en la sangre de las mujeres embarazadas están relacionados con un mayor riesgo de autismo en la descendencia.
#1 Factor que como todos los factores/vectores no implica que sea ni el vector principal ni que sea necesario para desencadenar el fallo genético que causa el autismo.
"The researchers offer two reasons for their observation that maternal exposure to DDE was related to autism while maternal PCB exposure was not. First, maternal DDE is associated with low birthweight, a well-replicated risk factor for autism. In contrast, maternal PCB exposure has not been related to low birthweight. Second, they point to androgen receptor binding, a process key to neurodevelopment. A study in rats found DDE inhibits androgen receptor binding, an outcome also seen in a rat model of autism. In contrast, PCBs increase androgen receptor transcription. "

¿Y por qué hay autismo en paises donde no se usa el DDT?
Pensaba que ya habían aclarado este tema los genetistas.

Es una magufada, el autismo es genetico.
Esto solo da alas a los antivacunas y demas movimiento magufos.
