Diethylstilbestrol Exposure in Neonatal Mice Induces Changes in the Adulthood in the Immune Response to Taenia crassiceps without Modifications of Parasite Loads
Industrial growth has increased the exposition to endocrine disruptor compounds (EDC’s), which are exogenous agents with agonist or antagonist action of endogenous steroid hormones that may affect the course of parasite infections. We wanted to determine if the exposure to diethylstilbestrol (DES),...

Industrial growth has increased the exposition to endocrine disruptor compounds (EDC’s), which are exogenous agents with agonist or antagonist action of endogenous steroid hormones that may affect the course of parasite infections.
