This line investigates the neural mechanisms involved in the neurotoxicity of environmental toxicants of relevance for the public health by using in vitro neural systems. The primary target is the identification and evaluation of neurotoxic agents and the characterization of the induced neuronal alterations, some of them common to underlying mechanisms of several neural and neurodegenerative diseases. Alterations of the inhibitory GABAergic and excitatory glutamatergic neurotransmission, cell proteome and mechanisms of oxidative stress are studied. At present we are focused on the study of pesticides (organochlorine and organophosphate pesticides) and of metals (organic derivatives of mercury like methylmercury). We foresee to initiate studies on the safety of nanomaterials with regards to the nervous system. We are also developing in vitro models and strategies to predict human toxicity, of great interest for the EU-REACH programme for the testing of the safety/toxicity of new and existing compounds for the human health. Especially, we are focused on the study of compounds interacting with the GABA-A receptor as this receptor is the target for both convulsant and depressant toxicant and pharmaceutical drugs.
The subline is a group member of the CIBER de Epidemiología y Salud Pública (CIBERESP), giving a projection of the investigations in the area of the Risk Assessment and Human Health.
