Genetic susceptibility to methylmercury developmental neurotoxicity matters
Epidemiological studies have demonstrated the developmental neurotoxicity associated with prenatal methylmercury exposure (Grandjean and Landrigan, 2006); However, susceptibility to methylmercury toxicity may be increased by genetic factors. This observation raises the question of possible dependence of developmental neurotoxicity on genetic predisposition. A few years ago, a National Research ...
متن کاملMethylmercury exposure and developmental neurotoxicity
We are concerned that certain aspects of the systematic review on methylmercury (MeHg) exposure from seafood consumption and the risk of developmental neurotoxicity published in the Bulletin of World Health Organization could be misinterpreted.1 Specifically, the review does not address the issue of whether naturally-occurring, background levels of prenatal exposure to MeHg from maternal fish c...
متن کاملMethylmercury neurotoxicity & antioxidant defenses.
Neurotoxicity induced by methylmercury (MeHg) increases the formation of reactive radicals and accelerates free radical reactions. This review summarizes recent findings in the MeHg-induced formation of free radicals and the role of oxidative stress in its neurotoxicity. Oxidative stress on CNS can produce damage by several interacting mechanisms, including mitochondrial damage with increase in...
متن کاملMechanisms of methylmercury-induced neurotoxicity.
Mercury in both organic and inorganic forms is neurotoxic. Methylmercury (MeHg) is a commonly encountered form of mercury in the environment. Early electrophysiological experiments revealed that MeHg potently affects the release of neurotransmitter from presynaptic nerve terminals. Recently, the hypothesis that these alterations may be mediated by changes in the intracellular concentration of C...
متن کاملGenetic-based, differential susceptibility to paraquat neurotoxicity in mice.
Paraquat (PQ) is an herbicide used extensively in agriculture. This agent is also suspected to be a risk factor for Parkinson's disease (PD) by harming nigro-striatal dopamine neurons. There is likely, genetic-based, individual variability in susceptibility to PQ neurotoxicity related PD. In this study, we measured the delivery of PQ to the brain after three weekly injections of PQ at 5 mg kg(-...
