Neurotoxicology

Abstract

Exposure to environmental neurotoxic metals, pesticides and other chemicals is increasingly recognized as a key risk factor in the pathogenesis of chronic neurodegenerative disorders such as Parkinson's and Alzheimer's diseases. Oxidative stress and apoptosis have been actively investigated as neurotoxic mechanisms over the past two decades, resulting in a greater understanding of neurotoxic processes. Nevertheless, emerging evidence indicates that epigenetic changes, protein aggregation and autophagy are important cellular and molecular correlates of neurodegenerative diseases resulting from chronic neurotoxic chemical exposure. During the Joint Conference of the 13th International Neurotoxicology Association and the 11th International Symposium on Neurobehavioral Methods and Effects in Occupational and Environmental Health, the recent progress made toward understanding epigenetic mechanisms, protein aggregation, autophagy, and deregulated kinase activation following neurotoxic chemical exposure and the relevance to neurodegenerative conditions were one of the themes of the symposium. Dr. Anumantha G. Kanthasamy described the role of acetylation of histones and non-histone proteins in neurotoxicant-induced neurodegenerative pr...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Alpha-Synuclein Aggregation (MDS)

Alpha-synucleins are small proteins that are believed to restrict the mobility of synpatic vesicles and inhibit neurotransmitter release. Aggregation of these proteins have been linked to several types of neurodegenerative diseases including dementia with Lewy bodies and Parkinson's disease. Here is the latest research on α-synuclein aggregation.

Parkinson's Disease & Autophagy (MDS)

Autophagy leads to degradation of damaged proteins and organelles by the lysosome. Impaired autophagy has been implicated in several diseases. Here is the role of autophagy in Parkinson’s disease.

Epidemiology of Aging

This feed focuses on epidemiology of aging and aging-related conditions, including Alzheimer’s disease, dementia, and age-associated cognitive impairment. Here is the latest research.

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Alzheimer's disease is a neurodegenerative disease. Discover genetic and epigenetic aspects of Alzheimer’s disease, including genetic markers and genomic structural variations with this feed.

Autophagy Networks

Autophagy is a lysosomal pathway that involves degradation of proteins and functions in normal growth and pathological conditions, through a series of complex networks. The catabolic process involves delivery of proteins and organelles to the lysosome. Here is the latest research on autophagy networks.
