Excitotoxicity, calcium and mitochondria: a triad in synaptic neurodegeneration
AbstractGlutamate is the most commonly engaged neurotransmitter in the mammalian central nervous system, acting to mediate excitatory neurotransmission. However, high levels of glutamatergic input elicit excitotoxicity, contributing to neuronal cell death following acute brain injuries such as stroke and trauma. While excitotoxic cell death has also been implicated in some neurodegenerative disease models, the role of acute apoptotic cell death remains controversial in the setting of chronic neurodegeneration. Nevertheless, it is clear that excitatory synaptic dysregulation contributes to neurodegeneration, as evidenced by...

Amyotrophic Lateral Sclerosis (ALS) with Laboratory Abnormalities of Unknown Significance (LAUS) --Where Does It Begin and Where Does It End? (P4.144)
CONCLUSIONS: Further detailed analysis of progression rate by site of onset, sex, age, treatment will require assimilation of clinic-based datasets of properly analyzed ALS-LAUS patients from multiple clinic sites. The appropriate role of IVIg in ALS-LAUS patients requires further study following explication of the natural history of these patients compared with non-ALS-LAUS patients. The determination as to whether auto-antibodies to additional antigens may play a role in the progression rate of ALS-LAUS compared with sporadic ALS needs to be systematically studied.
