Glutamate Excitotoxicity and Neurodegeneration [PDF]
Glutamate plays crucial roles in the physiology of the central nervous system as it can control many functions such as memory, learning, cognitive, emotional, endocrine and other visceral functions. In addition, glutamate is the major excitatory neurotransmitter in the mammalian central nervous system.

Inhibition of Mg2+ Extrusion Attenuates Glutamate Excitotoxicity in Cultured Rat Hippocampal Neurons. [PDF]
Magnesium plays important roles in the nervous system. An increase in the Mg2+ concentration in cerebrospinal fluid enhances neural functions, while Mg2+ deficiency is implicated in neuronal diseases in the central nervous system.

Background Stroke is a leading cause of death and disability worldwide. A major factor in brain damage following ischemia is excitotoxicity caused by elevated levels of the neurotransmitter glutamate.

Abstract Objectives Acute cerebral ischemia is characterized by several pathological processes evolving during time, which contribute to the final tissue damage. Secondary processes, such as prolonged inflammatory response, impaired mitochondrial function and oxidative stress, are responsible for the progression of brain injury to the peri‐infarct area,

In vivo co-ordinated interactions between inhibitory systems to control glutamate mediated hippocampal excitability. [PDF]
We present an overview of the long-term adaptation of hippocampal neurotransmission to cholinergic and GABAergic deafferentation caused by excitotoxic lesion of the medial septum.

Ceftriaxone preserves glutamate transporters and prevents intermittent hypoxia-induced vulnerability to brain excitotoxic injury. [PDF]
Hypoxia alters cellular metabolism and although the effects of sustained hypoxia (SH) have been extensively studied, less is known about chronic intermittent hypoxia (IH), commonly associated with cardiovascular morbidity and stroke.

Medroxyprogesterone acetate exacerbates glutamate excitotoxicity
We previously demonstrated that progesterone functions as a neuroprotective agent whereas medroxyprogesterone acetate (MPA; Provera) does not. Moreover, MPA antagonized the neuroprotective and neurotrophic outcomes induced by 17beta-estradiol (E2). Towards developing effective hormone therapies for protection against neurodegeneration, we sought to ...

Glutamate is one of the most prevalent neurotransmitters released by excitatory neurons in the central nervous system (CNS); however, residual glutamate in the extracellular space is, potentially, neurotoxic.

Alcohol use disorder (AUD) has been associated with neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease. Prolonged excessive alcohol intake contributes to increased production of reactive oxygen species that triggers neuroimmune ...

Glutamate excitoxicity is the key molecular mechanism which is influenced by body temperature during the acute phase of brain stroke. [PDF]
Glutamate excitotoxicity, metabolic rate and inflammatory response have been associated to the deleterious effects of temperature during the acute phase of stroke. So far, the association of temperature with these mechanisms has been studied individually.
