Glutamate transporter

Optogenetic stimulation of LH neurons expressing vesicular GABA transporter (LHVGat ; putative GABA neurons) induces feeding and optical self-stimulation, whereas selective ablation of these neurons reduces feeding, body weight gain, and motivation to obtain palatable reward124. VTA MC3R-GABA may decrease feeding and/or food reward by direct inhibition of LHVgat neurons. Additionally, VTA MC3R expressing neurons may affect feeding and food reward by indirect action on LH GABA neurons. Activation of AcbSh D1R neurons projecting to LH GABA neurons results in feeding bout termination101. VTA MC3R-DA neurons may decrease feeding and food reward by indirect inhibition of LHVGat neurons via activation of AcbSh D1R…

value. Patrick catches onto her motivation but unfortunately can only echo her concerns as true. He too feels pointless in it all. What can Patrick do to change the nature of their limbo? He knows the solution is beyond his powers. Marina hums the tune once more. It’s a tune that requires Patrick to answer. Patrick has a eureka moment! He expands upon his thoughts in song however to himself. The song turns into a plot device explaining a series of transporter modifications he could…

Monosodium glutamate is a taste enhancing vegetable protein. At the time of discovery, MSG was thought to be safe since it was an amino acid, a natural substance. The amount of MSG added to foods has doubled in every decade since the 1940's and by 1972, 262,000 metric tons of MSG were produced. In 1957 two ophthalmologists, Lucas and Newhouse decided to test MSG on infant mice in an effort to study the effects of MSG and its correlation with an eye disease known as hereditary retinal dystrophy.…

Statistical Manual of Mental Disorders, 2000). For Anxiety its symptoms must remain persist for at least six months, with three or more of the six symptoms being present more days than not. Controlling worrying becomes increasingly difficult. It also incldes feeling restlessness, easily fatigued, concentration diminished, irritable, muscle tension and sleep disturbance. (Diagnostic and Statistical Manual of Mental Disorders, 2000). Most people that experience negative life events do not…

Have you ever been sitting in line for a fast food restaurant and wondered what the long term effects the food we are about the purchase could be making on our bodies? Fast food has many different additives that are coloring our foods and preservatives such as sodium nitrate, MSG (monosodium glutamate), and even feathers and hair that are commonly labeled as L-cysteine and more that are in many different foods that most individuals consume on a daily basis. Fast food may be good, but it has…

In spite of ingestion of these additional commercially produced glutamates, our body metabolizes this glutamate in the same way it does with the other glutamates found naturally in foods. What that means is that our body does not distinguish between naturally occurring glutamates or the MSG found in a bottle of ketchup. Interestingly, a research report not suggests that glutamate from food or MSG is important for a normal digestive function. (Food Insight, 2009) In 1958 the FDA (U.S. Food and…

After astrocytes remove glutamate from the ECS, glutamate must be isolated and degraded. Glutamate transporters are bidirectional, so intracellular elevations of glutamate levels will lead to an electrochemical gradient-mediated release if the molecule is not destroyed. If glutamate release is unregulated glutamate accumulates in the ECS and impairs the survival of neurons. Glutamate dehydrogenase (GDH) helps degrade glutamate into a-ketoglutarate, an intermediary in the tricarboxylic acid (TCA)…

mechanisms that are at the root of the pathophysiology of ALS. Some of these include: (1) the oxidative damage on cells by SOD1 (superoxide dismutase), and (2) increased glutamate concentration in the cerebrospinal fluid…

OFF center cells are hyperpolarized by the same stimuli. Both cell types repolarize by light stimulation of the peripheral receptive field outside the center. Some bipolar cells postsynapticaly are only cones, some are only rods while other can receive input from both rods and cones. Different bipolar cell types express different glutamate receptors. The axon terminals of bipolar cells can be either monostratified or mulistratified. The cells are also differentiated into midget or diffuse type…

Researchers experiment with brain cells to understand the different pathways. As the follow experiment where researchers put glutamate in a culture where there were neurons and astrocytes. After a glucose use by cells, they saw an inhibition of the glucose transport into the neurons and this inhibition was stronger with add of lactate in the culture. This experiment show us that glutamate inhibited glucose transport into the neurons and in consequence inhibited glycolysis, and this is why it…
