BACKGROUND AND AIMS Hepatic stellate cells (HSC) are activated by liver injury to become proliferative fibrogenic myofibroblasts. This process may be regulated by the sympathetic nervous system (SNS) but the mechanisms involved are unclear. METHODS We studied cultured HSC and intact mice with liver injury to test the hypothesis that HSC respond to and produce SNS neurotransmitters to promote ...

Neurotransmitters (NTs) are known as endogenous chemical messengers with important roles in the normal functioning of central and peripheral nervous systems. Abnormal levels certain NTs, such dopamine, serotonin epinephrine, have been linked several neurodegenerative diseases (such Alzheimer’s disease, Parkinson’s disease Huntington’s disease). To date, various strategies employed for quantitat...

in vitro culture systems using bone marrow cells from balb/c mice were set up in medium supplemented with spleen-derived medium. bone marrow cells grown in spleen-derived medium gave rise to cultures containing >97% mast cells. the cells were used in polarisation chemotaxis assays with the intention of determining the effect of nerve tissue-derived neurotransmitters on mast cell migration. some...

There is no question about the fact that astrocytes and other glial cells release neurotransmitters that activate receptors on neurons, glia and vascular cells, and that calcium is an important second messenger regulating the release. This occurs in cell culture, tissue slice and in vivo. Negative results from informative experiments designed to test the mechanism of calcium-dependent neurotran...

Over the past two decades, the classical understanding of steroid action has been updated to include rapid, membrane-initiated, neurotransmitter-like functions. While steroids were known to function on very short time spans to induce physiological and behavioral changes, the mechanisms by which these changes occur are now becoming more clear. In avian systems, rapid estradiol effects can be med...

There has been extensive research in the recent past looking into the molecular basis and mechanisms of the biological clock, situated in the suprachiasmatic nuclei (SCN) of the anterior hypothalamus. Neurotransmitters are a very important component of SCN function. Thorough knowledge of neurotransmitters is not only essential for the understanding of the clock but also for the successful manip...

after alzheimer's disease, parkinson's disease is the most common nerve-damaging disease. parkinson's is a progressive and chronic disease where cells secrete dopamine-cut black flesh and in the absence of dopamine in the brain destroyed the irregular body movements. man eats the food that causes the formation of the neurotransmitters. tthree neurotransmitters: dopamine, serotoni...

Detection of neurotransmitters is an analytical challenge and essential to understand neuronal networks in the brain and associated diseases. However, most methods do not provide sufficient spatial, temporal, or chemical resolution. Near-infrared (NIR) fluorescent single-walled carbon nanotubes (SWCNTs) have been used as building blocks for sensors/probes that detect catecholamine neurotransmit...

If this book were untitled, I would conclude that it was one of the best available textbooks on basic and clinical neuropharmacology. Part 1 is an up-to-date and comprehensive review of neurotransmitter systems and Part 2 is one of the best sets of reviews of psychophysiology and cognitive neurochemistry at this level of publication. Part 3 includes excellent reviews of the clinical pharmacolog...
