Sentences with phrase «surrounding nerve cells»

This results in a chain reaction (a «storm») in which the surrounding nerve cells are stimulated to fire off a shower of signals of their own to various muscles of the body.
B12 helps to maintain the myelin sheath surrounding nerve cells, which make it possible for cells to communicate.
More than one hundred vitamin B6 - dependent enzymes have been identified, mostly involved in amino acid metabolism: for oxygen transport via hemoglobin synthesis; in blood sugar regulation via conversion of stored carbohydrate to energy; in the development of the myelin sheath surrounding nerve cells; in the conversion of alphalinoleic acid to the essential long - chain fatty acid DHA; 28 and in the synthesis of neurotransmitters, phospholipids and sphingolipids, the vitamin niacin from tryptophan, and other vital metabolites.5 In addition to its role in enzyme reactions, B6 appears to moderate the action of some steroid hormones such as the glucocorticoid hormones, which in turn influence the metabolism of protein, carbohydrate and lipids.5, 9 B6 also is a potent antioxidant, rivaling carotenoids and vitamin E in its ability to quench reactive oxidants in the body.29
Writing in 2014 in the European Journal of Neuroscience, Leuner and colleagues reported that in rats with symptoms of postpartum depression (induced by stress during pregnancy, a major risk factor for postpartum depression in women), nerve cells in the nucleus accumbens atrophied and showed fewer protrusions called dendritic spines — suggesting weaker connections to surrounding nerve cells compared with healthy rats.
The buildup of twisted tau deposits also destroys surrounding nerve cells and eventually wastes away vast swaths of brain tissue.
In this case, modified T cells destroy the myelin sheath surrounding nerve cells.
Research has shown that touch can also stimulate neurological development by promoting the growth of myelin, the substance that surrounds nerve cells.

It destroys myelin, the protective surface that surrounds some nerve cells.
MS, which afflicts millions of people worldwide, develops when the body's immune system attacks the protective myelin sheath that surrounds nerve cells.
This surrounds all nerve cells and protects them from damage, and can be important in preventing certain degenerative conditions, such as Alzheimer's and Parkinson's.

Not exact matches

Nerves are developing and are now surrounded by myelin that allows the nerve cells to exchange signals.
The image, a mysterious, gray blob surrounding a spot of intense red, was based on an electron - microscope photo of a neuromuscular junction (the connection between a nerve cell and a muscle) clipped from a magazine sometime in the 1980s.
One clear characteristic of MS is scarring of myelin, the protective substance surrounding the axons that extend from nerve cells.
In the new study in mice, researchers at NYU Langone Medical Center found that nerve cells dedicated to hearing also rely on surrounding context to properly interpret and react to familiar sounds.
Froemke says his team's latest findings reveal that while mammals recognize sounds in the auditory cortex of their brains, the signaling levels of nerve cells in this brain region are simultaneously being strengthened or weakened in response to surrounding context.
Neuroscientists have long believed that scar tissue formed by glial cells — the cells that surround neurons in the central nervous system — impedes damaged nerve cells from regrowing after a brain or spinal cord injury.
When nerve cells are injured so severely, surrounding cells also die off in the hours after the trauma.
There are two categories of CMT: those caused by the loss of axons in the peripheral nerves (CMT2) and those characterized by a malfunction in the Schwann cells that make up the myelin sheath, the protective coating that surrounds the nerve fibers and allows them to conduct nerve signals at high speeds (CMT1).
May 10, 2006 Selectively blocking inflammatory signals may protect mice from MS A new way to preserve the cells that surround and protect nerves could lead to new treatments for demyelinating diseases such as multiple sclerosis, a research team reports in the May 10, 2006 issue of the Journal of Neuroscience.
But the precise function of PMP22, a major component of the myelin sheath that surrounds and insulates peripheral nerve cell axons, has been unclear.
When a nerve cell is activated, it sends an electrical impulse down its axon to the terminal, which stimulates a vesicle within the terminal to migrate to the terminal's surrounding membrane.
The microglia then «summon» peripheral immune cells from other parts of the body, and these cells proceed to attack the protective myelin sheaths that surround the axons — or nerve fibers — in the brain.
This computer rendering shows the skeletonized structure of heterochromatin (red represents a thin region while white represents a thick region), a tightly packed form of DNA, surrounding another form of DNA - carrying material known as euchromatin (dark blue represents a thin region and yellow represent the thickest) in a mouse's mature nerve cell.
In a proof - of - principle study published in the journal Cell Stem Cell, the researchers report that defects in the regeneration of the myelin sheaths surrounding nerves, which are lost in diseases such as multiple sclerosis may be at least partially corrected following exposure of an old animal to the circulatory system of a young animal.
LA JOLLA, CA — Multiple sclerosis, a debilitating neurological disease, is triggered by self - reactive T cells that successfully infiltrate the brain and spinal cord where they launch an aggressive autoimmune attack against myelin, the fatty substance that surrounds and insulates nerve fibers.
Fat plays a big role in the construction of cell membranes and the sheaths surround nerves, while also being vital for blood clotting and inflammation.
It also acts as anti-inflammatory and antioxidant, and because it is both fat - soluble and water - soluble, has a special affinity for nerve and brain cells, which are surrounded by fatty sheaths.
This three - dimensional complex matrix threads itself throughout our body, surrounding our muscles, organs, nerves, bones, blood vessels and even our cells.
Apart from being a valuable source of energy, it also helps you absorb certain vitamins and minerals, it's needed to build cell membranes and the sheaths surrounding nerves, it's essential to blood clotting, it's required for the manufacture of certain hormones and it's vital to the health of your skin, joints, muscles, and much more.
