Sentences with phrase «receptors on nerve cells»

And when lectins take up residence on insulin receptors on nerve cells, your neurons never get the energy that they need, and so they continually send a message that you're hungry in hopes of getting more fuel.

The nanoparticle's shape gives it more surface area than spherical particles, improving the surface protein's ability to bind with receptors on nerve cells that serve as a gateway to the nervous system.

Now, researchers have determined that an unstable chemical in crushed, raw garlic titillates two receptors on nerve cells that trigger pain — the same receptors that are stung by hot peppers and menthol.

The social environment seems to affect the receptors on nerve cells that respond to neurotransmitters like serotonin, which in turn changes how alcohol affects nerves.

Maged Harraz, Ph.D., a research associate and the first author of the newly published research paper, says the researchers already knew that ketamine interacts with excitatory NMDA receptors on nerve cells in the brain to block their activity.

Not exact matches

In the current study, Frank Longo, MD, PhD, and others at Stanford University, tested LM22A - 4, a drug that specifically binds to and activates the BDNF receptor TrkB on nerve cells, in mice that model the disorder.

«What we think happens is that the bacteria activate immune cells, which release chemicals called cytokines that then act on receptors on the sensory nerves to increase their activity,» he says.

In a report on the study, published Feb. 5 in Nature Neuroscience, researchers say the biochemical receptor, known as a G protein - coupled receptor, was present on nerve cells in the lower respiratory tracts of lab mice.

Using fluorescent antibodies designed specifically to light up the receptor in mice, the investigators observed it on vagus nerves, which serve as a main biochemical connection between airway cells and the brain.

«Our data clearly showed that one of the protein receptors on white blood cells called CXCR3 brings white blood cells to the optic nerve in response to production of its binding partner CXCL10 by damaged nerve tissue,» said Zhang.

Yonju Ha, a lead author of this article, said that further studies on this receptor and its role in white blood cell recruitment following tissue injury may aid in the development of new interventions for diseases associated with nerve injury, such as TON, stroke, diabetic retinopathy and glaucoma.

When chemical phosphate groups are added to the receptors, they move from the cytoplasm and cluster on the edges of nerve cells along synapses — the spaces between nerve cells where messages transmit from one cell to another.

a) The Eye in your Thigh: a patch of skin cells on the leg that can distinguish between bright and dark conditions, perhaps to help regulate the body clock b) The Ear in your Rear: nerves in the buttocks attuned to infrasound vibrations of between 10 and 25 hertz, perhaps to warn of approaching predators or thunderstorms c) The Nose in your Toes: scent - detecting sebaceous glands on the feet whose purpose is unclear d) The Tongue in your Lung: taste - bud - like receptors that detect bitter substances and dilate or restrict the airways accordingly

The impulses cause glutamate (one of the brain's main neurotransmitters) to pop out of one nerve cell and travel across the synapse to activate the next by binding to its receptors, chemically active signaling stations on the cell surface.

These designer proteins bind tightly to CGRP molecules or their receptors on trigeminal nerve cells, preventing cell activation.

In a brain slice, Olivia Masseck measures the activity of nerve cells in which she switches on their receptors using light stimulation.

As a result, they are too broad: They affect more than one type of receptor, on more than one kind of nerve cell, in more than one part of the brain.

Both endorphins and opioids latch on to proteins called opioid receptors on the surface of nerve cells.

The 5 - HT released by type III cells could also activate 5 - HT3 receptors on afferent nerve fibers.

Herein, we test whether 5 - HT released by taste cells plays a role in the transmission of taste information by activation of 5 - HT3 receptors on afferent nerve fibers.

Those naturally produced opioids, and the opioid drugs that imitate them, inhibit pain by acting on three kinds of opioid receptors — mu, kappa and delta — that are found on the outside of nerve cells in the brain, spinal cord, digestive tract and elsewhere.

Although Wnts were better known because of their role as morphogens — proteins that pattern bodily structures and determine cell fates — Zou recently showed how members of the Wnt family served to guide pathfinding axons up and down the spinal cord by attracting or repelling receptors on the growth cones of sensory or motor nerves.

They include Fridolin Sulser, who helped develop tricyclic antidepressants, Elaine Sanders - Bush, whose lab made several important discoveries about the neurotransmitter serotonin and its receptors, and Randy Blakely, nationally known for his work on transporters, which sweep up neurotransmitter from the synaptic gap between nerve cells.
