What Does The Sodium Potassium Pump Do – Electrical potential is carried by ions present throughout the membrane of all body cells. Some cells, such as neuronal cells, cardiac muscle, etc., are efficient. The property is called excitability, led by a stimulus that has a potential greater than the threshold potential.

An action potential is a change in electrical potential/voltage across the membrane of cells that causes impulses to be sent to their membrane.

What Does The Sodium Potassium Pump Do

The period in which the new stimulus fails to increase the ability to act is the refractory period. Even a strong stimulus can not produce nerve impulses, and this period lasts for two milliseconds.

Membrane Potential (resting Membrane Potential) (article)

Nerve impulses originate in the neuron body and propagate through the axon. Most of the axons are protected by myelin sheaths produced by glial cells. The protective sheath helps in the insulation of the axonal membrane. These myelinated structures are oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Between the myelinated segments, there are gaps called the nodes of Ranvier. The impulse transmission occurs between the nodes and is called saltatory conduction.

Synapses are the difference between two neurons. The neuron sending the signal is called presynaptic neuron, while the one receiving it is called postsynaptic neuron.

Depending on the type of signal allowed, synapses can be chemical or electrical. Chemical synapses are mediated by chemicals called neurotransmitters in a unidirectional way. Neurotransmitters are contained in synaptic vesicles released in the synaptic cleft and bind to receptor molecules on the postsynaptic membrane.

Ions mediate electrical synapses in a bidirectional way. The electrical changes in the presynaptic membrane induce a voltage change in the postsynaptic membrane through special structures called gap junctions. The rate of flow of impulses, in this case, is much faster.

Activation Of The Sodium Potassium Pump Contributes To Insulin Induced Vasodilation In Humans

Deepa Pudasaini is a graduate student of MSc Microbiology studying at Central Department of Microbiology, Tribhuvan University, Kathmandu, Nepal. He is interested in research related to microbiology and immunology. Researchers with the Marshall University Joan C. Edwards School of Medicine (SOM) and the Marshall University Institute for Interdisciplinary Research (MIIR) have identified a technique to block signals from cell phones. sodium-potassium pump amplifies oxidants (reactive oxygen species). These oxidants cause obesity and metabolic syndrome.

Joseph I. Shapiro, MD, dean of the school of medicine and senior author, said the study was truly collaborative.

“I am very proud of this project, as the research was developed, conducted and analyzed entirely at Marshall University,” said Shapiro. “This work is based on two important things. We work on a peptide, pNaKtide, which is derived from the new ideas developed by Marshall’s MIIR director, Dr. Zijian Xie. In particular, Dr Xie showed that, in addition to its positive role as an ion transporter, the sodium pump also regulates signal transduction and oxidant amplification. We also used Marshall’s SOM vice research supervisor, Dr. Nader Abraham, who found an important role for oxidant stress in adipocytes in development. The research, which addresses the main problem in the Appalachian people who our work, has been done by our research staff at Marshall University.”

First author Komal Sodhi, MD, associate professor of surgery and pharmacology at Marshall, said the study examined a peptide (pNaKtide) designed to block the sodium potassium Na/K-ATPase signaling cascade, which changing the phenotype of adipocytes (fat cells) in a cell culture system.

“We found this reduced the development of obesity and metabolic syndrome in mice that were fed high-fat diets,” Sodhi said. “Studies support this idea and suggest that if this is confirmed in humans, Na/K-ATPase will eventually be a therapeutic target for the treatment of obesity and metabolic diseases. syndrome, which especially affects West Virginia where more. -Three of the population is now obese.”

Shapiro said that while there are many years of work ahead of time for scientists to determine the impact on humans, they believe they have hit on a viable strategy to treat obesity and metabolic syndrome. .

“The bottom line is that we have identified a new mechanism to deal with oxidant stress and, through this mechanism, treat obesity,” Shapiro said. “Our work opens new targets for intervention in this disease as well as other diseases caused by oxidant stress.”

In addition to Shapiro and Sodhi, Marshall’s research team includes Kyle Maxwell; Yanling Yan, Ph.D. Jiang Liu, M.D., Ph.D.; Muhammad A. Chaudhry, M.A.; Morgan Getty; Zijian Xie, Ph.D. and Nader G. Abraham, Ph.D.

The men participated in a competition that tested their brute strength against other teams. The Humvee weighs about 13 thousand pounds (about 5,897 kilograms), so it takes every ounce of strength they can muster to keep it up the hill against the force of gravity.

The concentration gradient. This type of transport is called active transport. The energy for transport comes from the energy carrier molecule called

(Adenosine triphosphate). Transport may also require proteins called pumps, which are inserted into the plasma membrane. Two types of transport are membrane pumps (such as the sodium-potassium pump) and vesicle transport.
