Sentences with phrase «when endothelial cells»

Thus, I hypothesize that the intestinal inflammation and low - grade fever are due to an overactive immune system, necessitated by the fact that pathogens have easier access when the endothelial cells are deficient in cholesterol sulfate.

«When these endothelial cells are delivered in a gel, they are protected.

Amongst these were genes that were lost when endothelial cells were removed from the body and cultured in the laboratory, which potentially explains the previous failure to identify them.

When endothelial cells were restored, blood cells developed.

Not exact matches

Sydenham chorea was like rheumatic fever of the brain, thought to occur when rheumatic fever progresses and strep antibodies (emboldened by fever) breaches the blood - brain barrier (BBB), the tight wall of endothelial cells ordinarily there to protect the brain from the outside world.

However, when the researchers knocked out SIRT1 in endothelial cells of 10 - month - old mice, then put them on a four - week treadmill running program, they found that the exercise did not produce the same gains seen in normal 10 - month - old mice on the same training plan.

In earlier studies involving animal models and human cancer cell lines, researchers found that breast cancer spreads when three specific cells are in direct contact: an endothelial cell (a type of cell that lines the blood vessels), a perivascular macrophage (a type of immune cell found near blood vessels), and a tumor cell that produces high levels of Mena, a protein that enhances a cancer cell's ability to spread.

When zebrafish with the green fluorescing endothelial gene matured, the researchers observed green FGPs on the surface of the fish's brains — confirming that these cells arose from endothelial tissue.

«ECPR and a factor in the blood called protein C act as a «brake» on blood coagulation and endothelial cell inflammation and also enhance the viability and integrity of blood vessels, but when the malaria parasites use PfEMP1 to bind EPCR, they may interfere with the normal function of EPCR, and thus the binding can be the catalyst for the violent reaction,» he explains.

Now, a multidisciplinary research team led by David Eckmann, MD, PhD, Horatio C. Wood Professor of Anesthesiology and Critical Care at the Perelman School of Medicine at the University of Pennsylvania and professor of Bioengineering in Penn's School of Engineering and Applied Science, has found that when delivered by a microscopic transporter called a nanocarrier, steroids can access the hard - to - reach lung endothelial cells that need it most and are successful at preventing inflammation in mice.

The force of that blood flow helps keep the cells that line the blood vessels, called endothelial cells, healthy; when blood flow is disrupted, such as during surgical procedures or a stroke, the vessels start to leak, which can cause a host of inflammatory responses that lead to cell damage and disease.

In addition, when these transcription factors lose their function, terminal differentiation into the vascular endothelium (completion of differentiation) is completely suppressed, and genes that are key to differentiation into vascular endothelial cells as well as transcription factors that maintain the undifferentiated state are adversely induced.

The endothelial cells have a receptor for transferrin that acts like a gatekeeper: When transferrin binds to a receptor on the blood side of the barrier, the endothelial cell transports it (and its iron cargo) to the other side and spits it out into the brain.

When a new vessel is needed, the endothelial cells direct the process by allowing the recruitment of blood cells required for neovascularization, commonly called angiogenesis.

When primary cultures from these mice are stimulated with proinflammatory cytokines, the endothelial cell fraction responds by up - regulating the inducible endothelial cell adhesion molecules, E-selectin and VCAM - 1.

Each of the endothelial cell lines demonstrated an ability to orient into capillary - like structures when placed onto a Matrigel surface (Fig. 5A) ⇓.

When human corneal endothelial cells were stimulated with EGF following wounding, staining also appeared in the periphery (not shown).

Evidence suggests that cells from this area migrate (perhaps as transient amplifying cells) to the endothelial periphery and, perhaps, to wounded areas of the corneal endothelium when needed.

The researchers found that, when stimulated by insulin, diabetic fibroblasts produced less of the VEGF (vascular endothelial growth factor) signaling protein, a key player in boosting the growth of blood vessel cells, than normal fibroblasts did.

Three recent experimental studies focused on low consumption / exposure.949596 In one study, 29 smokers each consumed a single cigarette, immediately after which they had a significant decrease in blood vessel output power and significant increase in blood vessel ageing level and remaining blood volume 25 minutes later, as markers of atherosclerosis.94 In another study, human coronary artery endothelial cells were exposed to the smoke equivalent to one cigarette, which led to activation of oxidant stress sensing transcription factor NFR2 and up - regulation of cytochrome p450, considered to have a role in the development of heart disease.95 These effects were not seen when heart cells were exposed to the vapour from one e - cigarette.95 A study exposed adult mice to low intensity tobacco smoke (two cigarettes) for one to two months and found adverse histopathological effects on brain cells.96

Morphologically similar endothelial cells have been observed when they were differentiated into mature endothelial (CD133 --RRB- by culturing them in high density culture from low density culture at different passages.

Bodybuilding.com says that «When a man becomes sexually stimulated either through physical contact or other sensory stimuli, a signal is sent from the brain to endothelial cells in the penis to release nitric oxide (NO).»
