Sentences with phrase «levels of endothelial cell»
Established cell lines exhibited several inherent endothelial properties, including the expression of constitutive and inducible levels of endothelial cell adhesion molecules E-selectin, intercellular adhesion molecule - 1, and vascular cell adhesion molecule - 1, internalization of acetylated low - density lipoprotein, and formation of loop structures on Matrigel surfaces.

Specifically, the study — reported online in The Journal of Infectious Diseases — shows that E. coli K1 modulates the protein peroxisome proliferator - activated receptor - gamma (PPAR - γ) and glucose transporter - 1 (GLUT - 1) levels at the blood - brain barrier in human brain microvascular endothelial cells.
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.
In contrast, lymphocytes in both types of endothelial cell grafts expressed higher levels of genes known to be involved in dampening the immune response and inducing self - tolerance.
This experiment uses quantitative PCR to detect the expression level of POSTN in CD34 + / CD31 − pulmonary fibroblasts, CD31 + endothelial cells, and CD45 + immune cells isolated from lungs of mice with macrometastases, which is a replication of the experiment reported in Figure 2H.
The constitutive expression of these endothelial cell adhesion molecules was very similar for most of the lines derived from different organs, i.e., very low expression levels of E-selectin and VCAM - 1 and more pronounced expression of ICAM - 1.
The highest level of expression was found in heart and bladder endothelial cells.
As expected, all of the endothelial cell lines showed diminished constitutive expression of E-selectin (data not shown) and VCAM - 1 (Fig. 4C) ⇓ in comparison with surface levels of ICAM - 1 (Fig. 4B) ⇓.
Endothelial cells line the inside of all blood vessels and regulate inflammation, blood clotting following injury and blood pressure levels.
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
EDR activity involves the release of endothelial nitric oxide (NO) release and subsequent increase in cyclic guanosine monophosphate (GMP) levels in the vascular smooth muscle cells ultimately increasing vasodilation and blood flow.
Regardless of weight, women with PCOS have been shown to have higher levels of inflammatory markers such as increases in C - reactive protein (CRP), pro-inflammatory cytokines and chemokines, white blood cell count, oxidative stress, and various markers of endothelial inflammation.
At the cellular level this changes the tension on the filaments of the endothelial cells of the initial lymphatic capillaries, facilitating their opening and closing.
