This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preeclampsia (PE) is characterized by endothelial cell (EC) dysfunction, loss of vasodilatory capacity, and loss of EC integrity. In a healthy pregnancy, there is a 'normal' increase in inflammatory factors, including TNF-[alpha]. TNF-[alpha] abundance increases beyond compensatory limits in PE. The first aim examined the requirement of SRC (using inhibitors PP2, PP3, SRC-I1, Dasatinib*, Saracatinib*, *denotes clinical inhibitor), MEK (using inhibitors U0126, PD98059, PD0325901), and P38MAPK (using inhibitors SB203580, BIRB0796) in maintaining resistance (a hallmark of EC integrity) in P-UAECs via ECIS in the absence and presence of TNF-[alpha]. Our results showed that these inhibitors (and combinations) have differential responses in the absence and presence of TNF-[alpha]. While some inhibitors (and combinations) were stimulatory in the absence, none were able to provide complete or full protection in the presence of TNF-[alpha]-mediated destruction. We concluded the resistance of the P-UAEC monolayer is regulated by SRC, MEK, and P38MAPK. The second aim was to identify the effect of other inflammatory mediators, including interleukin 1[beta] (IL-1[beta]), interleukin 6 (IL-6), and interleukin 8 (IL-8) in the absence and presence of TNF-[alpha] (using P-UAECs via ECIS). In addition, we attempted to discern the effects of GP130 and the downstream signaling pathway JAK (using inhibitor AG490) and SRC (using inhibitor PP2) on EC integrity in the absence and presence of TNF-[alpha], IL-1[beta], or TNF+IL-1[beta]. In the absence of TNF-[alpha] several inhibitors (or combinations) increased resistances above control. However, none of the agents tested (alone or in combination) could prevent or provide full rescue of P-UAEC integrity from the effects of TNF-[alpha] alone or the IL-1[beta]+TNF-[alpha] combination. We conclude that while IL-1[beta] and TNF-[alpha] share some signaling pathways, they are clearly under distinct mechanisms of control. In the third and final aim, we examined if P-UAECs undergo cell surface changes (a process known as immune modulation) in response to long-term exposure (20hrs) to different cytokines TNF-[alpha] , IL-1[beta], or IFN-[gamma] and identify if there were subpopulations of cells (using multiparameter flow cytometry experiments). The novel discovery of this collection of work is that PUAEC subpopulations were formed and changes of these populations depend upon the type of cytokine treatment. Immune modulation is indeed at play in regulating endothelial subpopulations, damage, and, therefore, the pathogenesis of preeclampsia.

Download or read book The Endothelium written by Michel Félétou and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Download or read book Deciphering new molecular mechanisms of mast cell activation written by Ulrich Blank and published by Frontiers E-books. This book was released on 2014-03-20 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mast cells are tissue-localized cells that play an important role in immunity and inflammation. Following an offensive event they act as cellular sensors that via the activation of cell surface receptors launch a cellular response culminating in the release of a whole set of inflammatory mediators and products. This response is initially destined to restore tissue homeostasis, but in case of chronic injury or deregulation also promotes pathology. To further understand the action of mast cells in their environmental context it is necessary to decipher the molecular mechanisms of their activation as well as the ensuing cellular responses. This will allow identification of new strategies to promote their beneficial actions or, at the contrary, to interfere with their pathological consequences. While in the past many studies have focused on responses engaged by high affinity IgE receptor because of its implication in the allergic response, it has become clear that mast cells can be activated by multiple types of receptors initiating an intense molecular crosstalk between receptors and signaling pathways that can either synergize, antagonize and in some cases produce new types of responses. Mast cells can indeed react with an astounding diverse array of cellular responses that sometimes are engaged selectively. This Research Topic will focus on selected articles that shed some new light on the molecular mechanisms of mast cell activation, the possible crosstalk between signaling pathways and the ensuing cellular responses that allow mast cells to act as cellular sensors in tissues.

Download or read book Prediction of Maternal and Fetal Syndrome of Preeclampsia written by Nidhi Sharma and published by BoD – Books on Demand. This book was released on 2019-10-02 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The clinical syndrome of preeclampsia is due to vasospasm, endothelial dysfunction, and altered red cell zeta potential. It is a culmination of multiple etiologies and pathophysiologies modified by epigenetics and the human immune system. Since the etiology and pathogenesis of preeclampsia are segregated and multifactorial, there is no single clinical, biophysical, or biochemical marker that can predict all types of this condition. This book provides a set of tentative specific prediction markers that can be used to identify different subtypes of preeclampsia, classify pathogenesis, categorize treatment, and identify early signs of complications.
Download or read book Vascular Endothelium written by John D. Catravas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph contains the proceedings from the Advanced Study Institute on "Vascular Endothelium: Physiological Basis of Clinical Problems" which took place in Corfu, Greece in June 1990. The meeting consisted of twenty-eight lectures, most of them adapted as full length papers in this volume, as well as numerous short oral and poster communications which are abstracted and also included in alphabetical order (pages 239-302). There were ninety-six participants from ten NATO and four other European countries. The meeting was the second in as many years dealing with a specific subject in Endothelial Cell biology. Following the 1988 discussion on "Receptors and Transduction Mechanisms", the present ASI recognized and tried to deal with the increasing overlap in interest between basic scientists studying endothelial cell functions and clinicians facing problems of known or suspected endothelial pathological involvement. As with any similar effort, we opted to be selective, rather than fail by trying to be inclusive, in the subjects covered. We chose to discuss diseases, such as atherosclerosis, sepsis, ARDS and stroke, based on their relevance to endothelial cell function and urgent need for new insights into their pathogenesis and treatment. Similarly, we examined endothelial cell functions by considering their relevance to disease and their potential for elucidating important pathologies. Obviously, some areas were covered superficially or not at all; this should not distract from their importance, but rather reflect on the constraints of time and -not at all negligibly -the bias of the organizing committee.
