Contributions of mast cells and vasoactive products, leukotrienes and chymase, to dengue virus-induced vascular leakage

open access: yeseLife, 2013
Dengue Virus (DENV), a flavivirus spread by mosquito vectors, can cause vascular leakage and hemorrhaging. However, the processes that underlie increased vascular permeability and pathological plasma leakage during viral hemorrhagic fevers are largely ...

Integrated genomic, transcriptomic, and epigenetic analyses identify a leukotriene synthesis-related M2 macrophage gene signature that predicts prognosis and treatment vulnerability in gliomas

open access: yesFrontiers in Immunology, 2022
The pathological implications of tumor-associated macrophages in the glioma microenvironment have been highlighted, while there lacks a gene signature to characterize the functional status and clinical implications of these cells.

NSAIDs and Acute Pancreatitis: A Systematic Review

open access: yesPharmaceuticals, 2010
The resulting pain is the main symptom of acute pancreatitis and it should be alleviated as soon as possible. NSAIDs are the first line therapy for pain and they are generally administered to acute pancreatitis patients upon admission to the hospital. In

Crosstalk between ORMDL3, serine palmitoyltransferase, and 5-lipoxygenase in the sphingolipid and eicosanoid metabolic pathways

open access: yesJournal of Lipid Research, 2021
Leukotrienes (LTs) and sphingolipids are critical lipid mediators participating in numerous cellular signal transduction events and developing various disorders, such as bronchial hyperactivity leading to asthma. Enzymatic reactions initiating production

気管支喘息患者における白血球ロイコトリエン産生能に対する不飽和脂肪酸食の効果に影響する因子 [PDF]

open access: yes, 1999
Dietary supplementation with perilla seed oil, a vegetable oil rich in α -lin- olenic acid, inhibits the generation of leukotrienes(LTs) by leucocytes in patients with bronchial asthma. We examined the factors that affect the suppression of LT generation

Differential impact of 5-lipoxygenase-activating protein antagonists on the biosynthesis of leukotrienes and of specialized pro-resolving mediators

open access: yesFrontiers in Pharmacology, 2023
Lipoxygenases (LOX) transform arachidonic acid (AA, C20:4) and docosahexaenoic acid (DHA, C22:6) into bioactive lipid mediators (LMs) that comprise not only pro-inflammatory leukotrienes (LTs) but also the specialized pro-resolving mediators (SPMs) that ...

Assay of Leukotrienes

open access: yes, 1983
The leukotrienes and the related hydroxy acids constitute a chemically and biologically rather heterogenous group of compounds. Thus, the assay methods employed for their detection and quantification by necessity differ considerably, depending on what ...

Pulmonary and Cardiovascular Pharmacology of Leukotrienes

open access: yes, 1983
Leukotrienes rapidly gained widespread recognition as substan­ces of potentially great impact when slow reacting substance of ana­phylaxis (SRS-A) was shown to be included in this newly discovered family of arachidonic acid derivatives (Murphy et al ...

Post-transcriptional regulation of 5-lipoxygenase mRNA expression via alternative splicing and nonsense-mediated mRNA decay [PDF]

open access: yes, 2012
5-Lipoxygenase (5-LO) catalyzes the two initial steps in the biosynthesis of leukotrienes (LT), a group of inflammatory lipid mediators derived from arachidonic acid.

Biosynthesis and Metabolism of Leukotrienes

open access: yes, 1983
Leukotriene biosynthesis has until today been detected in several biological systems (Table I) using different kinds of stimuli: ionophore A23187, the bacterial peptide f-Met-Leu-Phe (fMLP), antigen-antibody interactions, phagocytic stimuli, and, not to ...
