Impaired Glutathione Synthesis in Neurodegeneration
Glutathione (GSH) was discovered in yeast cells in 1888. Studies of GSH in mammalian cells before the 1980s focused exclusively on its function for the detoxication of xenobiotics or for drug metabolism in the liver, in which GSH is present at its highest concentration in the body. Increasing evidence has demonstrated other important roles of GSH in the brain, not only for the detoxication of x...
متن کاملCysteinyl Leukotrienes and Their Receptors; Emerging Concepts
Cysteinyl leukotrienes (cys-LTs) are potent mediators of inflammation derived from arachidonic acid through the 5-lipoxygenase/leukotriene C4 synthase pathway. The derivation of their chemical structures and identification of their pharmacologic properties predated the cloning of their classical receptors and the development of drugs that modify their synthesis and actions. Recent studies have ...
متن کاملSynthesis and metabolism of leukotrienes in -glutamyl transpeptidase deficiency
Leukotrienes (LTs) are active lipid mediators derived in the 5-lipoxygenase pathway. LTC 4 , the primary cysteinyl LT, is cleaved by -glutamyl transpeptidase (GGT), resulting in LTD 4 . We studied the synthesis and metabolism of LTs in three patients with GGT deficiency. LTs were analyzed in urine, plasma, and monocytes after HPLC separation by enzyme immunoassays, radioactivity detection, and ...
متن کاملIncreased generation of cysteinyl leukotrienes in Kawasaki disease.
Endogenous cysteinyl leukotriene synthesis was assessed in 10 patients with Kawasaki disease and 10 healthy controls by measuring excretion of leukotriene E4 (LTE4) in urine. LTE4 was increased more than fivefold in patients with Kawasaki disease compared with controls (median (range) 55.3 (31.8-120.6) v 10.2 (7.1-14.9) nmol/mol creatinine); this suggests that cysteinyl leukotrienes are involve...
متن کاملAdipokines and Cysteinyl Leukotrienes in the Pathogenesis of Asthma
Background. The prevalence of obesity has increased dramatically over the last decades, and its association with asthma is being increasingly recognized. Aims. Our hypothesis is that increased leptin and decreased adiponectin levels in obese subjects play a direct role in regulating inflammation in asthmatics. We wanted to examine the hypothesis that cysteinyl leukotrienes (cys-LT), inflammator...
