Disease relevance of Cysltr1


High impact information on Cysltr1

  • This and other previously reported proinflammatory effects of LTD4 may contribute significantly to its overall influential role in the pathophysiology of asthma, and may underlie the therapeutic benefit of CysLT receptor antagonists, such as pranlukast, in this disorder [4].
  • The leukotriene receptor B4 and the cysteinyl leukotriene receptor type 1 were selectively expressed in the glomerulus, whereas cysteinyl receptor type 2 was not found in any nephron segment [5].
  • In the ischemic core, cysteinyl leukotriene receptor 1 was primarily localized in neurons 24 h, and in macrophage/microglia 14 days after reperfusion; while in the boundary zone it was localized in proliferated astrocytes 14 days after reperfusion [1].
  • Inclusion of the selective 5-lipoxygenase inhibitor AA-861 or the cysteinyl leukotriene receptor antagonist MK-571 significantly reduced the vasoconstrictor responses to angiotensin II but not to endothelin-1 and potassium chloride [6].
  • The present study aimed to investigate the possible protective effect of montelukast, a selective antagonist of cysteinyl leukotriene receptor 1 (leukotriene CysLT1), against Escherichia coli-induced oxidative injury and scarring in renal tissue [7].

Biological context of Cysltr1

  • A selective CysLT(1) receptor antagonist montelukast did not affect OGD-induced apoptosis; while non-selective CysLT receptor antagonist Bay u9773 inhibited OGD-induced apoptosis, especially in CysLT(2) receptor over-expressing cells [8].

Anatomical context of Cysltr1

  • The effects of BAY u9773 (6(R)-(4'-carboxyphenylthio)-5(S)-hydroxy-7(E),9(E), 11(Z),14(Z)-eicosatetraenoic acid), a cysteinyl-leukotriene analogue, were investigated on a variety of smooth muscle preparations in order to determine its profile as a cysteinyl-leukotriene receptor antagonist [9].

Associations of Cysltr1 with chemical compounds


Analytical, diagnostic and therapeutic context of Cysltr1

  • We found that cysteinyl leukotriene receptor 1 mRNA expression was up-regulated in the ischemic core both 3-12 h and 7-14 days, and in the boundary zone 7-14 days after reperfusion [1].
