text: The leukotriene (LT) receptors are G protein-coupled receptors that bind and are activated by the leukotrienes. They include the following proteins:
  * Leukotriene B4 receptors (BLTRs) – bind to and are activated by LTB4:
  ** BLT (Leukotriene B receptor 1)  – 
  ** BLT (Leukotriene B receptor 2)  – 
  * Cysteinyl leukotriene receptors (CysLTRs) – bind to and are activated by LTC4, LTD4, and LTE4:
  ** CysLT (Cysteinyl leukotriene receptor 1) – 
  ** CysLT (Cysteinyl leukotriene receptor 2) – 
  The recently elucidated CysLT, represented by GPR99/OXGR1, may constitute a third CysLTR.
