Cysteinyl leukotriene receptor 2

Cysteinyl leukotriene receptor 2 (CysLTR2) is a protein that in humans is encoded by the CYSLTR2 gene. It is a member of the G protein-coupled receptor family and plays a crucial role in mediating the effects of leukotrienes in the body.

Function[edit | edit source]

CysLTR2 is a receptor for cysteinyl leukotrienes, which are a group of biologically active lipids that have been implicated in various types of inflammatory responses including asthma and allergy. The receptor is expressed in various tissues, including the lung, spleen, heart, and adrenal gland. It is also found in the smooth muscle cells of the airway, where it mediates the contraction and proliferation of these cells.

Clinical significance[edit | edit source]

Alterations in the function or expression of CysLTR2 have been associated with various pathological conditions. For example, increased expression of this receptor has been observed in patients with asthma, suggesting a potential role in the pathogenesis of this disease. Furthermore, mutations in the CYSLTR2 gene have been linked to a rare form of urticaria, a skin condition characterized by the development of itchy, red welts.

Research[edit | edit source]

Research into the function and potential therapeutic targeting of CysLTR2 is ongoing. Some studies suggest that antagonists of this receptor may have potential as novel treatments for conditions such as asthma and allergic rhinitis.
