Leukotriene B4 receptor

The Leukotriene B4 receptor (LTB4 receptor) is a G protein-coupled receptor (GPCR) that binds to leukotriene B4 (LTB4), a potent inflammatory mediator. This receptor plays a crucial role in the immune system by mediating the effects of LTB4, which include the recruitment and activation of leukocytes.

Structure[edit | edit source]

The LTB4 receptor is a member of the G protein-coupled receptor family, characterized by seven transmembrane domains. There are two main subtypes of the LTB4 receptor: BLT1 and BLT2. BLT1 has a high affinity for LTB4, while BLT2 has a lower affinity but can also bind other ligands.

Function[edit | edit source]

The primary function of the LTB4 receptor is to mediate the biological effects of LTB4. Upon binding to LTB4, the receptor activates intracellular signaling pathways that lead to various immune responses, including:

Role in Disease[edit | edit source]

The LTB4 receptor is implicated in several inflammatory diseases due to its role in leukocyte recruitment and activation. Conditions associated with dysregulated LTB4 receptor activity include:

Pharmacology[edit | edit source]

Given its role in inflammation, the LTB4 receptor is a target for therapeutic intervention. Antagonists of the LTB4 receptor are being investigated for their potential to treat inflammatory diseases by inhibiting the receptor's activity and reducing leukocyte recruitment and activation.
