AGR2
AGR2: A Critical Regulator of Inflammation and Disease
Description:
AGR2 (Anterior Gradient 2) is a key protein involved in inflammation and the regulation of the immune response. It belongs to the family of G protein-coupled receptors (GPCRs) and is predominantly expressed in immune cells, including neutrophils, macrophages, and dendritic cells. AGR2 acts as a signaling receptor, binding to specific ligands to initiate cellular responses.
Associated Diseases:
Defects in AGR2 function have been implicated in various diseases, including:
- Inflammatory bowel disease: AGR2 is essential for maintaining intestinal homeostasis. Its deficiency in mice leads to severe colitis.
- Rheumatoid arthritis: AGR2 is overexpressed in synovial tissues of rheumatoid arthritis patients and contributes to joint inflammation and destruction.
- Asthma: AGR2 regulates airway inflammation and hyperresponsiveness in asthma.
- Cardiovascular disease: AGR2 is involved in the regulation of blood pressure and inflammation in the heart.
- Cancer: AGR2 expression is associated with tumor progression and metastasis in certain types of cancer.
Did you Know ?
Studies have found that individuals with AGR2 polymorphisms have an increased risk of inflammatory bowel disease. Carriers of a specific genetic variant in AGR2 have a 2.5-fold higher risk of developing Crohn‘s disease.
