Regulation of cell migration and inflammation by ceramide 1-phosphate

Ceramide 1-phosphate (C1P) is a phosphosphingolipid with potent biological activities. It promotes cell growth and survival, and is a key regulator of cell migration. Both C1P and the enzyme that catalyzes its biosynthesis, ceramide kinase, are implicated in inflammatory responses. Although C1P has pro-inflammatory properties, it reduces pulmonary emphysema and exerts anti-inflammatory actions in the lung. Synthetic C1P analogs may be promising tools to treat lung inflammation.
