Cyclophilin A (CypA), a well-recognized receptor for anti-inflammatory drug cyclosporine A (CsA) is a ubiquitous and multifunctional protein. Beside the diverse intracellular functions, CypA is secreted against inflammatory stimuli, where it activates and attracts leukocytes via CD147 to the stimulus site. Interestingly, it synergizes with other factors to induce leukocyte migration in different animals. However, the silencing and inhibition of CypA or CD147 inhibits leukocytes chemotaxis and inflammation. This review focuses on the advances made in understanding the mechanism of CypA-dependent leukocytes chemotaxis and hence, recognition of this factor as a possible therapeutic target in inflammatory diseases.
Keywords: cyclosporine A; inflammation; migration.
