“…Whilst other nuclear receptor pathways for example NF-B have been shown to exert some control of inflammatory processes (Chen al., 2003), only calcineurin inhibitors have proved effective in suppressing organ rejection. Cyclosporine and FK-506 have since found success in a wide range of therapeutic contexts including rheumatoid arthritis, systemic lupus erythematosus, eczema and psoriasis so confirming the importance of calcineurin as an immunological drug target (Wells et al, 2000;Al-Daraji et al, 2002;Reynolds and Al-Daraji, 2002;Lewis-Jones and Mugglestone, 2007;Lampropoulos and D'Cruz, 2010).…”
