48. Sjogren's syndrome is an autoimmune disorder where the tear duct glands are no longer producing tears so the patient experiences dry eye. One of the treatments for Sjogren's syndrome is cyclosporine, an immunosuppressive information, cyclosporine agent. Based on this a. activates histamine production b. directly deactivates neutrophils c. activates leukocidin activity d. indirectly deactivates Tc cells e. activate macrophage activity
