| Title | Bench to bedside of CTLA-4: a novel immuno-therapeutic agent for inflammatory disorders. | | Author(s) | Sakthivel P | | Institution | Rheumatology Unit, Center for Molecular Medicine, Karolinska Institute, Stockholm, Sweden. priya.sakthivel@ki.se | | Source | Recent Pat Inflamm Allergy Drug Discov 2009; 3(2):84-95. | | Abstract | Co-stimulatory molecules are antigen-independent generators of secondary signals which aid in maintaining the homeostasis of the immune system. CTLA-4 is one among extensively studied co-stimulatory molecules which down-regulate immune response. The attributes of immunosuppressive qualities and capacity to induce tolerance have made its recognition as a potential immuno-therapeutic agent for autoimmune mediated inflammatory disorders. In 2007, European Medical Drug Agency (EMEA) has approved administration of CTLA-4Ig (commercial name: Orencia; generic name: Abatacept), as a mean for co-stimulation blockade, for treating patients with rheumatoid arthritis. This review is focused on working mechanism of CTLA-4 from its recognition (bench) to its usage as a potential therapeutic agent (bedside) for several inflammatory diseases. The efficacious aspects of chimeric CTLA-4 in phase I, II and III clinical trials for rheumatoid arthritis, psoriasis, multiple sclerosis are concisely described. This article highlights recent patents and the future usage of co-stimulatory molecules as a therapeutic agent providing a promising immuno-modulatory approach in regulating inflammation. | | Language | eng | | Pub Type(s) | Journal Article
