PG - 61-73 AB - Treatment of Lewis rats with monoclonal anti-interleukin-2 receptor (IL-2 R) antibody ART-18 is highly efficient in protecting the recipients from T-line transferred experimental autoimmune encephalomyelitis (tEAE) in vivo. In contrast, ART-18 did not affect the development of EAE actively induced (aEAE) by immunization with myelin basic protein (MBP) in complete Freund's adjuvant (CFA). ART-18 caused a slight delay in the development of aEAE only in combination with a subtherapeutic dose of cyclosporine A (Cy-A), but failed to influence duration or severity of clinical signs. The discrepancy in therapeutic efficiency of ART-18 in tEAE and aEAE could be due to a different intensity of IL-2 R-expression on in vitro- and in vivo-activated MBP-specific T cells. Our results therefore caution against a general therapeutic application of anti IL-2 R-directed therapy in all manifestations of T-cell-mediated autoimmunity.
