Abstract:Autoantibiodies against aminoacyl-tRNA synthetases are found in patients suffering from a
wide range of autoimmune and inflammatory disorders. Recent data indicate that these antibodies are
directed against splice-variants of synthetase genes, the so-called catalytic nulls. Latter molecules have
cytokine-like functions and are involved in the regulation of the activation of lymphocytes, monocytes
and granulocytes. The potential role of anti-synthetase antibodies as a diagnostic tool and a target for
therapeutic interventions is discussed.
