The immune system has been known to be capable of distinguishing self from non-self since the pioneering work of Paul Erhlich more than a century ago. Originally described in experiments studying blood transfusion comp- ibility, the principle of "horror autotoxicus" is still valid, although today the phenomenon is usually described in terms of tolerance or ignorance. A great deal has been learned about the various processes preventing self-reactivity normally. These include processes that operate during immune cell ontogeny and subsequently on reactivity of mature lymphocytes in the...

Leukocyte adhesion molecules have been the subject of intense basic and preclinical research. Results from clinical trials obtained sofar with antibodies directed towards these surface proteins offer promise for the prevention of graft rejection and effective treatment of acute and chronic inflammatory disease. This volume presents a comprehensive review of contemporary research on the structure, function and regulation of leukocyte adhesion molecules and their ligands, from the molecular to the clinical level. The blend of basic science and clinical applications presented in Structure,...
