摘要：
Disclosed are methods and compositions of anti-B cell antibodies, preferably anti-CD22 antibodies, for diagnosis, prognosis and therapy of B-cell associated diseases, such as B-cell malignancies, autoimmune disease and immune dysfunction disease. Preferably, the antibodies induce trogocytosis of B-cell antigens, such as CD19, CD20, CD21, CD22, CD79b, CD44, CD62L, or β7-integrin. Trogocytosis may play a significant role in determining antibody efficacy, disease responsiveness and prognosis of therapeutic intervention and trogocytosis-dependent responses may be monitored by measuring the levels of trogocytosis of one or more B-cell surface antigens induced by the bispecific antibody.
