摘要
CD22是B淋巴细胞表达的抗原,其在恶性淋巴瘤细胞上也高度表达。LL2是鼠源性抗CD22抗体,通过131I标记LL2用于复发的非霍奇金淋巴瘤的治疗,观察其疗效及毒副作用。Epratuzumab是人源化的LL2抗体,通过对套细胞淋巴瘤的Ⅰ/Ⅱ期临床试验研究,其有效率为18%,不产生人抗鼠抗体(HAMA)。Epratuzumab与Rituxan联合治疗提高疗效。临床研究表明抗CD22抗体作为新的免疫导向治疗药物具有很好的前景。
CD22 is an antigen expressed on the surface of B lymph cell,it is also have high expression on the cell of malignant lymphoma. LL2 (epratuzumab) is a routine IgO2a antibody to the CD22 antigen (transferring receptor), We observed its efficacy and toxicity of ^131I-lahalled-LL2 in the treatment of patients with recrudescent nonHodgkin lymphoma.Epratuzumab is a humanized LL2 (hLL2) monoclonal antibody, In phase Ⅰ/Ⅱ Trial of the treatment of mantle cell lymphoma, Epratuzumab didn't develope HAMA with the effective power of 18%, Using Epratuzumab and Rituxan in comblnation can promote their therapeutic efficacy. This review suggests that anti-CD22 antibody will have a good perspective as a new therapeutic medicine in immunal targeted therapy.
