Abstract

The effect of in vivo administration of monoclonal anti-L3T4 antibody on the development of murine collagen-induced arthritis (CIA) was assessed. Treatment with anti-L3T4 resulted in a greater than 90% depletion of L3T4+ T cells in lymph nodes and spleen, an effect that appears entirely reversed 30 d after treatment. Administration of anti-L3T4 before immunization with type II collagen resulted in a significant decrease in arthritis incidence and delayed onset of the disease while treatment begun after a strong anticollagen IgG humoral response was underway was not effective in altering disease expression. These results suggest a prominent role for L3T4+ T cells in the pathogenesis of CIA.

摘要

评估了体内给予单克隆抗L3T4抗体对小鼠胶原诱导性关节炎(CIA)发展的影响。用抗L3T4治疗导致淋巴结和脾脏中L3T4 + T细胞减少超过90%,这种效应在治疗后30天似乎完全逆转。在用II型胶原免疫前给予抗L3T4导致关节炎发病率显著降低且疾病发作延迟,而在强烈的抗胶原IgG体液反应开始后开始治疗对改变疾病表现无效。这些结果表明L3T4 + T细胞在CIA发病机制中起重要作用。
