摘要
利用B7-1单抗和环孢素A(CsA)处理APCvT细胞反应系统,探讨了B7/CD28共刺激对T细胞增殖及细胞因子产生的影响,并用RT-PCR方法分析了细胞因子基因格局的改变。结果表明B7-1单抗可抑制特异性抗原诱导的T细胞增殖和IL-2的产生,B7-1单抗与CsA联用可阻断T细胞增殖和IL-2产生。B7-1单抗对IL-4的产生未显示明显的影响(P> 0.05),而B7-1单抗与CsA联用IL-4仍可检测到(P> 0.05)。B7-1单抗能抑制IL-2和γ-IFNm RNA表达,B7-1单抗与CsA联用能够阻断IL-2和γ-IFN m RNA表达,IL-4和IL-10m RNA仍能表达。
