Alefacept(抗CD 2)生物治疗选择性靶向效应记忆T细胞(Tem)在寻常型银屑病,1型自身免疫性疾病模型。在接受阿法西普治疗中重度银屑病的患者中,对循环白细胞进行表型分析。在所有患者中,这种治疗导致效应记忆T细胞(CCR 7-CD 45 RA-)的CD 4+和CD 8 + Tem的优先减少(平均减少63%),而中央记忆T细胞(Tcm)(CCR 7 + CD 45 RA-)受影响较小,幼稚T细胞(CCR 7 + CD 45 RA+)相对较少。循环CD 8+效应T细胞和1型T细胞(产生IFN-γ)也显着减少。Alefacept可导致银屑病患者循环效应记忆T细胞(Tem)选择性减少和中枢记忆T细胞(Tcm)相对保留。
Alefacept (anti-CD2) biological therapy selectively targets effector memory T cells (Tem) in psoriasis vulgaris, a model Type 1 autoimmune disease. Circulating leukocytes were phenotyped in patients receiving alefacept for moderate to severe psoriasis. In all patients, this treatment caused a preferential decrease in effector memory T cells (CCR7- CD45RA-) (mean 63% reduction) for both CD4+ and CD8+ Tem, while central memory T cells (Tcm) (CCR7+CD45RA-) were less affected, and naïve T cells (CCR7+CD45RA+) were relatively spared. Circulating CD8+ effector T cells and Type 1 T cells (IFN-γ-producing) were also significantly reduced. Alefacept causes a selective reduction in circulating effector memory T cells (Tem) and relative preservation of central memory T cells (Tcm) in psoriasis.
