使用识别 γδ T 细胞受体 (TcR) 的常见或可变决定簇的单克隆抗体 (moAb) 来评估 30 名慢性皮肤红斑狼疮 (CCLE) 患者的活检标本和/或外周血白细胞 (PBL) 上的 γδ T 细胞分布。在来自 CCLE 病变患者的 15 个活检组织中评估了 CD3 + /γδ TcR + T 细胞,其数量占所有病变内 CD3 + T 细胞的 0.5% 至 15.0%。在来自病变皮肤的所有标本中,γδ TCR + T 细胞均为 BB3 + 和/或 TiyA +,表明主要使用 Vγ2/Vδ2 表型。在 CCLE 病变中,在靠近受损基底角质形成细胞 (KC) 层的位置观察到表皮内 Vγ2/Vδ2 + T 细胞,并且也随机散布在真皮中密集的炎症浸润中。与免疫组织学结果相反,30 名 CCLE 患者中的 28 名 PBL 中未观察到 γδ TcR + T 细胞数量增加。只有一名接受羟氯喹治疗两个月的 CCLE 患者 PBL 中 CD3 + /γδ TcR + T 细胞为 15%。根据免疫组织学结果,人们可以推断,在 CCLE(LE 的一种皮肤限制形式)中,Vγ2/Vδ2 + T 细胞在胸腺外扩张,以适应未知的刺激。人们还可能提出,这些 γδ T 细胞(基于其细胞毒性能力)可能会导致表皮损伤。 Vγ2/Vδ2+Tells 的胸腺外扩张是否发生在病变皮肤内,还是在随后募集到皮肤病变中的周围,仍有待确定。荧光激活细胞分选仪分析获得的结果支持第一种可能性
Monoclonal antibodies (moAbs) that recognize common or variable determinants of the γδ T-cell receptor (TcR) were used to assess γδ T-cell distribution on biopsy specimens and/or peripheral blood leukocytes (PBL) from 30 patients suffering from chronic cutaneous lupus erythematosus (CCLE). CD3 + /γδ TcR + T cells were evaluated in 15 biopsies from patients with CCLE lesions, their numbers varying from 0.5 to 15.0% of all intralesional CD3 + T cells present. In all specimens from lesional skin γδ TCR + T cells were BB3 + and/orTiyA +, indicating predominant use of the Vγ2/Vδ2 phenotype. In the CCLE lesions the intraepidermal Vγ2/Vδ2 + Tcells were observed in close vicinity to the damaged basal keratinocyte (KC) layer, and also randomly scattered among the densely packed inflammatory infiltrate in the dermis. In contrast to the immunohistologic findings, no numerical increase of γδ TcR + Tcells could be observed among PBL from 28 of 30 CCLE patients. Only one CCLE patient being treated with hydroxychloroquine for two months had 15% CD3 + /γδ TcR + Tcells among the PBL. Based on the immunohistologic findings one may infer that in CCLE, a skin-restricted form of LE, Vγ2/Vδ2 + T cells expand extrathymically to an as yet unknown stimulus. One may also propose that these γδ T cells - based on their cytotoxic capacity - may contribute to the epidermal damage. It remains to be determined whether the extra- thymic expansion of Vγ2/Vδ2+Tells occurs within lesional skin or in the periphery within subsequent recruitment into skin lesions. The results obtained by fluorescence-activated cell sorter analysis favor the first possibility
