在非脓疱性银屑病中,主要可以区分两种形式 [Christophers E. Henseler T:银屑病的患者亚组和炎症模式。 Acta Dermatol Venereol 69(suppl 151):88-92, 1989):I 型经常显示阳性家族史、人类白细胞抗原 (HLA) Cw6、B13 和 Bw57 连锁不平衡以及早期发病。 II 型在 5 岁左右出现,与 Cw2 和 B27 相关的频率比正常情况更高。鉴于与 HLA 的这种关联,已经讨论了自身免疫发病机制。为了研究 T 细胞的致病功能,我们对 I 型 (n = 10) 和 II 型 (n = 10) 银屑病患者进行了活检。使用针对 T 细胞受体 (TCR) 的 β 链的 5 个可变 (V) 区(V β 5a、V β 5b、V β 6、V β 8、V β 12)和 T 细胞受体 (TCR) 的 α 链 (V α 2) 之一的一组单克隆抗体进行三步过氧化物酶染色。在可证明的库中无法检测到特定 TCR V 区域的正向或负向选择。此外,所调查的 V 区的使用揭示了两种形式的牛皮癣的相似模式。
In nonpustular psoriasis, principally two forms can be distinguished [Christophers E. Henseler T: Patient subgroups and the inflammatory pattern in psoriasis. Acta Dermatol Venereol 69(suppl 151):88-92, 1989): Type I frequently shows positive family history, linkage disequilibrium for human leucocyte antigens (HLAs) Cw6, B13 and Bw57 as well as an early onset. Type II manifests itself around the 5th decade, it is more frequently than normal associated with Cw2 and B27. In the light of this association with HLAs an autoimmune pathogenesis has been discussed. In order to investigate the pathogenetic function of T cells we obtained biopsies from patients with type I (n = 10) and type II (n = 10) psoriasis. Three-step peroxidase staining was performed using a panel of monoclonal antibodies directed against five variable (V) regions of the beta chain (V beta 5a, V beta 5b, V beta 6, V beta 8, V beta 12) and one of the alpha chain (V alpha 2) of the T cell receptor (TCR). Positive or negative selection of a particular TCR V region could not be detected in the demonstrable repertoire. Furthermore, the usage of the V regions under investigation revealed a similar pattern in the two forms of psoriasis.
