为了表征人牙周病组织中TCR V基因的使用,检测了V α 2、V β 5.2-3、V β 5.3、V β 5.1、V β 6.7、V β 6.7、V β 8和V β 12.1的表达。从20例牙周炎和9例牙龈炎活检中获得的连续低温切片然后与针对每个库的单克隆抗体反应。该技术与灵敏的碱性磷酸酶-抗碱性磷酸酶法相结合。采集10例牙周炎和2例牙龈炎患者的外周血。还通过流式细胞荧光术用FITC缀合的抗体定量TCR库。对显示每种抗体结合的细胞进行计数。然后计算与CD 3阳性细胞的比例。每个TCR V基因产物的表达模式在发炎牙龈表现出个体差异,但出现了一致的模式。V β 5亚家族和V β 6.7是牙龈中常用的库,而V α 2和V β 8亚家族在大多数情况下表达不足。牙龈组织中TCR V基因产物的表达与自体外周血相比存在偏倚。10例牙周炎患者中有3例显示1或2种与自体血相比明显过度表达的剧目。在这3例受试者中,2例V β 6.7过表达,1例5.2-3、V β 8和V β 12.1过表达。这些结果表明,牙龈T细胞不是随机动员外周血和局部事件的影响TCR库的T细胞募集或T细胞扩增的水平。
In an attempt to characterize TCR V gene usage in human periodontally diseased tissue, V alpha 2, V beta 5.2-3, V beta 5.3, V beta 5.1, V beta 6.7, V beta 6.7, V beta 8 and V beta 12.1 expressions were examined. Serial cryostat sections obtained from 20 periodontitis and 9 gingivitis biopsies were then reacted with monoclonal antibodies directed to each repertoire. The technique was combined with a sensitive alkaline phosphatase-anti-alkaline phosphatase method. Peripheral blood was obtained from 10 periodontitis and 2 gingivitis patients. TCR repertoire was also quantified by flow cytofluorography with FITC-conjugated antibodies. Cells displaying binding of each antibody were counted. The proportions to CD3-positive cells were then calculated. The pattern of each TCR V gene product expression in inflamed gingiva exhibited individual variation, nevertheless, a consistent pattern emerged. The V beta 5 subfamily and V beta 6.7 were frequently used repertoires in gingiva, whereas the V alpha 2 and V beta 8 subfamily were underexpressed in most cases. Furthermore, the TCR V gene product expression in gingival tissue was biased compared with autologous peripheral blood. Three of 10 periodontitis subjects showed 1 or 2 strikingly overrepresented repertoire comparatively with autologous blood. In these 3 subjects V beta 6.7 was overexpressed in two cases and 5.2-3, V beta 8 and V beta 12.1 were overexpressed in one case. These results suggest that gingival T-cells are not randomly mobilized from peripheral blood and that local events influence the TCR repertoire at the level of T-cell recruitment or T-cell expansion.
