V gamma 9V delta 2 T lymphocytes strongly respond to phosphoantigens from Plasmodium parasites. Thus, we analyzed the changes in V gamma 9V delta 2 T-cell function and repertoire during the paroxysm phase of nonendemic malaria infection. During malaria paroxysm, V gamma 9V delta 2 T cells were early activated but rapidly became anergic and finally loose J gamma 1.2 V gamma 9 complementarity-determining region 3 transcripts.
Vγ9Vδ2 T淋巴细胞对疟原虫的磷酸抗原有强烈反应。因此,我们分析了非流行地区疟疾感染发作期Vγ9Vδ2 T细胞功能和谱系的变化。在疟疾发作期间,Vγ9Vδ2 T细胞早期被激活,但很快变得无反应,并最终丢失Jγ1.2 Vγ9互补决定区3转录本。
