T helper (Th) 1 and 17 cells play important roles in host protective responses against tuberculosis. Early Secretory Antigenic Target 6; a Region of Difference 1 (RD1) encoded protein, mounts Th17-responses in the lung. Therefore, lack of RD-1 region makes Bacillus Calmette-Guérin (BCG) less vaccine efficacious than parent strains.
辅助性T细胞（Th）1和17细胞在宿主抗结核保护性反应中发挥重要作用。早期分泌性抗原靶标6；差异区域1（RD1）编码蛋白在肺部引发Th17反应。因此，缺乏RD-1区域使得卡介苗（BCG）的疫苗效力低于亲本菌株。
