Extracellular ATP at millimolar concentrations inhibits growth of mycobacteria in human macrophages. Whether T cells can produce sufficient ATP is unknown. CD4(+) and CD8(+) T cells did not release sufficient ATP through either degranulation or lysis of bystander cells to restrict growth of Mycobacterium bovis BCG in monocytes.
毫摩尔浓度的细胞外ATP可抑制人巨噬细胞中分枝杆菌的生长。T细胞是否能产生足够的ATP尚不清楚。CD4(+)和CD8(+) T细胞通过脱颗粒或旁观者细胞裂解均未释放足够的ATP来限制单核细胞中牛分枝杆菌卡介苗的生长。
