摘要

目的:探讨肠巨噬细胞髓系细胞触发受体-l(triggering receptor expressed on myeloid cells-1,TREM-1)的表达对肠巨噬细胞侵袭力和肠上皮细胞增殖的影响,进一步明确肠巨噬细胞在肠屏障功能障碍(intestinal barrier dysfunction,IBD)中可能的作用.方法:体外培养肠巨噬细胞及肠上皮细胞,逆转录-多聚酶链反应(reverse transcription-polymerase chain reaction,RT-PCR)检测大鼠肠巨噬细胞的TREM-1和肿瘤坏死因子-α(tumor necrosis factor-α,TNF...
