答:Gr-1单抗通常认为是粒细胞标记,但实际上,它既可结合Ly-6G也可结合Ly-6C。大多数 Gr1+ CD11b- 细胞是 Ly6C+ LyG-,Ly6C可表达在浆细胞、部分粒细胞和T 细胞(包括记忆 T 细胞)表达。所以Gr1+ CD11b-细胞可能CD8是阳性的,如果补做CD8是阳性的...

《与Gr1+CD11b+髓系抑制细胞分化和功能有关的微小RNA研究》是依托南开大学，由杨荣存担任项目负责人的面上项目。中文摘要 Gr1+CD11b+髓系抑制细胞可由肿瘤与一些感染因素如病毒、细菌和寄生虫等诱导而大量产生,在产生免疫抑制、引导免疫逃逸过程中发挥着重要作用。研究免疫髓系抑制性细胞的关键在于搞清免疫髓...
CD11b(1) Gr1(1) bone marrow cells ameliorate liver fibrosis by pro- ducing interleukin-10 in mice. HEPATOLOGY 2012;56:1902-1912.Suh YG, Kim JK, Byun JS, Yi HS, Lee YS, Eun HS, et al. CD11b(+) Gr1(+) bone marrow cells ameliorate liver fibrosis by producing interleukin-10 in ...
Isolate highly purified mouse MDSCs (CD11b+Gr1+) from splenocytes, bone marrow, or peripheral blood in as little as 18 minutes with EasySep™.
Gr1(+)CD11b(+) cells expressed high levels of arginase-1, and IL-17, additional markers of myeloid derived suppressor cells. We then sorted the Gr1(hi) and Gr1(int) populations from M. tuberculosis infected NOS-/- mice and placed the sorted both Gr1(int) populations at different ratios ...
采用小鼠4T1乳腺癌模型观察MSC通过CD11b+Gr1+细胞对肿瘤生长的影响.结果 MSC能够促进骨髓中CD11b+Gr1+细胞的存活和生成,同时可诱导正常小鼠骨髓中CD11b+Gr1+细胞对T细胞的抑制作用.动物实验结果显示,MSC处理后的骨髓CD11b+Gr1+细胞可以促进肿瘤的生长,加速小鼠的死亡.结论 MSC可以通过促进骨髓来源的CD11b+Gr1+细胞...
CD11b+ Gr1dim Tolerogenic Dendritic Cell-like Cells are Expanded in Interstitial Lung Disease in SKG Mice.OBJECTIVE: SKG mice develop interstitial lung disease (ILD) resembling rheumatoid arthritis-associated ILD (RA-ILD) in human. The aim of this study is to clarify the mechanism behind the ...
目的探讨间充质干细胞(MSC)诱导骨髓来源的CD11b+Gr1+细胞免疫抑制功能对肿瘤的影响。方法将骨髓中CD11b+Gr1+细胞与MSC共培养后,通过流式细胞术测定CD11b+Gr1+细胞免疫表型,通过T细胞抑制性实验分析T细胞活化情况,采用小鼠4T1乳腺癌模型观察MSC通过CD11b+Gr1+细胞对肿瘤生长的影响。结果 MSC能够促进骨髓中CD11b+Gr1...
