Successful Anti-PD-1 Cancer Immunotherapy Requires T Cell …
2018年12月18日 · We tracked IFN-γ and IL-12p40 in vivo during rejection of aPD-1 treatment-sensitive MC38 tumor cells, which were labeled with H2B-mApple. We also tracked macrophages, which were tagged with Pacific-blue-dextran nanoparticles (Weissleder et al., 2014), as these cells are often abundant in tumors (Engblom et al., 2016).
Cell fusion potentiates tumor heterogeneity and reveals …
Stable cancer cell lines, MC38 (H2B-RFP), MC38 (H2B-RFP/Cre, B16F10 (H2B-RFP), and B16F10 (H2B-RFP/Cre), were generated by retroviral transduction using pBABE-based retroviruses, and polyclonal populations were selected by antibiotic resistance and flow-sorted for bright fluorescence as appropriate.
Arg1 expression defines immunosuppressive subsets of tumor …
MC38 cancer cells expressing H2B-mApple were implanted into the reporter mice, and tumors and other organs were harvested after 7 days. Animal tissues were subsequently analyzed with a panel of immune cell markers for Arg1 expression by flow cytometry (Figure 1 B).
TLR7/8-agonist-loaded nanoparticles promote the polarization …
2018年5月21日 · Here, we show that R848, an agonist of the toll-like receptors TLR7 and TLR8 identified in a morphometric-based screen, is a potent driver of the M1 phenotype in vitro and that R848-loaded β...
Frontiers | Host-functionalization of macrin nanoparticles to enable ...
2024年3月12日 · We implanted MC38-H2B-mApple tumor cells in IL12-eYFP reporter mice, which were treated with Pacific Blue-dextran as a macrophage-imaging agent to allow for the simultaneous visualization of tumor cells (mApple), TAMs (Pacific Blue) and TAM phenotype (co-expression of IL-12 and eYFP), respectively.
Expansion of tumor-associated Treg cells upon disruption of a …
2021年6月21日 · We transferred NFAT-GFP-expressing Treg cells into BMCs 3 weeks after bone marrow transfer, when the T cell compartment was not yet reconstituted, in order to enhance their engraftment. Another 3 weeks later, we implanted MC38 H2B-Cer tumors, installed DSFC, and treated animals either with DT or vehicle (Figure 2 A).

2024年12月2日 · 该细胞为已经稳定转染GFP的细胞,随细胞传代次数的增加,其GFP荧光强度会逐渐减弱。 若实验要求需要维持荧光强度,可以加入嘌呤霉素进行再次筛选。 1)收到细胞后,75%酒精消毒瓶壁将T25瓶置于室温放置约1h,若发现培养瓶破损、有液溢出及细胞有污染,请拍照后及时联系我们。 2)请在4或5X显微镜下确认细胞状态,同时给刚收到的细胞拍照(10×,20×)各2-3张以及培养瓶外观照片一张留存,作为售后时收到时细胞状态的依据。 3) …
光学显微技术和相干断层扫描技术在活体癌症研究中的应用|肿 …
2022年7月14日 · 磁共振成像(magnetic resonance imaging, MRI)和超声等临床成像技术能够对癌症的位置、解剖结构及其随时间的变化情况进行宏观测量,但无法测量病变的细胞和分子尺度细节。 活体显微(intravital microscopy, IVM)和光学相干断层扫描(optical coherency tomography, OCT)采用不同的成像机制,能达到亚细胞尺度的分辨率,促进临床和临床前的广泛研究(图1 )。 图1. IVM、OCT和标准临床成像模式间,空间分辨率与成像深度的对比示意图。
Macrophage calcium reporter mice reveal immune cell …
We implanted 1 million MC38-H2B-mCherry colon adenocarcinoma cells into the tissue underlying the window chamber to facilitate host immune cell recruitment. Within 24–72 h of MC38-H2B-mCherry cell implantation, we discovered host Csf1r Cre GCaMP5 fl reporter cells with highly dynamic calcium elevations.
