使用FLAG标签肽及慢病毒载体共同筛选小鼠foxp3基因RNA干扰的有效靶点

Zhongshan Daxue xuebao. Yixue kexue ban, 2007
【目的】筛选高效的foxp3 RNA干扰的靶点用于阻断CD4^＋CD25^＋ Treg细胞的免疫抑制功能。【方法】使用oligoengine软件设计foxp3基因shRNA序列，化学合成法合成4条shRNA序列，构建含foxp3的靶序列的慢病毒载体：构建出表达FLAG融合蛋白和目的基因的工具细胞293T细胞用于筛选RNA干扰的有效靶点。【结果】成功包装了4条foxp3基因靶序列相应的慢病毒颗粒；成功构建了表达融合蛋白和目的基因的293T工具细胞：在工具细胞上筛选出了2条RNAi效率分别为91.3％和95．

Regulatory T cells and Foxp3 [PDF]

Immunological Reviews, 2011
Summary:  Regulatory T (Treg) cells play central role in regulation of immune responses to self‐antigens, allergens, and commensal microbiota as well as immune responses to infectious agents and tumors. Transcriptional factor Foxp3 serves as a lineage specification factor of Treg cells.

FAPα+ Macrophages Orchestrate Immune Evasion in Multiple Myeloma by Dual Regulation of PD‐L1 and T Cell Senescence

Advanced Science, EarlyView.
Fibroblast activation protein alpha‐positive (FAPα+) macrophages, a distinct subset of multiple myeloma (MM)‐associated macrophages, drive immune evasion in MM through multi‐faceted mechanisms. FAPα physically interacts with vimentin (VIM) and triggers its phosphorylation at the S72 residue, which in turn induces PD‐L1 transcription. Additionally, FAPα

Kickstarting Foxp3 with c-Rel [PDF]

Immunity, 2009
In this issue of Immunity, reports by Long et al. (2009) and Ruan et al. (2009) suggest that the transcription factor NF-kappaB-c-Rel is an important molecular mechanism by which T cell receptor-specificity for self-antigens instructs the selection of Foxp3(+) regulatory T cells.

Interactions of Antibody Drug Conjugate Anti‐Tubulin and Topoisomerase I Inhibitor Payloads with Radiotherapy to Potentiate Immunotherapy

Advanced Science, EarlyView.
Antibody drug conjugates deliver their cytotoxic anti‐tubulin or topoisomerase I inhibitor payloads to tumors through cancer cell receptor targeting. The released drug payloads induce cellular changes that interact with radiotherapy resulting in radiosensitization that improves cancer cell kill and stimulates anti‐tumor immune responses.

Circulating Tumour Cells and FOXP3 in Regulatory T-Cells as New Modalities in Cancer Diagnosis and Metastasis Location Prediction

Acta Medica Indonesiana, 2023
Cancer is a complex group of diseases which arises from uncontrolled growth and spread of abnormal cells in the body. The pathophysiology of cancer involves a sequence of events at the cellular and molecular levels, often initiated by genetic mutations ...

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,
