Foxp3-expressing regulatory T (Treg) cells represent the most highly immunosuppressive cell in tumor microenvironment (TME) that halts effective anti-tumor immunity. Osteopontin (Opn), an extracellular matrix (ECM) glycophosphoprotein, plays key roles many types of immune-related diseases and is associated with cancer aggressiveness when expressed by cells.

Solid tumors develop within a complex environment called the tumor microenvironment (TME), which is sculpted by presence of other cells, such as cancer-associated fibroblasts (CAFs) and immune cells like macrophages (Mφs). Despite orchestrate tumor-supportive through intricate interaction with components TME. However, specific mechanism this intercellular dialogue regulated not fully understood. To that end, development an organotypic 3D breast TME-on-a-chip (TMEC) model, integrated single-cell RNA sequencing analysis, reported to mechanistically evaluate progression triple-negative cancer (TNBC) in patient-derived CAFs Mφs. Extensive functional assays, including invasion morphometric characterization, reveal synergistic influence Mφs on cells. Furthermore, gene expression pathway enrichment analyses identify involvement KYNU gene, suggesting potential evasion kynurenine pathway. Lastly, pharmacological targeting identified investigated.

Abstract It has been found that progression from leukoplakia to head and neck squamous cell carcinoma (HNSCC) is a long-term process may involve changes in the multicellular ecosystem. We acquired scRNA-seq samples information gene expression omnibus UCSC Xena database. The BEAM function was used construct pseudotime trajectory analyze differentially expressed genes different branches. ssGSEA method explore correlation between each subgroup survival time, obtained related prognosis. During HNSCC, we several prognostic subgroups, such as AURKB + epithelial cells, SFRP1 fibroblasts, SLC7A8 macrophages, FCER1A CD1C dendritic TRGC2 NK/T cells. All subgroups had two fates, one tending proliferation, migration, enhancement of angiogenesis capacity, other inflammatory immune response, leukocyte chemotaxis, T activation. Tumor-promoting CD163 CD209 were highly myeloid depletion marker TIGIT, LAG3 Our study provide reference for molecular mechanism HNSCC theoretical basis development new therapeutic strategies.
