doi: 10.1016/j.jare.2025.07.027

Figure Lengend Snippet: MMTs recruit a large number of MDSCs through CXCL10 pathway. A Significantly upregulated genes in MMTs versus non-MMT fibroblasts from OSCC database (GSA-Human: HRA007439). B Differences in CXCL10 expression between non-MMT fibroblasts and MMTs were demonstrated in HNSCC (figure S1). C CXCL10 expression and release were detected by PCR and ELISA. D-H Exogenous CXCL10 was added to BMDMs, while the CXCL10 inhibitor AMG487 was administered to MMTs, followed by co-culturing with MDSCs. The migration of MDSCs was evaluated using transwell chambers and crystal violet staining ( D ). Flow cytometry was used to detect cell apoptosis ( E ), macrophage markers (F4/80 + CD11b + ) ( F ), as well as CFSE for assessing T cell proliferation inhibition ( G ). PCR and ELISA were employed to measure the expression of immunosuppressive factors IL10 and iNOS ( H ). I, J Tumor tissue photographs ( I ) and the tumor growth curve were taken and subjected to statistical analysis regarding volume and weight ( J ). K-M Flow cytometry was used to detect the proportion of MDSCs in the spleen ( K ) and tumors ( L ) of each group, while immunofluorescence staining ( M ) revealed the densest field of MDSCs within the tumor tissues across all groups. Data are expressed as mean ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 vs experimental group. “ns” represents no statistical significance.

Figure Lengend Snippet: ( A-B ) Mice were dosed with 20 μg of STING conjugate delivered by LNP IP and serum was collected at 0, 1, 3, 6, 10, 24, and 50 h. Serum was analyzed to measure ( A ) STING conjugate concentration by Cy5 fluorescence (showing one phase exponential decay fit to data) and ( B ) CXCL10 concentration by ELISA (N = 3 mice). Conditions where analyte was below the limit of detection (LOD) are labeled as not detected (ND). ( C ) Mice were inoculated with 3×10 6 BPPNM cells IP and dosed with 20 μg of STING or Scr conjugate (N = 3 mice) delivered by LNP IP at 14 days after inoculation. ( D ) Omental tumor, ( E ) ascites, and ( F ) serum were collected 6 h after dosing. Concentrations of CXCL10, IFN-β, IL-6, TNF-α, and IFN-γ were measured by ELISA and are reported relative to total protein concentration in tumor and ascites ( D-E ) or relative to volume in serum ( F ). Conditions where analyte was below the LOD are labeled as ND. Average fold change increases in cytokine concentration for STING conjugate treatment compared to Scr conjugate are displayed. Where cytokine level was ND, a lower bound on the fold change was computed by setting all ND replicates as the LOD. Data represented as mean ± SD.
