Article Title: High-fat diet-induced upregulation of exosomal phosphatidylcholine contributes to insulin resistance

doi: 10.1038/s41467-020-20500-w

Figure Lengend Snippet: a Plasma and WAT cytokine array of mice that received CD63 + A33 + exosomes (L-Exo or H-Exo) for 14 days. b Fold change in H-Exo vs. L-Exo-induced plasma cytokine expression for all cytokines showing greater than two-fold change. Red bars show cytokines/factors known to be involved in insulin resistance. c TNF-α (left) and IL-6 (right) upregulation following treatment with H-Exo were confirmed by ELISA in plasma. Filled circle—PBS, filled triangle—L-Exo, and filled rectangle—H-Exo. d ITT performed on C57BL/6 mice that received exosomes via adoptive transfer for 14 days followed with or without macrophage depletion. Filled rectangle—macrophage-depleted mice treated with H-Exo; filled diamond—mice without macrophage depletion treated with PBS and circle—mice without macrophage depletion treated with H-Exo. e Glucose uptake assay performed on hepatocytes cultured with different concentrations of H-Exo (as indicated in the figure). f Glucose uptake assay performed on mouse hepatocytes supplemented with supernatant derived from macrophages cultured with nanoparticles derived from H-Exo total lipids (H-Exo Nano) and PC (34:2). g Supernatants from H-Exo-treated macrophages (monocytes+ 5 × 10 6 ) were preneutralized with anti-TNF-α and/or anti-IL-6 antibodies. Glucose uptake by hepatocytes cultured in the presence of preneutralized supernatant was estimated. Data are represented as the mean ± SD. One-way ANOVA with a Tukey post hoc test. * < 0.05; **** < 0.0001. Source data are provided as a Source Data file.

Article Title: Temporal Regulation of Early-Stage Cytokine Expression in Diabetic Wound Healing Under Negative Pressure Wound Therapy

doi: 10.3390/ijms26104634

Figure Lengend Snippet: Cytokine expression in diabetic wound healing. Cytokine expression profiles in type 2 diabetic mouse model at four-time points: 0, 0.5, 2, and 16 h after wounding under two pressure conditions: AP and NP. Color frames indicate wound healing stages (early to late): hemostasis (orange), inflammation (red), inflammation and proliferation (purple), proliferation (blue), and remodeling (grey). Rows A through J represent cytokine target spots based on the predefined array layout of the Mouse XL Cytokine Array (R&D Systems). For details on spot assignments and cytokine identities, please refer to the product documentation provided by the manufacturer.

Article Title: Temporal Regulation of Early-Stage Cytokine Expression in Diabetic Wound Healing Under Negative Pressure Wound Therapy

doi: 10.3390/ijms26104634

Figure Lengend Snippet: Overview of the experimental design and cytokine analysis. Diabetic (DB) mice were treated with atmospheric pressure (AP) or negative pressure wound therapy (NP), with serum collected at 0, 0.5, 2, and 16 h post-wounding for cytokine array analysis. Previously published wild-type (WT) data were used as a reference. Heatmaps and time-course plots visualize cytokine expression dynamics. A one-sided binomial test was applied to assess statistically significant shifts in cytokine peak timing between groups.

doi: 10.1101/2025.09.01.673552

Figure Lengend Snippet: Representative flow cytometry contour plots of PD-1 x CXCR5 expression within CD25-CD4+ T cells isolated from NCD (left) and HFD (right) mouse spleen (top) and liver (bottom) ( A ). Blue gates represent PD-1 HI CXCR5+ cells, yellow gates represent PD-1 HI CXCR5-cells, and black gates represent PD-1-cells ( A ). Frequency and absolute number of PD-1 HI CXCR5+ T FH cells ( B , blue), or PD-1 HI CXCR5-T PH cells ( C , yellow) within the CD25-CD4+ T cell compartments of spleen (top) and liver (bottom) of NCD (grey) and HFD (blue/yellow) mice. Quantification of Bcl-6 ( D ), ICOS ( E ), and T-bet ( F ) protein expression (gMFI) in splenic (left) or hepatic (right) CD25-CD4+ T cell subsets. Representative flow cytometry contour plots depicting relative expression of IL-21 and IFNg by PD-1 HI CXCR5+ T FH cells or PD-1 HI CXCR5-T PH cells from spleen (top) or liver (bottom) that are also CXCR3+ (blue/red) or CXCR3-(black) ( G ). Summary of frequency of IL-21 ( H,J; left) or IFNg ( I,K ; right) producing CD4+ PD-1 HI CXCR5+ T FH (blue) or PD-1 HI CXCR5-T PH (red) cells categorized by CXCR3+ expression as noted in spleen ( H, I ) or liver ( J,K ) from HFD-fed mice.
