    Ectopic Sestrin2 expression in M1 macrophages attenuates post-MI inflammation and favors tissue repair in hearts. (A) Macrophage abundance in infarcted myocardium at day 3 after myocardial infarction (MI) (day 4 after Clophosome ® treatment). Ctrl: un-pretreated mice. Depletion: Clophosome ® injection. Depletion + M (L-C): Clophosome ® injection followed by transfer of M1 macrophages transduced with control lentivirus. Depletion + M (L-S): Clophosome ® injection followed by transfer of M1 macrophages transduced with SESN2 lentiviral activation particles. Numbers in the plots are proportions of gated cells populations. This is a representative of two independent experiments. (B,C) mRNA abundance of indicated cytokines and chemokines in infarcted myocardium. (D,E) Percentage of Gr-1 + neutrophils in the whole cardiac cells at day 3 after MI. Representative flow <t>cytometry</t> dot plots are shown in (D) , and statistics is shown in (E) . (F) Masson staining at day 7 after MI. Left panel: representative images. Right panel: statistics of collagen volume fraction (CVF). N = 4–5 per group. * p

    miR-26a reduces CTL cytotoxicity against tumor cells in vitro . (A) Relative gene expression values for miR-26a in CTLs from Mir26a -Tg mice. CTLs from WT mice were used as a control (n = 5). (B) MACS-purified naïve CD8 + T cells were activated using anti-CD3 and anti-CD28 antibodies for 2 d, and flow <t>cytometry</t> was used to assess CTL effector molecule expression. Both the expression percentage and MFI are shown (n = 5). (C, D) qPCR analysis of granzyme B and IFNγ expression was also performed in CTLs from Mir26a -Tg mice and WT mice (n = 5). (E) CTLs from WT or Mir26a -Tg mice were incubated with target cells (EL4 cells) for 6 h. The ratios of target cells: effector cells were 1:1, 1:5, 1:10, and 1:20. Error bars in the curve represent the SD among four mice. Statistically-significant differences were measured using an unpaired Student's t -test (A, C, D, and E) and a paired Student's t -test (B), * p

Culture supernatants from ZIKV-infected PBMCs were harvested and used to infect Vero cells for two days followed by intracellular staining with an anti-E antibody and flow cytometry analysis. Representative results of the boosted infection assay on Vero cells for the DENV immune serum D1-01 (B) and the control serum Naïve-01 (D) were shown.

    Resistin increases the expression of ABC transporters in myeloma cells. ARP-1 and MM.1S myeloma cells were cultured with resistin (50 ng/mL) for 12 h. Some of the cultured cells were labeled with eFluxx-ID gold fluorescent dye and further analyzed by flow cytometry. Others were subjected to RNA or protein extraction for real-time PCR or western blot analysis. (A) Intracellular eFluxx-ID gold fluorescence intensity was quantified. PBS, phosphate-buffered saline solution (controls). (B) Real-time PCR shows relative mRNA expression of ABC transporter genes. (C) Western blot analysis shows expression of ABCG2 and ABCC5 proteins. Cells cultured without resistin served as controls. GAPDH served as a protein loading control. (D) Real-time PCR analysis shows relative expression levels of ABCC5 and ABCG2 mRNA in ARP-1 or MM.1S cells bearing non-targeted siRNA ( si Ctrl) or the pooled siRNA of ABCC5 ( si C5) and ABCG2 ( si G2).

    Resistin protects myeloma from chemotherapy in vivo . SCID mice were injected with ARP-1 myeloma cells (5×10 5 cells per mouse) directly into the femur (n=5 mice per group). Three weeks after ARP-1 cell injection, mice began intraperitoneal treatment with melphalan (Mel; 50 μg/mouse), resistin (20 μg/mouse), or both every 3 days for 3 weeks. After treatment, the mouse sera were subjected to enzyme-linked immusorbent assay to measure M-protein levels. After the mice had been euthanized, the cells flushed from each mouse’s femoral bone marrow cavity were labeled with an antibody against human CD138, and the CD138 + cells were sorted by flow cytometry. CD138 + cells were subjected to an annexin V binding assay to determine cell apoptosis. The mouse femora were analyzed with an in situ TUNEL assay. Mice that received neither melphalan nor resistin served as controls. (A) Relative levels of M-proteins. (B) Percentages of CD138 + cells. (C) Percentages of apoptotic CD138 + cells. (D) Representative images of TUNEL + cells in bone marrow. (E) Quantitative analysis of TUNEL staining. Bar: 20 μm. Original magnification × 200. The results shown represent averages ± SD (n = 5 mice/group, 3 replicate studies). * P
