Oncolytic measles and mumps viruses (MeV, MuV) have a potential for anti-cancer treatment. We examined the anti-tumor activity of MeV, MuV, and MeV-MuV combination (MM) against human solid malignancies (HSM). MeV, MuV, and MM targeted and significantly killed various cancer cell lines of HSM but not normal cells. MM demonstrated a greater anti-tumor effect and prolonged survival in a human prostate cancer xenograft tumor model compared to MeV and MuV. MeV, MuV, and MM significantly induced the expression of immunogenic cell death markers and enhanced spleen-infiltrating immune cells. In conclusion, MM combination significantly improves the treatment of human solid malignancies.

BackgroundAdipokines are involved in the pathogenesis of metabolic disorders including obesity and type 2 diabetes mellitus (T2DM). This study investigates the levels of leptin, resistin, visfatin, secreted frizzled-related protein 5 (SFRP5), monocyte chemoattractant protein-1 (MCP-1) and retinol-binding protein 4 (RBP4) and their correlations with clinical parameters of overweight and T2DM.MethodsWe recruited overweight 50 patients with T2DM, 88 non-overweight patients with T2DM, 29 overweight and 100 non-overweight individuals devoid of T2DM for this study. The levels of studied adipokines were measured by enzyme-linked immunosorbent assay and correlated with clinical parameters.ResultsThe levels of MCP-1 and SFRP5 were decreased while visfatin and RBP4 levels were increased in patients with T2DM compared to those in the control individuals (P < 0.01). Among patients with T2DM, leptin and resistin levels were higher while RBP4 levels were lower in patients with overweight T2DM compared to those in patients with non-overweight T2DM (P < 0.0001, 0.019 and 0.05, respectively). Leptin and MCP-1 levels were correlated with HOMA-IR, QUICKI and HOMA-β. Leptin/MCP-1 ratio was correlated with insulin levels, HOMA-IR and HOMA-β indexes. Resistin/RBP4, visfatin/MCP-1 and MCP-1/RBP4 ratios were strongly correlated with the levels of fasting glucose, HbA1c and HOMA-β. In addition, ROC curve analyses indicated a diagnostic potential of resistin/RBP4 and MCP-1/RBP4 indexes for T2DM (AUC = 0.81 and 0.83, respectively) and β-cell function (AUC = 0.76 and 0.74, respectively).ConclusionsAdipokines (leptin, resistin, visfatin, SFRP5, MCP-1, and RBP4) are associated with overweight and T2DM and may serve as a potential prognostic marker and therapeutic intervention for overweight-related T2DM.

The clinical outcome of dengue is due to a complex interplay between dengue virus (DENV) and host immune factors, including complement and cytokine systems. Proinflammatory cytokines are mainly produced by monocytes in response to infectious pathogens. This study investigated the levels of proinflammatory cytokines, including tumor necrosis factor-a (TNF-a), interleukin-1 beta (IL-1b), and IL-12 in Vietnamese patients with dengue, and their correlations with the clinical outcome of dengue infection in 156 patients clinically classified as dengue without warning signs (DWS-, n = 87), dengue with warning signs (DWS+, n = 62), and severe dengue (SD, n = 7) patients as well as in 60 healthy controls (HCs). Serum TNF-a, IL-1b, and IL-12 levels were quantified by enzyme-linked immunosorbent assay (ELISA). The results showed that TNF-a, IL-1b, and IL-12 levels were significantly increased in dengue patients compared with HCs (p < 0.0001). TNF-a levels were significantly correlated with white blood cells and platelet counts (r s = 0.52, 0.2; p < 0.0001, p = 0.018, respectively). IL-1b levels were correlated with red blood cells counts and the levels of aspartate aminotransferase and alanine aminotransferase (r s = 0.23, 0.21, 0.23; p = 0.004, 0.012, 0.005, respectively). The results suggest that these three proinflammatory cytokines are associated with the clinical outcome of dengue and could play roles in the pathogenesis of the disease.
