Alpha-mangostin inhibits viral replication and suppresses nuclear factor kappa B (NF-κB)-mediated inflammation in dengue virus infection. Sci Rep 2022; 12:16088.

Abstract
Severe dengue virus (DENV) infection results from viral replication and dysregulated host immune response, which trigger massive cytokine production/cytokine storm. The result is severe vascular leakage, hemorrhagic diathesis, and organ dysfunction. Subsequent to previously proposing that an ideal drug for treatment of DENV infection should efficiently inhibit both virus production and cytokine storm, we discovered that α-mangostin (α-MG) from the pericarp of the mangosteen fruit could inhibit both DENV infection and cytokine/chemokine production. In this study, we investigated the molecular mechanisms underlying the antiviral and anti-inflammatory effects of α-MG. Time-of-drug-addition and time-of-drug-elimination studies suggested that α-MG inhibits the replication step of the DENV life cycle. α-MG inhibited polymerization activity of RNA-dependent RNA polymerase (RdRp) with IC50 values of 16.50 μM and significantly reduced viral RNA and protein syntheses, and virion production. Antiviral and cytokine/chemokine gene expression profiles of α-MG-treated DENV-2-infected cells were investigated by polymerase chain reaction array. α-MG suppressed the expression of 37 antiviral and cytokine/chemokine genes that relate to the NF-κB signaling pathway. Immunofluorescence and immunoblot analyses revealed that α-MG inhibits NF-κB nuclear translocation in DENV-2-infected cells in association with reduced RANTES, IP-10, TNF-α, and IL-6 production. These results suggest α-MG as a potential treatment for DENV infection.

Abstract
Since severe dengue virus (DENV) infection in humans associates with both high viral load and massive cytokine production - referred to as "cytokine storm", an ideal drug for treatment of DENV infection should efficiently inhibit both virus production and cytokine expression. In searching for such an ideal drug, we discovered that α-mangostin (α-MG), a major bioactive compound purified from the pericarp of the mangosteen fruit (Garcinia mangostana Linn), which has been used in traditional medicine for several conditions including trauma, diarrhea, wound infection, pain, fever, and convulsion, inhibits both DENV production in cultured hepatocellular carcinoma HepG2 and Huh-7 cells, and cytokine/chemokine expression in HepG2 cells. α-MG could also efficiently inhibit all four serotypes of DENV. Treatment of DENV-infected cells with α-MG (20μM) significantly reduced the infection rates of four DENV serotypes by 47-55%. α-MG completely inhibited production of DENV-1 and DENV-3, and markedly reduced production of DENV-2 and DENV-4 by 100 folds. Furthermore, it could markedly reduce cytokine (IL-6 and TNF-α) and chemokine (RANTES, MIP-1β, and IP-10) transcription. These actions of α-MG are more potent than those of antiviral agent (ribavirin) and anti-inflammatory drug (dexamethasone). Thus, α-MG is potential to be further developed as therapeutic agent for DENV infection.

Abstract
The serum levels of beta interferon (IFN-β) were evaluated in clinical samples taken in the acute phase of dengue fever for 107 patients during the 2011 dengue outbreak in Yucatán, México. Dengue diagnoses were confirmed by NS1 or IgM/IgG serology in all patients. Average serum IFN-β levels in patients with dengue fever without warning signs (n = 53) were 140 pg/ml, and 105 pg/ml for patients with warning signs (n = 54). There was no statistically significant difference between IFN-β levels for the two groups (Mann-Whitney U Test P > 0.05) and no association with warning or mild signs (OR: 0.57; 95%CI: 0.26-1.22) was indicated. Thrombocytopenia was the most prevalent warning sign (91%) in one group of patients (49) with mean 113 pg/ml IFN-β levels. In contrast, the patients without thrombocytopenia (50) had 126 pg/ml of IFN-β, but this level was not statistically significant (Mann-Whitney U Test P > 0.05). The average levels of IFN-β were also found to have statistically similar results, using the 1997 WHO classification system. The amount of IFN-β at 1-3, 4-6, and 7-9 days after onset of illness, however, did show significant differences (ANOVA P = 0.038) between patients for the 1-3 and 4-6 days pair (Scheffe post-hoc P = 0.043). These results suggest that serum levels of IFN-β do not correlate well with the severity of dengue illness, but there is a clear association between changes in IFN-β levels and the days of evolution during the acute phase of the disease.

Abstract
The arthropod-borne diseases caused by dengue virus (DENV) are a major and emerging problem of public health worldwide. Infection with DENV causes a series of clinical manifestations ranging from mild flu syndrome to severe diseases that include hemorrhage and shock. It has been demonstrated that the innate immune response plays a key role in DENV pathogenesis. However, in recent years, it was shown that DENV evades the innate immune response by blocking type I interferon (IFN-I). It has been demonstrated that DENV can inhibit both the production and the signaling of IFN-I. The viral proteins, NS2A and NS3, inhibit IFN-I production by degrading cellular signaling molecules. In addition, the viral proteins, NS2A, NS4A, NS4B, and NS5, can inhibit IFN-I signaling by blocking the phosphorylation of the STAT1 and STAT2 molecules. Finally, NS5 mediates the degradation of STAT2 using the proteasome machinery. In this study, we briefly review the most recent insights regarding the IFN-I response to DENV infection and its implication for pathogenesis.

Abstract
Background Dengue Virus (DENV) is the most common mosquito-borne viral infection worldwide. Important target cells during DENV infection are macrophages, monocytes, and immature dendritic cells (imDCs). DENV-infected cells are known to secrete a large number of partially immature and fully immature particles alongside mature virions. Fully immature DENV particles are considered non-infectious, but antibodies have been shown to rescue their infectious properties. This suggests that immature DENV particles only contribute to the viral load observed in patients with a heterologous DENV re-infection. Methodology/Principal findings In this study, we re-evaluated the infectious properties of fully immature particles in absence and presence of anti-DENV human serum. We show that immature DENV is infectious in cells expressing DC-SIGN. Furthermore, we demonstrate that immature dendritic cells, in contrast to macrophage-like cells, do not support antibody-dependent enhancement of immature DENV. Conclusions/Significance Our data shows that immature DENV can infect imDCs through interaction with DC-SIGN, suggesting that immature and partially immature DENV particles may contribute to dengue pathogenesis during primary infection. Furthermore, since antibodies do not further stimulate DENV infectivity on imDCs we propose that macrophages/monocytes rather than imDCs contribute to the increased viral load observed during severe heterotypic DENV re-infections.

Abstract
BACKGROUND The production of type I interferon alpha/beta (IFN-α/β) is crucial to viral clearance during dengue virus (DENV) infection; however, in vitro-infected dendritic cells (DCs) exhibit a decreased capacity to respond to IFN-α/β stimulation, and antigen-presenting cells (APCs) isolated from patients with acute DENV infection exhibit defects in T cell priming. METHODS In order to ascertain the stimulatory capacity of primary human monocyte-derived DCs infected with wild-type DENV isolates, representing a range of genotypes and disease outcomes, we cocultured infected DCs with allogeneic-naive CD4(+) T cells. The gene expression patterns of IFN-α/β sensitive genes were quantitated to determine if the infected DCs displayed a blunted IFN-α/β response. RESULTS DENV-infected DCs induced the initial proliferation of naive CD4(+) T cells but they remained nonpolarized in effector function. The expression of IFN-α/β-stimulated genes was downregulated, revealing that the inhibition of IFN-α/β signaling is conserved among endemic DENV serotype 2 strains. CONCLUSIONS The failure of naive CD4(+) T cells to differentiate into IFN gamma-producing effector T cells when primed by DENV-infected DCs cannot be explained solely by a block in IFN-α/β signaling, suggesting that the ability of DENV to evade the early host response is multifaceted.

Abstract
Dengue virus (DENV 1-4) represents a major emerging arthropod-borne pathogen. All four DENV serotypes are prevalent in the (sub) tropical regions of the world and infect 50-100 million individuals annually. Whereas the majority of DENV infections proceed asymptomatically or result in self-limited dengue fever, an increasing number of patients present more severe manifestations, such as dengue hemorrhagic fever and dengue shock syndrome. In this review we will give an overview of the infectious life cycle of DENV and will discuss the viral and host factors that are important in controlling DENV infection.
