( )Dengue virus (DENV) infections are straining public health systems worldwide. Vitamin D, a secosteroid hormone, is currently being investigated for its immunomodulatory effects in DENV infections. The objectives of the present study was to study the effect of 1, 25 dihydroxy vitamin D-3(1,25(OH)(2)D-3) on the expression of genes coding for RNA sensing pattern recognition receptors, downstream signaling components including oligoadenylate synthetases (OAS) and interferon stimulated gene 15 (ISG15) and T helper (Th)1, Th2 and Th17 cytokine response in DENV infected U937-DC-SIGN cells and THP-1 macrophages. U937-DC-SIGN RNA was investigated for the expression of TLR3, DDX58, IFTH1, OAS1, OAS2, OAS3, CAMP and ISG15 genes using gene expression assays. Interleukin (IL)-12p70, IL-10, IL-4 and IL-17A levels were assessed in the THP-1 macrophage culture supernatants. The results revealed that 1,25(OH)(2)D-3 increased the expression of DDX58, OAS1, OAS2 and OAS3 at 0.1 mu M while higher concentration had diminishing effect. 1,25(OH)(2)D-3 enhanced the expression of ISMS and CAMP genes. 1,25(OH)(2)D-3 suppressed the levels of IL-4 and IL-17A. Lower concentration of 1,25(OH)(2)D-3 suppressed IL-12p70 and IL-10 levels while a higher concentration enhanced the levels. The results suggest that 1,25(OH)(2)D-3 may have concentration dependent immunomodulatory effects. Higher dose of 1,25(OH)(2)D-3 might have an immunoregulatory role in ameliorating inflammation during dengue infections. Further studies are needed to evaluate the efficacy of different doses of 1,25(OH)(2)D-3 in preventing severe dengue.

Shilpa Jagatram Tomar, Kalichamy Alagarasu, Ashwini More, Manasi Nadkarni, Rupali Bachal, Minal Bote, Jayashri Patil, Vasanthy Venkatesh, Deepti Parashar, Babasaheb Vishwanath Tandale

Summary: This study investigates the decadal change in chikungunya virus infection in Pune City from 2009 to 2019. It finds a fivefold increase in seroprevalence over the decade, with higher seroprevalence observed among older age groups. Modeling analysis suggests that the age-stratified seroprevalence data from 2019 coincide with a recent outbreak in 2016.

Summary: This study conducted in vitro antiviral screening of plant extracts and purified compounds for their activities against dengue and chikungunya viruses. The extracts from Plumeria alba, Ancistrocladus heyneanus, Bacopa monnieri, and Cucurbita maxima showed activity against both viruses, while the extract from Vitex negundo only showed activity against dengue virus. Among the purified compounds, anacardic acid, chloroquinone, and methyl gallate showed activity against dengue virus, and only methyl gallate had activity against chikungunya virus. These findings provide potential candidates for the development of phytopharmaceutical drugs against dengue and chikungunya.

Summary: The lipophilic fraction of the stem of Ocimum basilicum (LFOB) showed antiviral activity against dengue virus (DENV) but not against chikungunya virus (CHIKV). Analysis of LFOB identified 26 compounds, with beta-sitosterol, stigmasterol, and campesterol being the most abundant. LFOB demonstrated significant inhibition of DENV replication but had no effect on CHIKV, indicating its potential as a prophylactic/therapeutic agent against DENV-2.

Mesenchymal stem cells attenuate systemic lupus erythematosus by inhibiting NLRP3 inflammasome activation through Pim-1 kinase

Honghong Yu, Qi Li, Huimin Zhu, Chang Liu, Weiwei Chen, Lingyun Sun

Summary: The activation of the inflammasome plays a critical role in the pathogenesis of systemic lupus erythematosus (SLE), and mesenchymal stem cells (MSC) have been shown to alleviate SLE by suppressing inflammasome activation. This study found that the NLRP3 inflammasome was activated in macrophages from SLE patients and mice, and its activation correlated with disease activity. After MSC transplantation, the severity of SLE was reduced, and NLRP3 inflammasome activation was inhibited. These findings suggest that MSC suppress inflammasome activation and provide a potential therapeutic target for SLE.
