In this study, we have attempted to determine whether the systemic administration of CpG oligodeoxynucleotide (CpG-ODN) 1826 would protect mice against systemic lethal Candida albicans infection. CpG-ODNs were found completely to protect mice from death and also reduced the growth of C. albicans in the kidneys. The administration of CpG-ODNs resulted in early interleukin (IL)-12 mRNA expression in the kidneys and an increase in serum IL-12 levels. The protective activity of CpG-ODN was abolished in IL-12-deficient (IL-12-/-) mice, thereby indicating the IL-12-dependency inherent to the effects of CpG-ODN. The protective effect of CpG-ODN was not associated with the activity of NF-kappaB. Interestingly, in tumor necrosis factor (TNF)-alpha-deficient (TNF-/-) mice CpG-ODN neither exerted protective effects nor induced IL-12 expression. These data indicate that CpG-ODN protects animals against lethal C. albicans challenge via a pathway that involves the TNF-alpha-dependent induction of IL-12.

Background: Most RNA-seq datasets harbor genes with extreme expression levels in some samples. Such extreme outliers are usually treated as technical errors and are removed from the data before further statistical analysis. Here we focus on the patterns of such outlier gene expression to investigate whether they provide insights into the underlying biology.

Traditional live attenuated vaccines (LAVs) are typically developed through serial passaging or genetic engineering to introduce specific mutations or deletions. While viral RNA secondary or tertiary structures have been well-documented for their multiple functions, including binding with specific host proteins, their potential for LAV design remains largely unexplored. Herein, using Zika virus (ZIKV) as a model, we demonstrate that targeted disruption of the primary sequence or tertiary structure of a specific viral RNA element responsible for Musashi-1 (MSI1) binding leads to a tissue-specific attenuation phenotype in multiple animal models.

Background And Aims: Viral myocarditis is an inflammatory pathology of the myocardium that involves innate immune responses, especially those involving neutrophils. However, strategies targeting neutrophils to alleviate inflammation have not achieved complete success. Alpha lipoic acid (ALA), a natural organosulfur compound, has the capacity to modulate immune cell behavior.

Cholestasis is a pathological state characterized by the dysfunction of bile acid flow, which could lead to liver fibrosis, cirrhosis, and even liver failure, but its therapeutic agents are limited. The aim of this study was to investigate the therapeutic potential and underlying mechanism of melatonin on cholestatic liver injury. C57BL/6 J mice were fed with 0.
