Differing from other experimental models, intranasal infection with vaccine strain of Venezuelan equine encephalitis virus, VEEV, (TC83) caused high titer infection in the brain and 90100% mortality in the C3H/HeN murine model. Intranasal infection with VEEV (TC83) caused persistent viral infection in the brains of mice without functional T-cells (-TCR -/-). While wild-type C57BL/6 mice clear infectious virus in the brain by 13 dpi, -TCR -/- maintain infectious virus in the brain to 92 dpi.

View SamplesRationale: Schistosomiasis is one of the most common causes of pulmonary arterial hypertension worldwide, but the pathogenic mechanism by which the host inflammatory response contributes to vascular remodeling is unknown. We sought to identify signaling pathways that play protective or pathogenic roles in experimental Schistosoma-induced pulmonary vascular disease by whole-lung transcriptome analysis. Methods: Wildtype mice were experimentally exposed to S. mansoni ova by intraperitoneal sensitization followed by tail vein augmentation, and the phenotype assessed by right ventricular catheterization and tissue histology, RNA and protein analysis. Whole-lung transcriptome analysis by microarray and RNA sequencing was performed, the latter analyzed using 2 bioinformatic methods. Functional testing of the candidate IL-6 pathway was determined using IL6-knockout mice and the STAT3 inhibitor STI-201. Results: Wild-type mice exposed to S. mansoni had increased right ventricular systolic pressure and thickness of the pulmonary vascular media. Whole lung transcriptome analysis identified the IL6-STAT3-NFATc2 pathway as being upregulated, which was confirmed by PCR and immunostaining of lung tissue from S. mansoni-exposed mice and patients who died of the disease. Mice lacking IL6 or treated with STI-201 developed pulmonary hypertension associated with significant intima remodeling after exposure to S. mansoni. Conclusions: Whole lung transcriptome analysis identified upregulation of the IL6-STAT3-NFATc2 pathway, and IL6 signaling was found to be protective against Schistosoma-induced intimal remodeling.

View SamplesPhospholamban R14del mutazion (PLN-R14del) has been identified in a large family pedigree in which heterozygous carriers exhibited inherited dilated cardiomyopathy (DCM) and death by middle age. To better understand the causal link between the mutations in PLN and DCM pathology, we derived induced pluripotent stem cells from a DCM patient carrying the PLN R14del mutation. We showed that iPSC-derived cardiomyocytes recapitulated the DCM-specific phenotype and demonstrated that either TALEN-mediated genetic correction or combinatorial gene therapy resulted in phenotypic rescue. Our findings offer novel insights into the pathogenesis caused by mutant PLN and point to the development of potential new therapeutics of pathogenic genetic variants associated with inherited cardiomyopathies. Overall design: iPSCs were derived from a female patient carrying a heterozygous mutation (R14del) in the PLN gene. Tree samples were analyzed: Cardiomyocytes derived from PLN-R41del iPSC cells (R14del-CM); R14del-CMs infected with AAV6-EGFP-miR-PLN and R14del-CMs infected with AAV6-EGFP-miR-luc used as a negative control
