Abstract:
Crimean-Congo haemorrhagic fever (CCHF) is a severe disease leading to high mortality in humans. Early diagnosis and evaluation of the severity are necessary to improve patient survival. In a model of CCHF virus-infected interferon-receptor-deficient (IFNAR) KO mice, we found a specific circulating miRNA (c-miRNA) profile when compared to wild-type (wt), resistant mice. Among this response, 20 c-miRNA were shown to be specifically altered, including miR-122-5p, miR-216a-5p, 217-5p, miR-29a-3p and miR-511-5p. Using a logistic regression analysis, a combination of 8 miRNAs allowed a 100% discrimination of mice developing a severe illness (IFNAR-KO) from non-detectable clinical signs (wt).

Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
