| Abstract |
Chronic hepatitis C (CHC) infection is known to induce important changes in host cholesterol metabolism. MicroRNAs (miRNAs) regulate the expression of many genes and, in consequence, control various processes, including human metabolism and response to viral infection. Recently, the alteration of the immune-associated miR-146a, which is abundantly present in peripheral blood mononuclear cells (PBMCs), was found in some viral infections. The study aimed to analyse the influence of hepatitis C virus (HCV) infection on miR-146a expression in PBMCs in vivo and in vitro, as well as to assess the possible impact of miR-146a alteration on the intracellular cholesterol level in PBMCs. Blood samples collected from 42 healthy donors and 72 CHC patients were the source of materials. HCV RNA, intracellular cholesterol level and miR-146a expression were determined in PBMCs, as well as HCV genotype and interferon (IFN)α concentration in sera. The influence of miR-146a inhibition on cholesterol expression in PBMCs was analysed in vitro after transient cell transfections with mirVana™ anti-miR-146a Inhibitor. Our data demonstrated an alteration of miR-146a and intracellular cholesterol expression in PBMCs and of IFNα concentration in sera of genotype 1, HCV-infected patients compared to the healthy donors. Also, in cultured PBMCs, miR-146a expression and intracellular cholesterol level were significantly decreased in CHC patients compared to the healthy donors. In vitro blockage of miR-146a expression in PBMCs of CHC patients greatly impaired intracellular cholesterol expression. In these conditions, miR-146a expression was positively correlated with the intracellular cholesterol level. These results suggest that genotype 1 HCV infection may alter miR-146a expression in PBMCs and, consequently, contribute to the observed dysregulation of cholesterol synthesis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 December 2016.
All research outputs
#15,404,272
of 22,914,829 outputs
Outputs from European Journal of Clinical Microbiology & Infectious Diseases
#1,875
of 2,776 outputs
Outputs of similar age
#250,021
of 415,685 outputs
Outputs of similar age from European Journal of Clinical Microbiology & Infectious Diseases
#25
of 44 outputs
Altmetric has tracked 22,914,829 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,776 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.7. This one is in the 25th percentile – i.e., 25% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 415,685 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 44 others from the same source and published within six weeks on either side of this one. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
