| Abstract |
The protective role of invariant natural killer T cells (iNKTs) against hepatitis B virus (HBV) infection remains controversial. We sought to clarify the role of peripheral iNKT cells during chronic HBV infection. Sixty patients with chronic HBV infection were categorized into an immune tolerance phase (HBV-IT) (n = 16), an immune clearance phase (HBV-IC) (n = 19) and an inactive carrier phase (HBV-IA) (n = 25). Twenty healthy individuals were enrolled as healthy controls. Another 21 HBeAg-positive patients were administrated with entecavir (0.5 mg/day) for 6 months. The percentages of circulating iNKT cells and their IFN-γ and IL-4 expression levels were examined by flow cytometry. The relationships between serum HBV DNA, ALT levels, the percentages of iNKT cells, and their IFN-γ and IL-4 levels were analyzed. Compared to healthy controls, the percentage of iNKT cells decreased in HBV-IT, but increased in HBV-IC and HBV-IA. Circulating IFN-γ-producing iNKT cells gradually increased, whereas IL-4-producing iNKT cells gradually decreased from HBV-IT stage to HBV-IC and HBV-IA stages. The frequency of iNKT cells and their IFN-γ levels were reversely correlated with viral load. The levels of IL-4 expressed by iNKT cells were positively correlated to viral load and the serum ALT levels. After anti-virus therapy, the percentage of IFN-γ-producing iNKT cells increased while the percentage of IL-4-producing iNKT cells decreased. During chronic HBV infection, the percentages of peripheral iNKT cells and its cytokines expressions of IFN-γ and IL-4 showed dynamic changes. The expression levels of IFN-γ and IL-4 were correlated with the clearance of HBV and liver injury. |

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 01 March 2016.
All research outputs
#20,311,744
of 22,852,911 outputs
Outputs from Hepatology International
#388
of 526 outputs
Outputs of similar age
#251,533
of 297,860 outputs
Outputs of similar age from Hepatology International
#7
of 10 outputs
Altmetric has tracked 22,852,911 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 526 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 1st percentile – i.e., 1% 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 297,860 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 3 of them.
