| Abstract |
Group 2 innate lymphoid cells (ILC2s) are a newly identified cell population with the potent capability to produce Th2-type cytokines in a non-antigen specific manner. Previous study demonstrated that enhanced circulating ILC2s in cat-allergic patient after experimental allergen challenge, whereas the effects of natural allergen exposure on peripheral ILC2s are still unclear. We therefore examined the variations in circulating ILC2s among asthmatic patients sensitized to different allergens in- and outside- pollen season. 10 patients sensitized to mugwort, 10 patients sensitized to house dust mites (HDM) and 12 healthy controls were recruited into this study. Blood samples were collected from the patients in- and outside- pollens season, 2-3 months apart. ILC2s (Lin-CD127+ CRTH2+) were enumerated by flow cytometry, as well as intracellular IL-5 and IL-13 expression. The levels of IL-5 and IL-13 in supernatants of Lineage- and Lineage+ cells stimulated with IL-25 and/or IL-33 in the presence of IL-2 were measured using a Milliplex human cytokine array kit. An obvious seasonal increases in percentages of total and IL-13+ ILC2s were observed in patients with mugwort sensitization during natural pollen exposure, however, the percentages of peripheral ILC2s in HDM-allergic patients were not affected significantly. A positive correlation between FeNO and IL-13+ILC2s was found in patients sensitized to mugwort. A mixture of IL-33 and IL-25 induced a significant production of IL-13 and IL-5 from Lineage-cells of both mugwort-allergic and HDM-allergic asthmatics. Stimulation with IL-33 alone induced a significantly greater quantity of IL-13 by Lineage-cells from mugwort-allergic asthmatic compared with that from HDM-allergic asthmatics, whereas IL-25 induced a significantly greater amount of IL-5 by the Lineage-cells from mugwort-allergic asthmatic compared with that from HDM-allergic asthmatics. Within pollen season the frequencies and function profiles of circulating ILC2s among asthmatic children are altered dynamically, which may be closely related to the sensitized type of allergens. |

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 19 February 2018.
All research outputs
#19,951,180
of 25,382,440 outputs
Outputs from Allergy, Asthma & Clinical Immunology
#756
of 924 outputs
Outputs of similar age
#327,004
of 451,567 outputs
Outputs of similar age from Allergy, Asthma & Clinical Immunology
#8
of 11 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 924 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.8. This one is in the 15th percentile – i.e., 15% 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 451,567 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 11 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
