| Abstract |
Sublingual immunotherapy (SLIT) is the only therapeutic option for allergic rhinitis (AR) that modifies the immunological process to an allergen, rather than treating symptoms simply. However, its regulatory mechanisms are largely unknown. B-cell-activating factor of the TNF family (BAFF) plays very important roles in the development, differentiation, and proliferation of B cells and T cells. The aim of this study was to identify the role of BAFF during SLIT in pediatric patients with AR. Seventy-two house dust mite (HDM)-sensitized pediatric patients with AR were enrolled in this study. Thirty-six pediatric patients received HDM allergen extract for SLIT and 36 pediatric patients received placebo. Serum and nasal aspirate of different time points during treatment was collected and used for enzyme-linked immunosorbent assay (ELISA) of BAFF and related cytokines, respectively. Peripheral blood mononuclear cells were collected and stimulated by HDM allergen with or without rhBAFF after 12 months of treatment. Our results showed that the expression of BAFF protein decreased during the SLIT treatment compared with that in the placebo group after 6 months of therapy, and this trend lasted for 12 months. The decreased BAFF expression was positively related to Th2 cytokines and increased IL-10 expression. BAFF was also related to local production of IgA. In vitro experiments showed that BAFF can promote Th2 cytokines and inhibit IL-10 expression by PBMCs. Conclusion: During SLIT, BAFF expression was decreased and related to low Th2 cytokine expression and enhanced IL-10 expression. Besides, BAFF may contribute to local production of IgA. Our results suggested that BAFF may be an important biomarker during SLIT. Authors' summary.

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 10 April 2015.
All research outputs
#17,715,061
of 22,747,498 outputs
Outputs from European Journal of Pediatrics
#2,985
of 3,682 outputs
Outputs of similar age
#153,723
of 221,286 outputs
Outputs of similar age from European Journal of Pediatrics
#24
of 46 outputs
Altmetric has tracked 22,747,498 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,682 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. 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 221,286 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 46 others from the same source and published within six weeks on either side of this one. This one is in the 39th percentile – i.e., 39% of its contemporaries scored the same or lower than it.
