As a first step toward this goal, an inventory of allergen labeling regulations was assembled and analyzed to identify commonalities, differences, and future needs.
As for AIT with whole allergen, down-regulation of T cell proliferative and cytokine response to allergen is a consistent observation following peptide immunotherapy (e.g. [ 101, 105]), but the precise mechanism underlying this altered response is not clear.
The '26 allergens rule' [60, 61] is part of the cosmetic regulation and requires that 26 potential allergenic fragrance substances must be named on the labels if they are present above 0.001 percent in 'leave-on' products such as lotions or above 0.01percentt in 'rinse-off' products such as shampoos.
Overall, these data suggest that activin-A may be involved in retaining cDCs in the skin after allergen challenge through the regulation of CCR4 and CCR10 expression.
Regulatory T cells are central actors in the maintenance of tolerance of self-antigens or allergens and in the regulation of the intensity of the immune response during infections by pathogens.
These studies provide significant evidence that IL13 is involved in the regulation of allergen-induced inflammatory response.
Furthermore, PARP-1 appears to contribute to airway remodelling upon chronic exposure to allergens potentially through its regulation of inducible nitric oxide synthase (iNOS) and transforming growth factor (TGF -β [ 6, 13].
Sesame is one of 14 allergens that EU regulations stipulate must be listed in pre-packaged food products made off the premises.
Additional information regarding the regulation of apple allergen gene expression by ethylene and the ethylene inhibitor, 1-MCP, could assist in developing approaches to more effectively regulate fruit ripening.
Allergen inhalation challenge induces up-regulation of TGF-β in the airway epithelium [ 13].
In our acute murine models Creb1 and Crtc down-regulation was detected directly after allergen challenge and further, human CREB1/CRTCs were significantly down-regulated in primary NHBE cells early after IL13 treatment, but returned to normal after 7 days.
