Induction of allergen-specific, tolerogenic, IL-10 and/or TGF-β-producing T-regulatory (Treg) cells that express transcription factor FOXP3 is considered as one of the key mechanisms of allergen-specific immunotherapy. However, little is known of the induction of FOXP3 expression in children during sublingual immunotherapy (SLIT). Recently, also, a novel(More)
BACKGROUND Immunoglobulin E-mediated allergies have doubled in prevalence during recent decades in developed countries.This increase has been attributed, in part, to high hygiene standards, which have reduced exposure to microbes. The capacity of microbes to induce type 1 helper T cell (TH1) responses may imply suppression of TH2 responses. However, little(More)
BACKGROUND Signalling lymphocytic activation molecule (SLAM) and interleukin (IL)-18 induce interferon (IFN)-gamma production from Th1 cells. The allergen-induced SLAM and IL-18 mRNA expressions are increased during subcutaneous immunotherapy (SCIT), but nothing is known about their role during sublingual immunotherapy (SLIT). Transcription factor GATA-3 is(More)
BACKGROUND The first year of infancy is crucial for the development of atopic immune response. Inadequate early Th1 and Treg responses and increased production of Th2 cytokines are associated with atopy. Breast milk contains several immunomodulatory cytokines and other factors that might influence the maturation of the infant's immune system. We assessed(More)
Immunostimulatory properties of synthetic structures mimicking the β-(1→2)-linked mannans of Candida albicans were evaluated in vitro. Contrary to earlier observations, tumor necrosis factor (TNF) production was not detected after stimulation with mannotetraose in mouse macrophages. Divalent disaccharide 1,4-bis(α-D-mannopyranosyloxy)butane induced TNF and(More)
BACKGROUND Allergen-specific immunotherapy (SIT) is known to affect the allergen-specific T helper cell (Th2/Th1) balance and to induce T regulatory (Treg) cells. These observations have usually been made during the first treatment year and often without symptom monitoring. This study was performed to investigate allergen-induced Th2 (IL-4, IL-5)-, Th1(More)
Background: Immunoglobulin E–mediated allergies have doubled in prevalence during recent decades in developed countries. This increase has been attributed, in part, to high hygiene standards, which have reduced exposure to microbes. The capacity of microbes to induce type 1 helper T cell (TH1) responses may imply suppression of TH2 responses. However,(More)
BACKGROUND During infancy, a disturbed cytokine balance leads to an atopic immune response. Many risk factors have been associated with the development of atopy. These include parental smoking, elevated cord blood IgE, early exposure to pets and family history of atopy, but the knowledge of their impact on cytokine balance is limited. OBJECTIVE To assess(More)
