To fully understand the role of diet diversity on allergy outcomes and to set standards for conducting research in this field, the European Academy of Allergy and Clinical Immunology Task Force on Diet and Immunomodulation has systematically explored the association between diet diversity and allergy outcomes. In addition, a detailed narrative review of information on diet quality and diet patterns as they pertain to allergic outcomes is presented. Overall, we recommend that infants of any risk category for allergic disease should have a diverse diet, given no evidence of harm and some potential association of benefit in the prevention of particular allergic outcomes. In order to harmonize methods for future data collection and reporting, the task force members propose relevant definitions and important factors for consideration, when measuring diet diversity in the context of allergy. Consensus was achieved on practice points through the Delphi method. It is hoped that the definitions and considerations described herein will also enable better comparison of future studies and improve mechanistic studies and pathway analysis to understand how diet diversity modulates allergic outcomes. 相似文献

Plasmacytoid dendritic cells (pDCs) regulate immunity and promote tolerance in asthma. Notch signalling is a highly conserved pathway that regulates the immune response; however, its role in pDC-mediated asthmatic airway inflammation is unclear. This study clarified the effects of Notch signalling on pDC-mediated airway inflammation using murine models of ovalbumin-sensitized allergic asthma. RBP-J-deficient pDCs (RBP-J−/− pDCs) were co-cultured with naïve CD4+ T cells and supernatants and T cell subtypes were analysed. RBP-J−/− pDCs were intranasally transferred to the airways of ovalbumin-sensitized recipient mice. Lung samples of all mice were subjected to tests for histopathology, cytokine profile of bronchoalveolar lavage fluid, airway hyperactivity and expression of T helper type 1 (Th1)/Th2 cells, regulatory T cells and type 2 innate lymphoid cells (ILC2s). The results showed that pDCs with and without RBP-J deficiency significantly differed in expression levels of cluster of differentiation 83 (CD83), but not CD80, CD86 and major histocompatibility complex class II. Co-culturing pDCs with naïve T cells revealed a poorer immunosuppressive effect of RBP-J−/− pDCs. This may be attributed to the lower expression levels of inducible co-stimulator ligand and lower production of interleukin 10 in RBP-J−/− pDCs than in control pDCs, which impeded T cell activation and Treg suppression. RBP-J−/− pDCs were associated with high ILC2 expression and severe Th2 immune responses and airway inflammation. Therefore, Notch signalling is critical for pDC-dependent immunoregulation, and RBP-J deficiency reduces pDC-based immunosuppression via T cell activation and Th cell differentiation. Thus, this pathway may be a therapeutic target for pDC-based anti-asthma immunotherapy. 相似文献

Congenital disorders of glycosylation (CDG) are metabolic disorders that affect the glycosylation of proteins and lipids. Since glycosylation affects all organs, CDG show a wide spectrum of phenotypes. We present a patient with microcephaly, dysmorphic facies, congenital heart defect, focal epilepsy, infantile spasms, skeletal dysplasia, and a type 1 serum transferrin isoelectrofocusing due to a novel CDG caused by a homozygous variant in the oligosaccharyltransferase complex noncatalytic subunit (OSTC) gene involved in glycosylation and confirmed by serum transferrin electrophoresis. 相似文献
